Was wondering what size tire I should run on my 2010 wrx for the new rims I'm purchasing. There going to be 18x8.5 or 9.5 with a et 35. Plan on lowering the car on bc coil overs, and doing a fender roll.

Year: 2003
Model: WRX
Wheel size/offset: 17x9 +35
Tire Brand: Hankook V12 or HTRZ III
tire size: 245/40/17 or 255/40/17
suspension: ST coilovers and Group-N topmounts
fender mods: none yet

For any of you that have 17x9s on your car. Planning on running 255/40/17 or 245/40/17

What modifications did you need for this to work? I have about a finger and a 1 inch gap all around.

I'm guessing roll flat and pull all around and probably some camber plates?

I had 17x9 +44 with 5mm spacers in the rear running 255/40 advans that run a bit wide on my old 07 wrx. The rears were rolled but not flat by any means. They slightly rubbed but if I would have had camber plates they would have been perfect. No rubbing issues in the front

hmmm 6 mm still might make a bit of a difference, maybe i should go with the 245s, but i heard it wouldnt be the greatest thing for performance.

I eventually dropped down to 245/40 starspecs and clearance was superb still with that light roll. I think with 245's a nice roll and a little negative camber you should be set. I don't think the drop from 255 to 245 will be noticeable in performance with reputable tires

basically just wondering how much smaller these wheels are going to look on the car.. got a good deal on 'em. Im going from my stock set up to these.

if I'm going to do any drops in the future, it'll just be very subtle, not slamming the car.

Any help would be awesome!

Your stock wheels are 17x8 so looking from the side of the car they may appear slightly farther out as the stock offset is +50 something. But overall width is .5" less. On the 2011's I'm pretty sure you can get away with 17/18x9.5 if I'm not mistaken with a +38 or higher offset on stock suspension.

stock: 17x8 +53
new: 17x7.5 +48

the face of the new wheels will actually be 1mm inboard from stock location. Essentially the face of the wheels will sit at the exact same position.

A 235/35 (only a handful of tires available in that size though) or a 245/35 should fit under with just a roll and maybe a degree or two of negative camber.

tire size: 235/45/17
suspension: Stock 2006 OBS
alignment: Haven't done since I purchased the vehicle.
fender mods: None.
spacers: None.

So here's the deal, I bought some 2011 WRX tires that from reading what I could find on here and elsewhere knew would be a close fit if they even worked but figured I could trade or re sell them if they weren't workable. I drove them around my neighborhood and in the garage etc and didn't notice any noises, smells, pulling, loss of turning etc. I then drove about 50 miles with no noticeable drawbacks like pulling, rpm changes, fender rubbing, rubbing on turns etc.

The problem? When I got back I shined a flashlight in and can see marks on the strut housing where the dirt etc has been scrapped off. I haven't taken a wheel back off yet to check the backs of the wheels.

My main question is do you guys think 2-3mm spacers would fix the strut rubbing or would it still not be enough due to width of the tires? I have no interest in running larger spacers but from what I've read 2-3mm is acceptable without causing risks or requiring alterations aside from installing the spacers.

Why? I got 3 of my tires slashed in a mass tire slashing we had here and it's what I could find locally.

If you need more information or pictures to give a better idea of what I'm talking about just say what you need and I can provide it. Also if spacers work any tips on where to get 2-3mm spacers would be great no shops near me seem to carry anything under 5mm and the ones I've found online seem expensive to me like $15-30 per set of 2. On forum search I've seen people saying they should be $10-15 for all 4 but I'm not finding them for that...

That's odd. Well obviously, a different tire could solve your problem, but I'd be curious what your rear tire pressure and camber settings are. If all else fails, then resort to a small spacer.

Oddly it seems to be identical on all 4 which makes sense I guess since it's strut rubbing not fender rubbing but from everything I read I expected the rear to be the issue for them even fitting but they fit completely fine fender side. I can check tire pressure, I don't know how to check camber settings... Will edit in a moment with tire pressures

Tire Pressures with a not 100% accurate gauge all 4 are at 32-33

255/35 for something proper or a 235/40 for a little stretch.

A 255 would fit on a narrow body?

depending on the ride height/camber settings and enough fender mods.

to pull that off youd most likely need to get adjustable rear LCA's if you want to be low.

wheel size/offset: ?
tire brand/model: likely something like an R888
tire size: 275/35/18
suspension: TiC Coils
alignment: camber plates up from, rear adj. control arms
fender mods: will roll and pull, no worries there.
spacers: Rather not.

I am looking for some feedback about wheels that will allow 6-pot calipers to fit. These wheels will be only for the track. The tire size above is nearly identical height to the OEM so that means little fussing with alignment between track days. I currently have RPF1 17x10 but according to the 6-pot templates from Stoptech and APRacing 17" ain't going to cut it.

Looking at Toyo's web page, the preferred rim size for the R888 is 9.5, so that is what I would think I should target and likely other manufacturers for the same tire size would be close.

Any thoughts on a wheel choice? Can anyone think of a wheel that can top the RPF1 18x9.5+38 in terms of price to weight ratio?

Update, so I put on 3mm spacers and was only able to do 5 turns on the lugs so I checked my stock wheels with the lugs that came on the car and noticed they only even did 7 turns. The stock lugs have a 3mm unthreaded bore prior to the threading starting, is this necessary for any reason? I bought a set of aftermarket lug nuts from o'reilly's and they do 9+ turns with no spacers and 6.5 to 7 turns with the spacers in, I figure this is probably fine since with stock everything it was only at 7 turns...

I've read what I can find but was curious on input if anyone sees any potential issues with running it like this?
