What is right tire psi?

[Christian Gañac]

both of my cars (a Dmax and an OTJ) have 33 psi at front and 35 psi at the rear. Pag nag exceed kasi dun matagtag yung ride at during long trips, prone sa pre mature wear yung tires dahil excessive heat from the brakes as well from the road increases the tire pressure slowly. as for fuel consumption parang same lang rin.

You don't get more brake heat from high inflation pressures. You get excess heat from the road due to sidewall flex, which happens more at lower pressures (as seen in the Firestone-Explorer scandal).

I've run 45 psi in the Crosswind for years with no excessive center tread wear. In fact, the outside of the tires still wears out first.

Ang galing mo talaga chief! ;)

Would you highly recommend then that i/we increase my/our tyre pressure across all the wheels?

Thanks for the advice.
