Alright Ive done some research and Im getting confilicting info. From this website regarding the Y33's Im seeing folks running middle to uper 30's on tire pressure and some of you are all the way up to 40 and above. I know not to use max pressure but even the 80% of max, that some of you have suggested, still seems high according to the load/inflation table I am looking at. Stock 215 60 16's max load is 44PSI X 80%=35.2PSI which is 5+ PSI over stock according to the door jamb sticker.

Stock tires 215-60 16 w/load rating 94 are s/b set at 30PSI all the way around. I got 245 45 18's with a load rating of 96. According to the tables in the link it appears to me I should remain right around 30 PSI.

I dont know maybe Im reading these tables incorrectly? http://www.toyo.com/docs/tires...s.asp

35 psi - 38 psi should have you in the ball park. Remember, unloaded there is more weight up front.

Monitor wear across each tire with a tread depth gauge. An infra red temperture sensor can reveal a lot also when ecah tire is scanned across its tread after a high speed cruise.
