Another question then. I haven't looked around my spare tire to see how much extra room there is, but I'm getting 35"s put on Friday and my spare is still a 265 stock. If I had a used 35" tire on my spare rim would it still fit up under my truck?

A BFG 315 (34.5") will fit, might be able to squeeze another 1/2" or so. If you have aftermarket exhaust that could be a problem also.

BFG 315 mounted under bed.

Everyone should have all five tires the same size!

I agree that you should run the odd size on the front if you get a flat.

A 315 will fit even with a 4 inch MBRP exhaust, but be sure to slide it back as far as you can to keep it from rubbing the diff.
