Do JK Steel Belted Radialshelp in fuel saving?

JK Steel Belted radials give

more than 5% fuel saving.

This is made possible by the structure of radial tyres. Ordinary tyres have a criss-

cross ply construction. The cords insuccessive layers tend to move against

each other in a scissor-like motion causing extra internal stress.

This is absent in radial construction. Cords in radial tyres are laid radially.

They flex easily - without internal stress. This means less energy is requiredto move the vehicle. You save precious fuel.

An ideal tyre fitment arrangement would be to have all four tyres as radials.

If you use only two, fit them only in the rear.

Why should you use JK Radial tubes with them?

JK Radial tubes have several features which make them ideal for radial

tyres.

• Made of Butyl rubber for better air retention

• 30% higher joint strength Ability to withstand higher rate of

deflections

• Higher gauges

• Shaped to fit snugly into JK Radials. No excess stretch to cause loss

of air

Do retreaded radials give better mileage than retreaded ordinarybias tyres?

There are thousands of retreaded JK Steel Belted radial tyres in operation.

Retreaded, they still give much more mileage than retreaded ordinary bias

tyres. It is necessary to remove them for retreading while there is still 2mmof tread pattern life, when tread wear indicators appear, as shown in the

picture. These TWIs show it is time to retread the tyre.

It is recommended to retread radials by the latest procured process.

Do radials enhance the comfort level while driving?

Yes, JK Tyre radials provide a bonus to motorists in the form of greater

comfort. The supple sidewalls of the tyres act as mini shock absorbers. Theyensure that less shocks pass on to the suspension. This means that your

ride is more comfortable, even at high speeds.

Greater Comfort With Radials







Just how vital is correct inflation pressure? What damage doesunder-inflation cause?

It is very important to correctly inflate tyres. Do not estimate tyre pressure

by appearance. Under-inflation causes fast tyre wear, steering drag,

excessive fuel consumption and tyre failure. Over-inflation causes hardriding, damage to suspension and steering and uneven tyre wear.

Check pressure with an accurate gauge when tyres are cool. Regularly checkyour pressure gauge with a standard gauge for accuracy.

What are the common reasons for tyre damage?

A flat spot can be caused by heavy braking which makes the wheels lock

and scrub the tyre along the road surface.

Feathering is caused by bad wheel alignment, excessive toe-in or toe-outof the wheels.

Uneven wear of the tread is due to bad wheel balance, or a fault in the

suspension, steering gear or bearings.









Many people fit their cars with wider tyres for aesthetic reasons, arethere any technical advantages / disadvantages of doing so?

Although correct tyre size for normal running is the one recommended by

vehicle manufacturer, For special purposes vehicle performance can beimproved by selecting wider tyre with lower profile, which means

maintaining same overall diameter of the tyre, lowering aspect ratio, thusincreasing the tyre width. This is called up-sizing or up-stepping.

There are some safety guidelines, which must be followed while upsizing,

i.e., overall dimensions of the tyre must fall within certain limits. Whileselecting a high performance tyre following must be observed:

1. Clearance

Ensure that any of the tyres does not foul with the vehicle bodyunder any conditions. On vehicles with McPherson strut suspension,

there is very much a chance that super fat tyre fouls with steeringlinkage. Also the tyre should not project out of the vehicle body,

thereby increasing overall width of the vehicle, increasing chances of an accident.

2. Speedometer and odometer errorSpeedometer / odometer are connected throughpropeller shaft of your vehicle and are calibrated

for a particular wheel overall diameter. Changingoverall diameter of tyre much, may lead to

erroneous readings by speedometer andodometer.

In case you observe that tyre overall diameter is decreasing much, you can

increase your rim size. Use following calculation to select correct tyre sizefor larger rim.

For every 1-inch increase in rim diameter, add 20mm to tyre width andsubtract 10% from aspect ratio. But be sure to check PCD of rim and fouling

of new tyre/ rim assembly with other parts





Is there a chance of tyre burst while running at high speeds?

Every tyre has a speed rating, which indicates the max. speed to which youcan run the tyre. See " tyre terminology " section on this website for

details on speed rating.

Two of the tyres on my car are worn and need replacement, where

should I fit new tyres ?

Many dealers and customers alike are of the view that when two tyres on a

car are to be replaced , they should be fitted in front. This was the case fewyears ago, when it was felt that conrtrol of the vehicle was more critical to

front deflations and therefore new and less vulnerable tyres should be fitted

in front.

