48mm offsetwhats the offset on the wheels?
These will be race only tires. No way would I DD on a6. Hoosier recomend a 7-8.5" rim for them, I could also get them in a 225/40r17 setup.I dunno guys, a 225/45r17 tire on a 8.5" wheel seems probamatic to me. Yeah, the tread width might look like a good match, but what about how the sidewalls meet the rim? I'm not sure you wouldn't get an odd wear pattern because of that.
So even they agree that a 8.5" rim in getting to be too wide for them. Do they make the A6 in a 245/45R17? Can you get the wheel in 7.5" wide?These will be race only tires. No way would I DD on a6. Hoosier recomend a 7-8.5" rim for them, I could also get them in a 225/40r17 setup.
I will be running in SMF. Boy all these number are starting to confuse me. So what your saying is at 245/40/17 on an 8.5 will be fine even when lowered?What class are you autocrossing in? If you're running DOT R-compounds, you're most likely either in SM or SMF, in which case go with the 17x8's - or Stock, in which case you are limited to a 17x7 inch wheel, period, and to offsets between +48 and +36. I have run on 245/40/17 hossiers on the stock rims for quite some time, and Ionick05 has my old stock rims with 245/40/17 Hoosiers on them now. I have Motegi's in a 17x7 forGS this year, with 245/40/17 BFG R1's.
A 245/40/17 is as much rubber as is going to go under there without a widebody kit, lol.
What 245 do you run? 245/40? How lowered are you?Big brother is 100%. 245 a6 i like that tire, use it on 9.0 and 9.5 wide rims
stretching the steer tire works okay not to worry; tis the rub that can give problems, but with the springs i use its not an issue on my RL...
Yes that all makes more sense now. I am looking to get rubber next year. To many expensive things planned this year.A 245/40/17 is correct. If you're ordering rubber right now, the Kumho V710's are on sale at TireRack for $173 right now - if they'd had that deal when I ordered my R1's, I'd probably have 710's, lol.
17x8.5 is fine, just get the correct offset. Mid to high +20's would be optimal, low +30's would be acceptable, anything over a +32 or so MAY have rubbing issues.
Hope that helps.
I ran Hoosier A6s in 225/45 x 17s for one year with stock spec (and stock) rims -- 17 x 7 -- with no problems -- I took a National Tour event in Texas two years ago with this wheel/tire combination. I ran Hoosier 225/40 x 17s on stock spec rims without any problems last year. Bottom line, you don't need to buy 8.5" wide rims if you're only going to run 225 rubber!If I got a rim at 17x8.5 and tires (Hoosier a6) of P225/45ZR17 which have a 8.8" tried width and was lowered by 2"-2.5" would I have problems with rub or clearence?
