lemarin Posted August 27, 2015 Report Share Posted August 27, 2015 I'm looking at new rear tires as they worn out, the front ones are still great. I want to buy the same Eagle F1 Supercar G2, to match the front OEM ones. Now, I'm wondering if 305 is too wide for my GT500 2011 with SVT PP ? It makes only about 2% of difference in diameter with OEM, but does 305 is too wide for the 20x10 OEM wheel ? Any rubbing expected ? Money is no object as there's only 20$ per tire of difference. I'd like to have your opinion guys ! Thanks ! Quote Link to comment Share on other sites More sharing options...
MTYQIN Posted August 27, 2015 Report Share Posted August 27, 2015 lemarin, I'm running 305-30 MPSS on 20x10.5" rims at the rear on my lowered 2012 and the fit is fine. Absolutely no rubbing or any fitment issues. Think you'll like the wider stance of the 305 in back. Good luck with the mod. Quinn Quote Link to comment Share on other sites More sharing options...
lemarin Posted August 27, 2015 Author Report Share Posted August 27, 2015 Thanks for the input. I'm also wondering if 305 is too wide for the OEM 10" wide rim ? Quote Link to comment Share on other sites More sharing options...
blk12svt Posted August 30, 2015 Report Share Posted August 30, 2015 The OEM rim is 9.5 and too narrow for 305, if you follow manufacturers advice for rim width. Even 295's aren't supposed to be mounted on 9.5's but a lot of people do it . I've made a decision not to and my 295 MPSS are still laying in the garage floor as I hope to find a pair of OEM 2014 rears to widen someday.

lemarin Posted September 6, 2015 Author Report Share Posted September 6, 2015 I didn't know it was 9.5" only ? I taught it was 10" wide.....optionnal SVT pack wheels. Quote Link to comment Share on other sites More sharing options...
blk12svt Posted September 8, 2015 Report Share Posted September 8, 2015 I didn't know it was 9.5" only ? I taught it was 10" wide.....optionnal SVT pack wheels. Yes, rims are measured inside the outer flange. I've never actually measured one myself but the Ford specs call them 9.5's. Good luck!!

bob2012 Posted October 6, 2015 Report Share Posted October 6, 2015 I have a 2012GT500 with SVT Wheels. could I widen rims to 11" to accept 315's. would there be any clearance problems. I lowered car about 1.5" Thanks Bob Quote Link to comment Share on other sites More sharing options...

I lowered car about 1.5" Thanks Bob I can't answer your question with any degree of certainty given you are lowered 1.5". I will say this however, I put my 2014 on a lift to get a good look at the clearance and it looks to me like an OEM wheel could only be widened by 1" and still maintain adequate clearance. assuming you are leaving everything suspension wise stock. You might go 1.5" but if it's too close maybe shimming the wheel out with a 1/4" spacer would work. You might ask this question on fordgt500 dot com. There is a guy over there that goes by catmonkey who is a real wizard on what works and doesn't work with wheel/tire setups. Good luck!