But the modern recommendation by tyre industry is "New tyres to rear".

This applies to both front and rear driven vehicles. Primarily its justificationis increased safety particularly in wet conditions. Partly worn tyres have

poor water drainage, leading to aquaplaning and thus tendency to oversteerand loss of control. Similarly straight line braking in wet can be adversely

affected.

"New tyres to rear " Principle may not apply to following cases:

1. Where front and rear tyres have different sizes.

2. Where two new tyres are of lower speed rating.

3. On certain 4x4 vehicles, where it would result in significant difference

http://www.jktyre.com/know-your-tyre-terminology.html



http://www.jktyre.com/know-your-tyre-terminology.html



in tread depths.

What inflation pressure should I

have for my tyre?

Correct inflation pressure is indicatedon vehicle placard/ owner's manual of

the vehicle. However for extreme lowtraction situations you may have to

decrease inflation pressures. Thisincreases foot print size of the tyre

and floatation ability and aidstraction. But NEVER DEFLATE YOUR

TYRES UNDER 16 PSI and inflate tooriginal pressure as soon as you

return to tarmac.

Also you should keep in mind that load carrying capacity of tyre is

proportional to its inflation. Which implies that Inflation pressure on your

tyre should be proportional to the load. Excessive inflation leads to lowshock absorbing ability of tyre, impact failures or other casing failures, this

also leads to excessive wear in centre. Under inflation will cause excessivewear in shoulder, heavy steering and poor handling.

A few parts on tyres on my car are wearing faster than other parts,

what can be the reason?

This situation is called spot wear and can be attributed to following:







1. Dynamic imbalance of tyre/ rim assembly.

2. Sudden braking and rapid starting.

3. High run out in tyre/ rim assembly.

In case tyre is wearing diagonally, i.e., wear is starting from one side andprogresses to other side as you move along the circumference, following

may be the reasons:

1. Faulty suspension.

2. Improper wheel alignment.

3. Faulty rotating parts like brakes, etc.

4. Bent beam axle.

How tubeless tyres are different from conventional with tube tyres?

Which is more safe?

Tubeless tyres have a liner of specially made rubber over innermost layer of

the tyre. This liner gives the tyre air tightness and sealing properties asgood as a tube, not only that if a nail pierces into the tyre, liner engulfs itand prevents air from leaking out, air leaks only very slowly when the nail is

taken out.

Thus, come what may, a tubeless tyre never goes flat all of a suddenand hence is more safe.

Following these tips will guarantee that your JK Tyres keep running in perfect

shape for mile after mile. Adopt the JK way to take care of your tyres.






TipsTread DepthCorrect Air PressuresRecommended Inflation PressureTyre Rotation

Tips

1. Do not use tyres with a tread depth of less

than 1.6mm. Apart from being illegal, tyreswith low levels of tread will slide easily,

suffer from extended braking distances and

will be more susceptible to rupturing. In wetconditions the vehicle will aquaplane making

braking and handling almost impossible.

2. Make sure air pressures are correct. Low air

pressure generates heat which can result in

the rubber and cord separating, which inturn leads to the cord becoming cut and

puncturing the tyre. Low pressure also results in excessive wear on the edge of thetyre, shortening the tyre's life. Excessive pressure, meanwhile, results in

unpredictable handling in addition to which, if the tyre suffers an impact, it's easilyruptured and cut. If you brake hard, the tyre may skid, which reduces tyre life as

the centre of the tread becomes worn. Check tyre inflation pressures at least twice

a month. Always check pressures when tyres are cool and maintain the pressurerecommended by the vehicle manufacturer.

3. Remove objects from damaged tyres. Driving with objects such as stone in the

tread groove, or with a nail stuck in the tread can puncture or rupture the tyre.

You should change or repair the tyre immediately on discovering any damage toavoid any further damage to the carcass.

4. Treat abnormal tyre wear immediately. To assure normal wear you should checkair pressures and alignment and rotate the tyres regularly. Advise customers toavoid bad driving habits such as sudden acceleration, braking and cornering.

5. Check the spare tyre. Check the spare tyre's air pressure, existence/non existence

of damage and the depth of remaining tread.

6. Never mount radial tyres on the same axle as non-radial tyres or radial tyres on

the front axle when non-radial tyres are mounted on the rear axle. These

http://www.jktyre.com/care-passenger-cars.html

http://www.jktyre.com/care-passenger-cars.html



conditions are likely to cause vehicle instability resulting in a sudden loss of controland serious injury (see Mixing Tyres).

