    I bought a brand new (was a spare on a jeep that was totaled) Toyo Open Country AT 35x12.50r17 today for $60. What a deal. And, they even mounted the tire on my rim at no extra charge and lowered the pressure until it would fit in the stock spare location and crawled under there to get the tire aligned while I cranked it back up. About 10 psi for this tire listed at 34.4" to fit. It appears to be limited by the fore-aft direction, and it looks like I could easily grind off about 1/4" or more of the receiver, which would make it flush with the welds, so no strength lost. Anyone else ground down the receiver and found that it created more room for a 35" tire to run at a few more that 10 psi???

    m25443, FYI, the tire that you see listed as 34.4", I also found listed at a just slightly larger at a 34.5" by another tire dealer. It's probably just a rounding difference by the other dealer. Another poster here stated that a similar BFG KO2 tire (34.4" spec) fits fully inflated, so that 0.1" could be enough difference in the full inflation of the Toyo. Instead of grinding off 0.250" (1/4"), starting off removing less with just 0.1" might do the trick. Can always remove more material later, but one can't replace too much material removed. I doubt that the receiver square tube's length which butts up against the spare tire has a tight tolerance to begin with during it's manufacturing. I haven't done it though due to running 34.06" tires, but it doesn't sound like a bad idea.

    Not too much of a fan of these receiver's powder coated paint jobs due to they get subject to some major rusting much more than any other piece attached on my trucks. So the least material removed by grinding the front end of the receiver square tubing off, the better chance that rust won't work itself back into the welds, even after priming and repainting. The receivers probably rust more due to being in the very back and take the brunt of the winter road salt, rain, and impacts with off road use.

    Wow...I've been thinking of mounting a full-size tire on my Reb for awhile now, so this is timely! I'm still running my stock 33s, so I'm betting I can get one of those in my spare well easily enough if it's aired down.

    I have my fury 35x12.5-18 mounted on the stock spare 18” rim. It was a no go and I didnt wanna air it down. So I ripped all of the parts off and am having a mount built that inserts into my b&w turnover ball and I’ll just mount it in bed....only need it when I’m going out into desert anyways. Plus I get a workout every time I put it in and take it out. Plus I see more of my Thuren parts hahaha

    Well wtf were they thinking there!? I find it odd they would bother doing it on the power wagon but not the rebel. Makes no sense.
