Default 2015+ WRX 275 Tire Fitment

Looking for information on specs from people that have fit 275s on the 15+, Figure it should fit with a 9.5in rim with 38-45mm offset but not sure. If anyone can confirm fitments for 275s thatd be great, I havent been able to find much.

I had 275/35/18 on Enkei RPF1 18x9.5 +45, all on stock suspension, with really no problems. I quickly switched to 265s

I got the set of Enkeis with used 275s already mounted. When it was time to change the tires due to low tire tread, I decided to go with a narrower tires for weight savings and to avoid rubbing if I decided to go lower with coils without having to do any fender mods...

did you bother reading the insanely large 2015+ fitment thread?

Start there if you want to start putting ridiculous sized tires on your car.

a 265 is the most popular tire size on that chassis.

a 275, depending on brand, isn't going to be a hell of a lot wider. Unless you are using a 275/40 (too tall) or a wide tire like a star spec, fitment shouldn't be difficult and could probably get away with just a roll.

use an offset calculator and a tire sizing calculator (and the manufacturers listed dimensions) and you should have a pretty solid idea of how it should fit.

I've seen (in person) 265-35-18 on an 9.5 wide wheel and plus 42 offset fit 15+ with no fender mods and still have a little room. I'm assuming that a 275 would be ok with out mods on stock suspension. I would just like to see it.

So I have been running 275/35r18 on 18x9.5 +40mm on stock suspension for about six months now with now issues. All my fenders are rolled though and it is going to be lowered on coilovers in the coming weeks.

I'm looking at running 275/35/18 on 18x9.5 +45 Advans lowered on RCE Yellows. I currently run 265/35/18 with no rubbing or fender roll. From my research 265 is 10.7" wide and a 275 is 10.9" wide. Not much width difference. Do you think it would have been fine without rubbing? Also, how did it work out lowered?

I can fit 275/35/18 Hoosier A7's on an 18x9.5 +42 wheel square with the car pretty freaking low, <2 finger wheel gap, and not rub anywhere with a slight rear roll in the rear. This runs skinny for a slick but is still wider than most 275's.

A 295/30/18 Hoosier A7 barely kisses the spring on my coilovers on the front of the car on the same wheels (+40 is ideal for the front). No way is the 295 fitting in the rear with the same wheel without a serious roll/pull. It is a gigantic ****ing tire lol.

Bridgestone RE71R in 275/35/18 barely rub on the fender lip on 18x9.5 +38 in the rear. Again probably a +40 or +42 wheel wouldn't be a problem for these in the rear. No issues in the front with the +38 fitment.

Michelin PS4S in 265/40/18 look ****ing badass on the 18x9.5 +38 but I'm getting some serious rubbing in the rear, going to try raising the car some on the side it's rubbing really bad and maybe try to get a few more mm out of the rear fenders. No issues on the front.

i ran 275/40 17 on a 17x9.5 +38 rpf1. it was a nice fitment. i probably could have gotten away with 285/40 17 on a 17x10 +38 at stock height but never got the chance to test it out.