7. Ensure wheel nuts are securely tightened.

8. Never overload tyres. The maximum load and inflation pressure of the tyres are

moulded into the sidewall. Also, remember; the tyre is capable of carrying themaximum load only if it is inflated to its maximum air pressure.

9. Do not use detergents or chemicals containing petroleum products for cleaning or

polishing tyres.

10.Never fit used tyres unless their past history is known. Tyres age even if they have

not been used or have only been used occasionally. Cracks in the tread or in thesidewall rubber, sometimes accompanied by deformation of the carcass, are a sure

sign of aging.

11.Punctured tyres must always be removed from the wheel to check for secondary

damage.

12.If it is necessary and feasible to repair a tyre, it must be carried out by a tyre

specialist as soon as possible to avoid any structural deterioration. All tyre repairsmust be entrusted to a tyre repair specialist.

Tread Depth

1. As per central Motor vehicle regulations (CMVR)

car tyres must have a minimum of 1.6mm of tread in a continuous band throughout the

centre of the tread width and over the wholecircumference of the tyre.

2. To help recognise when tyres are nearing the

legal limit, tyres are manufactured with treadwear indicators in the grooves.

3. However, despite the law, it is universally recognised in the tyre industry that the

legal limit is wholly insufficient to protect drivers in adverse driving conditions.

4. Drivers are therefore recommended to consider replacing their tyres when the

tread depth reaches 3mm.

Correct Air Pressures

Setting and maintaining the correct air pressures isthe first step to obtain optimum performance and

life from tyres.

Incorrect Inflation

1. Over inflation reduces the ability of the tyre to absorb road shocks resulting in a

much harsher ride. Excessive over inflation may lead to impact fracture or other

casing failures. Over inflation will also cause excessive wear of the centre of the

tyre.

2. Under inflation allows excessive flexing of the tyre, causing excessive internal heat

to build up, eventually weakening the casing and causing damage. Under inflationwill also cause excessive wear on the shoulder of the tyre resulting in heavy

steering and poor handling.

3. Excessive pressure on the shoulder area will increase wear and reduce stopping

distance.

Tyre Sizing Systems

Over the years there has been many different methods used to size tyres. Many of these arestill in use today, with the ISO Metric Sizing System the most widely used.

1. Numeric Sizing System

This first system developed for tyre sizing was used until thelate 1960s, but provided only the cross section width of the

tyre and the rim diameter in inches. If the section width

ended in zero (e.g., 7.00-14 or 7.50-14), the tyre had acommon aspect ratio of about 92. For section widths not

ending in zero (e.g., 8.25-15), the tyre was considered "lowprofile" with an aspect ratio of about 82.

2. Alphanumeric Sizing System

In 1968, a new concept was introduced worldwide. The

Alphanumeric sizing system is a load-based system wheretyres are designated by their load-carrying capacity and

aspect ratio. The first letter is the load and size relationship,with letters ranging from A to N. The lower the letter, the

smaller the size and, of course, the lower the load-carryingcapacity of the tyre.

3. P-Metric Sizing System

To accommodate the smaller tyres used on compact cars,the P-Metric (Passenger Metric) system was created in 1976.

The maximum inflation pressures of P-Metric tyres wereraised for lower rolling resistance.

4. Metric Sizing System

Because Europe primarily uses the metric system of measurement; the Metric sizing system was developed. It isessentially a conversion of the Numeric system. Section

widths are notated in millimetres instead of inches.Originally, tyres not identified with an aspect ratio were

assumed to be 82-series. When 60- and 70 series tyres

appeared, the aspect ratio was added to the nomenclature, similar to the P-Metricsystem.



5. ISO Metric Sizing System

The International Standards Organization (ISO) Metric

system combines the Metric system with a service

description. The service description provides the load indexalong with the speed rating symbol.

6. Millimetric Sizing System

The Millimetric sizing system is similar to the Metric systemexcept that the rim diameter is also represented in

millimetres.

7. Light Truck Numeric System

Similar to the Numeric system for cars, it lists the section

width in inches, construction type, rim diameter in inches,plus the light truck designation.

8. Light Truck Metric System

Similar to the P-Metric system, except the P is replaced withthe LT light truck designation. Also, LT-Metric and P-Metric

tyres differ in construction.

9. Light Truck High Flotation System







Other Markings

DOT Codes - Coding satisfying the requirements of the USDepartment of Transportation contain a mixture of letters and numbers such as DOT DVDE

MTA 129.

