so i have an 03 gt with stock 17 bulitt wheels and want to know if i should go with 17x10.5 or 18x10 in the back.(keeping the stock up front)

 

anyone have any thoughts

 

I share your dilema. I have written to tire and wheel companies with little or no response. 18"/10" is what I am going with for the rear & 18x8.5 for the front. You get a bigger selection with 18"s and the 10's will give you the width. Tire Rack told me the widest that will fit my 05 Mustang GT is a 285/40/18 and suggested 255/45/18 for the front. Is there a taller wider tire that will fit ???? Who knows. Good luck to you.

Those would both fit. I think 10.5 is to thick. Go 18x10 rear and 17x8 front. It will look aggresive.

btw to capstun......you could fit 22's on a s197.(it doesn't look good, but you can)

To OP if you do what i said (stock front/18x10 rears.....make sure to post some pics!!!)
