Re: Spare Tire Suggestion for 275/55-20
You want a spare that's the same diameter. There are calculators online that can help you figure out the best size that matches diameter but is a little narrower to mimic the OEM "full size" spare so that the lid sits flush. I believe that if you remove the plastic inserts in the well, you can achieve something like 32" which is the max for the four corners, anyway, without physical modification of the JGC. OEM "full size" spare uses an 18x8 wheel, if I'm not mistaken.
