Full Size Spare?

What is the biggest tire diameter that can fit in the cut out in the trunk? I had the joy of getting a flat a couple weeks ago, and I finally realized why the Cobras had a larger spare... It literally doesn't fit over the brakes in the front or the back. I was hoping I can buy a full size spare so that if I ever do have an issue again I can just throw the whole thing on rather than worrying about size/fitment/anything and I freaking hate the black donut. So anyone out there running with a full size spare in the trunk cut out?

2000 Cobra Rs run a full size spare without chassis mods as far as I know. So I believe the largest is a 265/35/18

Thanks Matt.

I had no idea that Cobra R's came with a spare at all.

Awesome. And a Kenny Brown shock tower brand to boot!

The spare is 17" not 18" like the rest of the wheels. I'll check the tire size on it when I get home later.

The tire is not as large as stock size. Guys hav said if you get a flat on back to pull the front wheel and put it on back and not the spare because the spare is smaller and would ruin rear differential.

Just noticed that. You can clearly see it in the pic 245/45/17, same size as stock GTs. Which makes me wonder what size wheel that is, and also makes me wonder if the R Brembos will fit behind my Cobra wheels!!

Yeah, I just saw the same thing. Huge pain in the butt to move everything around that much on the side of the road... It's actually a 98 Cobra wheel. I'm surprised it even works on the front over the Brembo's.

Also the 98 Cobras' spokes did bow out quite a bit, a lot more convex than the other wheels available at the time. Maybe it was just enough to clear the Brembos.

So from what I found using a tire size chart, my tires right now are smaller than stock by a 10th of an inch due to my sidewall ratio of 35 instead of 45. I don't think there would be any issue using a 245/45/17 on any corner due to them being so close in size. What do you guys think?

Wow a tenth is nothing.

I don't think it's a problem.

You're fine, but what size do you have now? Just wondering.

275/35/18 all around. I did have 295's in the rear until they both decided to become screw-magnets. Once they were screwed -literally- I decided being able to rotate my tires would be a good idea so I got two more 275/35/18's. I guess that I could grab another 275/35/18... They are just so freaking huge and heavy to put in the trunk.

Unlike some people here, I have very nice 01 Cobra rear seats. I like suede more than carpet covered wood.
