that's a pretty broad question....
The pretty standard "BIG" tire for the WRX/STIs wind up being 245/255s.
But.... i think some A Stock STI guys have squeezed 275 Hoosiers on their stock wheels. wouldn't recommend that for the street...

WRX8XB · 01-09-2006, 02:25 PM

there is a big thread in the motorsports thread.

but the Cliffnotes are 255/40 17 is about as wide as you want to run on the stock wheels.

I have the 255 rt615s on my car and i'm lowered on STi pinks, fits like a dream.

Rumor has it that a 48mm offset and 255s lowered on pinks doesn't fit.

the stock +53mm offset works perfectly.

rankink · 01-09-2006, 02:42 PM

275's will work on a 8 inch wide wheel on a stock STi, but needs to be a 48 offset. The stock 53 offset would rub against the strut. As WRX8Xb said i would not run anything more than 255's on the street on stock size wheels.

8.5" wide +45mm lowered on Tein S-tech, 265/35.........so dreamy

jrmsti · 01-10-2006, 06:39 AM

thanks for the help but i will not being them on a stock wheel as i'm going to get a set of bbs lm's rim so tucking tire wld not be an issue.

subieworx · 01-10-2006, 08:31 AM

255 Falken 615's will rub when lowered on an 04 with 17x8 et 48 wheel. May fit on an 05 though. As others have said you really don't need more than 255 for the street.

BBS LM's won't fit, unless you're talking about the JDM-specific ones. Find the wheel you want, post the size and offset, and we'll tell you what we think will fit.

Farnsrocket · 01-10-2006, 12:50 PM

I wanna chime in here. I have an 02' WRX with 8.5" Advan RCII's +48 with Bridgestone Potenza 245/40-17's, lowered with JIC's.
The rears just edged the fenders and after some hard driving you could see small, spaghetti like rubber on the outer corners of the tires. Well, I rolled my fenders this fall and they have not rubbed since.....I probably gained 5/16" of clearance.
I was wondering if I could get some 255's in there? Anyone have luck with this width and are the STi fenders different from the WRX? Thanks!

jruben4 · 01-10-2006, 01:08 PM

I was planning on a 17x8.5 wheel, 48 offset w/ a 255/40 tire; On a 05 sti stock springs. Should fit, right? I thought I'd do 255 the first set of tires, and if there's plenty of room try 265/275 next time...

You could prrbably fit 255's, but it will depend on what 255's you are talking about. Some are wider than others. The 04 sti fenders are the same as the wrx's. The 05 on sti have wider fenders in the rear.

On stock springs you should be fine, but again it depends on the tire you use.

Yeah, I have been comparing tread widths of 245's and 255's and some are quite different, by as much as .4"
All the Bridgestone Potenza models I looked at seem to be the wider than a comparably sized Falken Azenis, except for the new Azenis 615....it is consideraly wider.
Thanks for the info!!!!

titsataki · 01-10-2006, 04:49 PM

Anyone tried Michelin Pilot Sport in 255/40/17's on the stock 05 rims with JDM pinks?

How is the fitment and how is the noise?

Do you autoX with that setup? Also, did you roll the fenders or do anything else to make them fit? Any rubbing?

I have an '04 as well and have been hanging back on buying 245's for the stock rim as it appears that I'd rub with the lowering that the JDM pinks gave me.

JustinWRC · 01-13-2006, 01:11 AM

im running 255/40's on 17x8 w/48 offset with no rubbing (now) cutting rear fenders fronts fit fine. jic flta2s lowerd about 2'' front 1.75'' rear. tires will almost always fit just depends on how bad you want them too

the fender its self isn't wider, there is just less metal on the "lip" (the part people usually roll.

UltimateLurker · 01-13-2006, 10:40 AM

Exactly. The inside lip provides structural integrity and a convenient place to put spot welds, but the '05/'06 STi's don't have the lip at all, the quarter panel comes straight down and stops, so there is an extra bracing piece added to the outside (ugly IMO). Funny thing is, there is no way in hell that the stock suspension/wheel/tire combo would ever touch this area, even under super aggressive driving, so they made the change to allow after-market spring/wheel/tire combo's. Bravo Subaru!

z71amigo · 01-14-2006, 03:10 AM

i am getting 255/40/17 mounted on my stock wheels on monday. I will take some pictures and let you know how they fit. BTW i am stock height.

section width is where the rub happens, Pilot Sport Cups go up by .9" from 245 -> 255... they are practically a 275.
