I just bought a set of 18x9/10 deep dish bullitt wheels for my 94 GT.  I was wondering what tire size I can run, any input? 

I appreciate any insight anyone can give.

Thanks.

This story from the 5.0 website might help, even though it talks about brake upgrades, it also covers installing Bullitt wheels.

I run FR 10th AV Cobra wheels in 17x9s on my 94 GT. The front is very full, but the rear has a little more room. BFG 275/40-17s fit well. I prefer to be able to rotate the tires to get the most milage and wear out of them.    TJ  

I've never run 17's but I know with my 18x9.5 a set of nexxen 275/50 series in the rear and 245/45 in the front the handling is excellent in wet and dry conditions.  No you can't rotate them but why would you want to rotate something that you're gonna burn off anyway  

go to www.americanmuscle.com they have a section that tells you how to buy tires for your rims. and they suggest the correct sizes too.  

18x9=275 35 18
18x10=315-35 18  

I have the same size rims and am running 265/35 up front and 295/35 out back.  

All,  I'm running a set of '03 Cobra wheels on 99 Cobra with Nitto 275's on 9.5's and contemplating going with 315's this go.  Anyone running these and with what spacers if any?  

I have American Muscle 18x10 S Style wheels on the back of my '94 Cobra, and am running 285/35 Sumitomos. I think a 295 or 305 would look awesome. Good luck.
