245 or 255 Star Spec Z1...8.5" wheel
 

Would a 245 give more traction on a 8.5 rear wheel than a 255? The search engine sucks with numbers...

I have read somewhere that the 255 on a 9" wasnt as good as a larger width...would the same apply to my 8.5?

255 on an 8.5" wheel is fine. I don't know why a 245 on the same wheel would have more traction...

yea i never thought about it but i read a post about 949 Racings new wheels there making and some one mentioned something to this extent but for 9" and 10" wheels

definetly less feel. wouldnt say less grip.

i found the oem 245's on a 9 wheel less snappy then 255 azenis on the oem 8.5" wheel.

What is the stock CR wheel and tire spec? :LOL:

idk...i doesn't feel right swapping my 225 fronts with 215's :ponder:

^he's referencing the fact that the CR rear wheels are 17x8.5 with 255s

yea...i guess ill stick with 225/255 :)

I have been running 255's (both RE01R's and HTR ZIII's) on the stock AP2 rear wheels and they are very squared. With that being said, I'm not sure the 9" rims are really needed. I just wanted the 9" so I could get the lightweight very good priced 949Racing wheels. :)
