    I was wondering if anyone had put a larger tire on the interior holder. There is room front, back, and up, but not down. I would like to mount a 33x12.5 tire in there. If there is no way to do this, how close in size should the spare be? Thanks.

    I have a 33x12.50 on a 15x8 rim mounted on the factory inside carrier. On mine the wheel retaining bolt has a slot with about 3-4" of up and down travel to accomodate different size tires. There is also just barely enough room between the tailgate and the rear seat for it to fit, as it rubs both the seatback and the tailgate.

    Duno about the first part of your question but I would say the spare should be the same size as the other 4! running a different size would allow your differential to spin at different speeds and in my mind that = POW!! [​IMG]blown diff!!

    i tried to put a 33" on mine, and it kept the rear seat leaning forward a little bit. i think i may have to go with one of the custom carriers on the back. i got some plans off this board awhile ago, now i have to just get the time and materials together.

    I was looking at it and I saw that it was adjustable up and down, but I didn't know if it went far enough up for a 33. My 33s are coming in this week, so I'll try on one of those on it before I buy a spare. Thanks for the help guys.

    Burt: Um...isn't that what a differential does on a regular basis?

    I have a BFG 35x12.50-15 on a stock rim (accual size 34") in my stock spare carrier. The back seat is straight up & down, not slightly reclined like it should be, but it fits. The small round plate that should fit over the center hole no longer does, but it still gets the job done. Jim.

    Mint90,
    True, just thinking if it were a drastic and constant diference in speed then things 'may' break/heat up then break. And if a tight posi or especially a locker....well you see how brain is thinking now. I just wouldn't want to be the one to test the limits of a diff. or think that running a diferent size tire is OK, I sure wouldn't recomend it for pavement driving.

    My buddy had an 87 with a 35" in the stock holder. It took up almost all the space and he didn't see much out of his rear view mirror. I've had 35s for two years, no spare. I don't have time to 4wheel too much. Once I need a new set I'm planning on saving one as the spare, using the rear bumber carrier used on the Urban Assault project truck.

    Re: Yes it will fit

    I have a 35" x 12.5"/15" BFG All-Terrain mounted on a matching AE 589 15x10 rim that fits fine on the inerior carrier. It does take up alot of room and the seat rubs the tire some but it will fit. My seat still reclines, because I use the round washer (meant for the center hole), the bolt and wing nut in one of the bolt holes in the rim instead of the center hole in the rim. Try that...
