How much can tire life be reduced if they are underinflated?

Car manufacturers have clearly defined how inflated the tires on certain models should be.

Big deviations are not good. Only in some models, the manufacturers indicate how much the pressure should be increased in the case of driving with a full car, with all seats and luggage occupied.

Again, low pressure tires overheat and can reduce their life by up to 20 percent.


This means, instead of lasting about 40 thousand kilometers, you will have to replace them at 32 thousand kilometers. Also, the risk of a tire blowout increases.

In overinflated tires, the sidewalls and tread become stronger than usual, and the tire's contact surface with the road is reduced, causing it to wear out more quickly.

This change may reduce traction and performance. /Telegraph/
