Frequently asked questions
What is the conversion between PSI, Bar and kPa?
1 Bar = 14.5038 PSI = 100 kPa. So 32 PSI = 2.207 Bar = 220.7 kPa. Indian tyre pressure gauges often show PSI or Bar; European cars often specify Bar.
Should I check tyre pressure when tyres are cold or hot?
Always check when tyres are cold — before driving more than 2 km or after the car has been parked for at least 3 hours. Tyre pressure rises by 4–6 PSI when warm. Do not deflate a warm tyre to meet the cold specification.
What happens if tyre pressure is too low?
Under-inflated tyres overheat, wear faster on the shoulders, reduce fuel efficiency by up to 3%, and can cause a blowout on highways. They also reduce steering response and braking performance.
What is the recommended tyre pressure for Indian roads?
Most passenger cars in India recommend 32–35 PSI front and rear. However, always refer to the sticker on the inside of your driver door or fuel cap. Carrying a heavy load warrants higher pressure (check owner manual).
Does altitude affect tyre pressure?
Yes. At high altitudes (like Ladakh or Spiti), atmospheric pressure is lower, so a tyre inflated to 32 PSI at sea level will register higher at altitude. Many tyre manufacturers recommend slightly reducing pressure at high altitude — consult your manual.
