I was wondering if a 18x9 rim with a tire 275/35ZR18 would fit with out having to roll my fenders?

 

With a 1" drop..

 

I think a 275 tire would look kind of dumb on a 9 inch wide rim. 265 would be better and has less change of rubbing. I had 18x9.5 +22 with 265s and the back rubbed a little bit, front was fine.

 

275/35 is recommended for 9-10.5" wheels. 265 is technically too small, but I agree it's got a better chance of not rubbing.

Knowing the offsets is crucial to answering this question.

 

Wheel Diameter (Inches) - 18"
Wheel Width (Inches) - 9"
PCD Bolt Pattern - 5x114.3
Offset - +30mm
Hub Bore - 73mm

 

+ 30 offset would have me believe you'd be fine or very very close to fine.

 

Did you just say that a 265 is technically too small for a 9"-wide wheel?

 

Am i getting this right, the lower the offset the more clearance?

 

Depends on whether "clearance" = avoiding the strut/knuckle or "clearance" = avoiding the fender. Better to think of lower offset as "wheel sticks out more" and be done with it.

 

Yea thats what i want, if i have to ill roll the fenders a bit. What a good size tire for a ADVAN RS rims? Im sure ADVAN makes a 9.5 inch rim so that the 275 would fit better.

 

A 275 will be much happier on a 10"-wide rim, but your original goal of 275s without doing any fender mods is pretty much doomed. Have you read any of the myriad threads on this?

 

Yea i tried and got confused, 10" with 275 would i need to do heavy fender rolling?

 

I haven't looked into this, as it doesn't apply to me, but I'm 99% sure that this topic has already been beaten to death and I believe that the answer is Yes. I'm here only because I thought someone suggested that a 265 is too small for a 9"-wide wheel; that sort of thing can't go unchallenged. If anything, a 265 is too big for a 9"-wheel.

 

Agree! 245 is fine, 255 is fine, 265 should work but is wider than the wheel certainly. I WOULD NOT go 275 on a 9" wheel.

 

Yea I would just use a 265 wheel on the 9. Or you could even run a 255. The +25 offset looks way better IMO.
