has anybody ever put a 275/40R18 or 275/35R18 on the OE (18x8.5) wheel for 06 IS350? does it fit? rub?

Tks

 

265/35-18 fits.

275/35-18 may not, due to minimum wheel width requirements.

even if you could, you'll want to opt for the 35-series for wider-than-255-treadwidth tires for clearance.

 

If a spacer (of which I do not recommend using) is thrown into the equation, it might work.

 

^ and just exactly how does the use of a spacer help fitting 275's onto a 8.5"-wide wheel?

 

Obviously not the fitting the tire onto the wheel question...of course it can fit. The fitting into the wheel well without rubbing.

 

^ the rear wheelwells are actually very deep. people just assume the rear wheelwells are not, because they try to run stupid-low-offset wheels for the cool parking lot stance (that's marginally functional, but i digress...).

265's on oem 18x8.5's will not require spacers for the tires to clear suspension components.

if 275's fit on oem 18x8.5's ("if" being the operative word), you probably still won't need spacers.

 

So wide on such a small width question is Why?

 

not planning on putting spacers.

oh so you are saying the inside of the tire may have a chance to rub on the suspension, i was thinking the outside of the tire may hit the fender.

You wanna see a big tire on a small wheel...my friend had 225/40/14 BFG drag radials mounted on OE Honda 14x6 steel wheels. LOL! Now that was a joke.
