Every car comes with a manual where you can easily check for the recommended levels of inflation pressure for your car tyres. This one thing can be considered one of the most important things as it helps in the long-lasting stability of tyres.
One the biggest reason for tyre damage is under inflation which leads to severe cracks and loss of air in tyres. This mostly leads to excessive sidewall flexing, reduced lead capacity, increased rolling distance which further directs to mechanical damage as more heat gets generated.
Tyre maintenance is no easy job where under-inflation is harmful, over inflation is harmful too, as stiffness in tyres increases the driver might feel uncomfortable while driving, unwanted vibration can be felt too!
