I have Racing Hart Z5000's in 17's with 205/40/17 tires. ive always heard i should put more pressure in the tires but sears said otherwise....what should the pressure level be?

 

35 lb all around but your gas milage may go down beacause of lage wheels ;unles you have light wheels like 15 lb

 

with all due respect, please know what you're talking about before posting something like that.

your pressures should stay about the same, as you're not going with any wider wheel than stock. if you go wider, then there's a larger contact patch on the tire, so you can drop the pressures somewhat to make up for it.
