JK Tyre & Industries Ltd
Air Pressure
Maintain correct air pressure at all times to ensures safety of your tyre. This also leads to reduced vibrations giving you a safe and smooth ride.
  • Maintain inflation pressure as per your vehicle manufactures guideline
  • Check inflation pressure once a week when the tyre is cold
  • Ensure air tightness by changing valve when new tyre is fitted for tubeless tyre.
  • Always have a valve cap on
  • Do not forget the spare tyre. Keep it correctly inflated for emergency


Wheel Balancing
Unbalanced wheel can cause vibration and uneven tread wear leading to premature wearing of the tyre and of the suspension and steering parts.

Always balance the tyre-rim assembly:
  • When a new tyre is fitted or if the tyre is removed from the rim
  • If some vibration is felt or irregular tread wear in noticed
  • After every 5000 kms your car travels
  • Uniform tyre assembly is essential for superior handling characteristics.
  • Tyre manufacturers globally provide a "Red Mark" on the sidewall known as uniformity mark and it needs to be matched against the "Blue Mark" provided by the rim manufacture.
  • This is applicable both for tube type and tubeless tyres.


Wheel Alignment
Alignment is the adjustment of the rear and front suspension parts. It ensures your car drives straight down the road and handles better. Tyre life and fuel economy is enhanced with correct wheel Alignment.

Have your vehicle Alignment done if :
  • A different in vehicle handling is noticed
  • You have hit something or driven on very poor road
  • A wear pattern developers on the shoulder of the tyre

When to change my tyre?
Every JK Tyre has a Tread Wear Indicator (TWI) situated on the shoulder. The TWI is a ridge at the base of the tread grooves. When the rubber on the tread of the tyre is worn up to the TWI i.e 1.60 mm, it will be visible as a solid bar of rubber across the width of the tread. When this happens the tyre must be changed immediately. However we recommend that you change your tyre before the tread wears down to the TWI.

Always use new tubes with new tyres.


Can I Mix tyre types?
Tyres of different size designations, constructions, and stages of wear may affect vehicle handling and stability.
  • Do not mix sizes. All four tyres must be of the same tyre size of same brand
  • Do not mix radial and bias-ply tyres. All four must be either radial or bias - ply


Can I mix radial and bias tyres?
In case mixing of tyres is unavoidable:
  • Never mix radial and bias tyre on the same axle
  • If two radial and two bias tyres are to be installed on a vehicle, the two radials must be installed on the rear axle and the two bias on the front axle.


Can I replace the tyres on my car with a lower speed-rated tyre?
  • When replacing tyre with a particular speed rating the new tyre must be of the same or higher speed rating.
  • Vehicle fitted with tyres of different speed ratings will affect the handling of the car. Refer the vehicle manual to known the correct speed for you car.


Can I replace my present tyres with tyres of a different size?
  • Never choose a tyre that is smaller in size or has less load-carrying capacity than the tyre came with the car.
  • Tyres should always be replaced with the same size designation - or approved options - as recommended by the vehicle or tyre manufactur.
Your current tyre size can be found by reading the markings on the sidewall


Where do I Install new tyres if I only buy two?
New tyres must always be fitted on the rear axle. New tyres provide better grip than old tyres and when they are installed on the rear.
  • This reduces the changes of your vehicle fishtailing or hydroplaning in wet conditions
  • Increase vehicle stability when braking
  • Improves grip when cornering

How to read tyre markings?
Tyres have a code system moulded into their sidewall, which allows you to understand their technical capabilities. This code provides information on the tyre construction (e.g. radial), its size, its load-carrying capacity and its speed rating.

For example, the code on a common tyre is:
205/65R15 95H
  • 205 indicates the nominal section width of the tyre in millimeters (205mm).
  • 65 indicates its aspect ratio, a comparison of the tyre's section height with its section width (65 indicates the height is 65% of its width).
  • R indicates radial ply construction
  • 15 indicates the nominal rim diameter code.
  • 95H is a symbol indicating the maximum load capacity and speed at which the tyre can be safely operated, subject to the tyre being in sound condition, correctly fitted, and with recommended inflation pressures (95 represents a maximum load of 690kg per tyre; H represents a maximum speed of 210km/h).

Advantages of Tubeless Tyres
  • Slower deflation on puncture leading to more safety
  • Less vibration leading to a more comfortable ride due to its unique construction
  • Betterfuel efficiency as the absence of tube reduces the tyre weight
  • Increased tyre life as absence of tube reduces frictional heat build-up


Tubeless Tyre - Success Mantra
  • Tyre Mounting/Demounting must be done using automatic machines
  • Properly trained personnel must do tyre repair
  • Wheel Rims of good quality and condition must be used


Adopt These Driving Habits to Increase the life of your Tyres
  • Don't speed. Excessive heat is generated when driving at high speeds. This heat increases the rate of tyre wear and reduces the tyre's durability
  • Avoid fast turns on curves and around corners, and avoid fast starts and panic stops
  • Don't ride on the edge of the pavement or drive over curbs, potholes, or other obstructions


JK Tyre & Industries LtdTyre Rotation
Regular tyre rotation optimizes the life of your tyre. Have your tyres rotated every 5000 to 8000 kms even if there is no visible uneven wear.
