what the preasure should be when u upgrade your RIMS

it really depends on your type of tyre... it's best to check the tyre manufacturer's specs as each tyre will vary accordingly.

Exactly what I thought too.
What tyres are you using? Check the sidewalls. I'm sure the maximum pressure is stated on it, then you can go by it.

i know it very well but most time we dont put maximum pressure ........right ?

No..of course not.
But it should give you an indication of what pressure you can max it up to. :)

for normal driving = 35psi
Cruise to mountain = 30psi

i have more grip with 30psi...yes i can feel the Difference.

i will try it haha but will 30psi hurt my wheels ? i mean the 185/55/15 is already request 32psi...........

what about for 205/45/16??

don't think it will hurt the wheels....i had drive a car with 10psi with all tyres ...there was like no problem at all....but i am sure it is not too good for the tyres.....

lol 10psi..that is definately no good
