17x8.5 +42 w/ 245/40/17 or 255/40/17

ommmjido · 03-15-2006, 01:21 PM

im looking to get some wheels in the size 17x8.5 with a +42 offset, and tires in 255/40/17 or 245/40/17 for an 06 WRX. im aware that there's a very high chance that i'll have to roll the rear fenders. im seeing if anyone has experience with a similar setup that can tell me that if i can get away with just negative camber? say -1.5 in the rear? thx in advance!

1. More info needed, specifically the make/model tires you're considering.
2. Remember, all tires/sizes are not created equal, there is no exact standard, so the 245 & 255 you gave us isn't doing much good at this point.

You will most likely rub with either depending on hos low you are. Probably not at stock height.

UL brings up a good point as well.

I am running 255's on 17x8 et 48 with -1.5* camber in the rear and rub on the fender from time to time. Eventually i will get around to rolling the fenders. I am lowered about .75-1" in the rear.

im trying to run 255 Azenis RT615(i know, worst tire in my situation) or 245 Fk451. maybe the FK452 if they're out at that time.

while we're at this, what are the pros and cons of the 255/40/17 and 245/40/17 respectively? i mean, is it really that big of a difference from 245/40/17 to 255/40/17?

bump, any input is appreciated.

245/40/17 is a better ratio.

17x8.5 with 245/40/17
would this rub on a decently lowered 04 WRX??
Front might be ok, but how about the rear?
curious because I am running stechs and they sit a bit low.
Coilovers on its way, but back ordered

ommmjido · 05-20-2006, 06:17 AM

probably will rub if ur fenders arent rolled. would be better if u get coilovers and set enough negative camber.

BTW, r the RS2 coming out with 245/40/17?

dang, I dont want to get 17x7.5 again.
and the rims I want only have 7.5 or 8.5. !!!

They are currently coming out with a few more sizes, but I am uncertain on specifics.
I have been told that for months from Korea

Any updates I will let you guys know!

I'm running 245/45/17 Hankook RS-2s on 17x8.5 et48 rims on an 04' sti on jdm pinks. I did roll my rear fenders but I'm not entirely sure it was nessesary. Never comes close to rubbing with just the rears rolled.

As for pros and cons for the tire that depends on what your gonna be doing with your car. I picked my tire because:

1. it's the max width(245) for the autocross class I plan to run in
2. a taller than stock tire gives the sti a gearing advantage for some course layouts.
3. it's proven to have great dry traction and good wet traction
4. it's cheap

Of the things you could want you need to decide for yourself what your priorities are. Road noise, treadwear, price, dry traction, wet traction, snow traction, racing class restrictions & appearance.

The difference between 255 RT615s and 245 FK451 is pretty ridiculous. Those tires are made for completely different markets. Do yourself a favor and stick to the Ziex & FK line of falken tires if you don't plan on racing. RTs ride really rough, make a ton of noise and wear out fast.
