TYRE CARE TIPS FOR PASSENGER CAR TYRES
Correct level of tyre pressure is vital. Consult your owners manual about the required pressure recommended by the manufacturer and get the inflation checked at regular intervals, preferably from same filling station. While driving on highways or motorways at higher than normal speeds, ensure that your tyres have approx. 3 PSI more pressure than normal. Revert back to normal pressure in the city.
It is necessary to rotate the tyres after every I 0,000 kilometers for even wear and longer life.
Always get your tyre/wheel assembly dynamically balanced for a comfortable and smooth ride. Wheel Alignment Mis- Aligned tyre leads to higher fuel consumption, less driving comfort. Check wheel alignment every six month.
Drive consistently, accelerate and brake gradually and smoothly.
Tyres are classified according to their construction as:
1 – Radial.
2 – Bias or Diagonal or Cross Ply.
In Radial tyre, ply cord, either steel or fabric, run straight across the tyre from bead to bead. In addition, the radial tyre has a belt of additional plies, usually steel running down the centre of the tyre between the carcass and the tread.This construction allows the radial sidewall to be much more flexible while the tread is much stiffer than bias ply tyres.This allow the tyre to absorb impacts and limit sideways movement of the tread while cornering.
In the Bias ply tyre, also known as diagonal ply tyre, plies run from bead to bead at an angle (hence the name bias).With layers of plies criss-crossing each other.This construction makes the sidewall relatively stiffer and the tread area softer.
You may wish to know what size tyre you use.You can get the tyre’s size by reading the side wall.
The Numbers / Lettering stands for:
195 = Width of the tyre in millimetres
65 = Height of the tyre sidewall as a percentage of the width.Also known as the aspect ratio
R = Radial Construction
15 = The diameter of the wheel
91 = Load Capacity of Tyre
H = Speed Symbol. Indicates the max. speed (210 kph) for the tyre at full load.A