E-Marks - Tyres for sale in the European Community must carry an E -Mark in accordancewith ECE Reg 30 - eg E4 027550.

Aspect Ratio (or sidewall height)

Aspect ratio is the ratio of a tyre's width to it's height. A 70 series tyre, therefore, is a tyre

whose height is equal to 70% of its width. Lower Profile Tyres hence have lower seriesnumbers.

Speed Ratings

All tyres carry a speed symbol in the form of a letter indicating the maximum speed for







which the tyre is intended. This indicates the maximum speed that the tyre can sustain for aten minute endurance without coming to pieces and destroying itself and the car it is on.

The table below shows which speed goes with each letter :

Tyre Placard

1. A vehicle's original tyre and wheel specifications are detailed on a placard affixed

to all vehicles manufactured on or after the 1st of January 1973.

2. The tyres conform to specific load carrying specifications as recommended on the

vehicle manufacturer's tyre placard, as required by Australian Design Rule 23(ADR23).

3. Tyres should be appropriate to the type and size of rim fitted to the vehicle.

Decoding all that information on the sidewall

All numbers, letters, symbols, mysterious codes. Here's the important stuff:

A : Manufacturer or brand name, and commercial name or identity.B & J : Tyre size, construction and speed rating designations. See tyre sizes and speed

ratings below.C : Denotes type of tyre construction.

D : M&S denotes a tyre designed for mud and snow. Reinforced marking only whereapplicable.

E : Load and pressure marking requirement.







Tyre Sizing Systems

Over the years there has been many different methods used to size tyres. Many of these arestill in use today, with the ISO Metric Sizing System the most widely used.

1. Numeric Sizing System

This first system developed for tyre sizing was used until thelate 1960s, but provided only the cross section width of the

tyre and the rim diameter in inches. If the section width

ended in zero (e.g., 7.00-14 or 7.50-14), the tyre had acommon aspect ratio of about 92. For section widths not

ending in zero (e.g., 8.25-15), the tyre was considered "lowprofile" with an aspect ratio of about 82.

2. Alphanumeric Sizing System

In 1968, a new concept was introduced worldwide. The

Alphanumeric sizing system is a load-based system wheretyres are designated by their load-carrying capacity and

aspect ratio. The first letter is the load and size relationship,with letters ranging from A to N. The lower the letter, the

smaller the size and, of course, the lower the load-carryingcapacity of the tyre.

3. P-Metric Sizing System

To accommodate the smaller tyres used on compact cars,the P-Metric (Passenger Metric) system was created in 1976.

The maximum inflation pressures of P-Metric tyres wereraised for lower rolling resistance.

4. Metric Sizing System

Because Europe primarily uses the metric system of measurement; the Metric sizing system was developed. It isessentially a conversion of the Numeric system. Section

widths are notated in millimetres instead of inches.Originally, tyres not identified with an aspect ratio were

assumed to be 82-series. When 60- and 70 series tyres

appeared, the aspect ratio was added to the nomenclature, similar to the P-Metricsystem.



5. ISO Metric Sizing System

The International Standards Organization (ISO) Metric

system combines the Metric system with a service

description. The service description provides the load indexalong with the speed rating symbol.

6. Millimetric Sizing System

The Millimetric sizing system is similar to the Metric systemexcept that the rim diameter is also represented in

millimetres.

7. Light Truck Numeric System



8. Light Truck Metric System

Similar to the P-Metric system, except the P is replaced withthe LT light truck designation. Also, LT-Metric and P-Metric

tyres differ in construction.

9. Light Truck High Flotation System







Other Markings

DOT Codes - Coding satisfying the requirements of the USDepartment of Transportation contain a mixture of letters and numbers such as DOT DVDE

MTA 129.

E-Marks - Tyres for sale in the European Community must carry an E -Mark in accordancewith ECE Reg 30 - eg E4 027550.

Aspect Ratio (or sidewall height)

Aspect ratio is the ratio of a tyre's width to it's height. A 70 series tyre, therefore, is a tyre

whose height is equal to 70% of its width. Lower Profile Tyres hence have lower seriesnumbers.

Speed Ratings

All tyres carry a speed symbol in the form of a letter indicating the maximum speed for







which the tyre is intended. This indicates the maximum speed that the tyre can sustain for aten minute endurance without coming to pieces and destroying itself and the car it is on.

The table below shows which speed goes with each letter :
