These are my favorite rims, and I think I will do this or mimic True Bullitt Blue's moves with the 18" BUllitt replicas in the rear with the stock 17" rims in front. His car looks proportional with bigger tires and wheels in the rear. If I use the Cobra R 18's all around, can I run 35 series tires up front and 40 series tires in the back for some proportionality? Will they clear the front fenders(outside lips, particularly) under suspension compression? Last, but not least, I am assuming spacers will not be needed in the rear with these rims. Thanks Much!

griff, my personal opinion is that you shouldn't use wider tires in the front than in the back! if you change to the Cobra 18" wheels, you should run the 35's in the rear and 40's in the front!!
use some of the small spacers these guys are talking about on the rears if your not happy after putting 35's on the back!

No spacers necessary with the Ford Cobra R wheels. As for tire size, keep in mind that with the width of the Cobra R wheels (18 x 9.5 I believe) you're looking at some really big tires. You might check over at www.corral.net for owners of 99+ GT's that have these wheels and pick which tire size you think looks best.
thanks guys. Let me be more clear: I want taller tires in the rear, and if they are a little wider, that is ok too. I do not want wider tires in the front. I just thought lower 35's would not be necessarily wider than 40's in the rear. Is it possible to do this using 18's all around?
griffbl,
For example, BFGoodrich G-Force KDW's in 265/35-18 are 10.7" wide on a 9.5" rim and 25.3" tall. 265/40-18 are 10.7" wide on a 9.5" rim and 26.3" tall. So if you put the 40 series in the back it will be taller. For comparison, 275/40-18 is 10.9" wide on a 9.5" rim, and 26.7 " tall. Our stock tires are 9.6" wide on a 8.0" rim and 25.7" tall. I plan on going with 18x9" Bullitt wheels with 245/40-18 in front and 275/35-18 in back. Both of those sizes are the same overall diameter. Anything wider than 275 in the back will require 18x10" wheels. The Cobra R has 265/40-18's all the way around. Good luck!
Brad

Brad-
You answered it all, I think! Thanks again! One More:
What size is the 18" Cobra R rim ideally suited? i.e not too wide or narrow. It looks to me that for proportion the answer is to place 275x40x18's on the rear and 265x40x18's in the front.
Best,
Griffbl

griff,
I have been wrestling with that question for a while now. I change my mind daily. The Cobra R wheel is 9.5" wide. According to Nitto, you can fit a 285/35-18 Nitto 555 on a 9.5" wheel. That size is 25.97" in diameter, so slightly larger than stock(25.7"). 265/35-18 is 25.28" in diameter, slightly smaller. If you don't have your car lowered and don't plan to than I wouldn't go smaller than stock. Lower profile tires give the illusion that the overall diameter is smaller than it really is. It's all personal preference. I went and looked at a Cobra R today and I verified that it had 265/40-18's all the way around. The front tire was flush with the fender. Remember that the Cobra R rim has a different offset than the stock 17's, so it sits out a little more. You can run into probs with a lowered car if you go too wide up front. The 265 looked plenty wide in the rear, but a 275/40-18 would work also. I have confused even myself, so I am sure I have confused you too. Sorry if that is the case.
Brad

I just purchased the Original 2000 chrome cobra r's (had to wait extra time for the originals to come out, but it is worth it)and they are beautiful. I have 275/35 tires and the fit is great, no issues at all (and i even have steeda springs on it which lowers it 3/4 inch more).
Brad-And Others:
No doubt 265's are plenty wide. I just want to put 275x40's in the rear..for a little more height than the front. I will put 265x40's up front, or that is the plan. My springs are stock. They won't rub on the front fenders will they?
