I am looking at new tires for my 18x9's tirerack(i know, scary.) tells me I can fit 275's on a x9 wheel, but that we can only fit 235's on our car...

can I fit 275's without rubbing?

how about 265's ? they are the same price

and I understand that with 275/35/18's my speedo will be off about 2% , I dont mind..

 

255's or 265's, anything thinner and it will look a bit wierd on a 9, not matching type of thing. Seem like pretty heavy wheels, but with that new y-pipe, I dont think it'll matter too much.

 

Can I fit 265's or 275's though on our car without rubbing when i turn the wheel and stuff though? They arent tooo heavy, I want to say 24lbs for polished 18x9's? ... and yeah, the umm ypipe and noisemaker help too, plus i've got slicks coming so it wont matter at the track.

and i dont street race (remembers all the times in court.. .... !!)

 

Those are pretty light for 18X9's. You may need a weird offset wheel to do 275, I know unclemax, which I'm sure you know of him too, he has 265's in tha back.

 

in the back? what does he have up front ?

 

I'm not sure what he has in teh front, but I'm sure they're not wider than a 245. 4th gen Maxis seem to have more room for wider wheels and tires out back though, so the 275's may rub, or even look weird.
