never heard of the Jeep Sarah. must be a new model? oh, you mean the sahara? JK!
there are so many options for a tire carrier. you can get bumper+tire carriers or just oversize tire carriers. a few people on here are opting for just the tire carrier (from what I've been reading). it's the Teraflex hinged tire carrier, it's $400 I think, but it doesn't require a new bumper and holds up to a 35" tire just fine, apparently (I do not own one).

if you think $499 is expensive, go check out the rear bumpers that come with tire carriers.....woah.
and yes, ACE is the more reasonably priced bumper+tire carrier combo, IMO.
