Tire pressure has a significant influence on the safety and fuel economy of the vehicle. These are sufficiently valid motives to justify a level of attention which is often overlooked, given that for the vast proportion of drivers, tyre pressure is only checked on the occasion of the main summer holiday departure. Tire pressure when cold (never try to adjust the pressure while the tire is hot) must therefore be checked regularly (every month), especially before a long trip..

Dont know if its just something about the tires i am unaware of or anything. Excessive inflation too has negative consequences: as well as faster wear in the centre, it also results in reduced adherence, especially in wet conditions, and comfort levels can also be significantly compromised. 33 psi front and rear, two more and mine feels harsh, two less and It feels like a Cadillac.
