I think you should go with what the manufacturer suggests. But I have tires with max psi at 50, and i keep them at 45.

There should be a sticker when you open your glove box....

Atleast there is on my 90T.

And it says 35psi.

Also it depends on what your doing...

Yeah well i notice that when i turn the steering blows like it feels like my tire is going over a bump or something but its just itself lumping over..
so around 42 front 44 psi back sound good?

whats the downfall of tires that are to close to the max, not that i intend but
if for some reason 42 and 44psi are to much or to little whats the downfall on each side?

they should be anywhere from 32-36. the more pressure the less traction and more wear in the middle. less pressure more traction and more wear on the outside edges.

just because your tires say 44max does not mean thats what they should be at.

35psi is the spec from toyota.

i run mine at 32 stock size tires.

no one said 44 max. 51 max yes.

Go with what feels the most comfortable.

a lot of tires its only 44. was just a example as every tire is different.

either way its not recommended by the tire manufacturers to run your tires at its max psi.

Lol, no do not run them at max psi. Unless you plan on drifting, I believe they do.

the one with 1-3 passengers. our cars are only a 4 seater including driver so 5 is out of the question.

35psi
