I have 18x8 with 225s in the front and 18x9s with 255 in rear. S03s all around.

I have done a search but could not find anything.

 

you need to check with the company that made your tires. every tire is different. i think tirerack.com has all the info you need.

 

 

Should be 33 front, 34 rear.

 

i run 35 all the way around.

225/40/18 fronts
255/35/18 rear
goodyear eagle f1's

when i did a search on it, i think the answer was use the same pressure that is suggested for the car; no changes necessary which is 32 psi.

however, i think it feels better with a few more lbs.

 

revjunky, I hope no offense for asking here,
could you tell me where you got that info from?
Reliable source?
thanks

 

It doesn't matter what size and kind of tire you have, you always use the stock tire pressures for the vehicle unless you are autoxing and know what your doing. You NEVER follow the pressure on the tire as that is the max pressure that the tire can handle.

 

I don't really go by the chart either but I figure for those that have no idea the chart's a good place to start. As most know, tire pressures vary can vary a lot with personal preference, compound type, sidewall load index, suspension setup, etc.

I got the chart from a post made a while back by "Tireguy" aka "Arnelr21". He works for America's Tire Company and I assume that's where the chart comes from. I think they use that chart to set or recommend tire pressures to their customers.
