1999 MJ Posted February 23 Share Posted February 23 1). Largest full size spare tire that will fit under the truck in the factory location? a). I imagine there is a weight limit to the MJ cable system. b). Is there a vehicle I can search out for a 16 inch steel rim, that will complement 16 inch XJ aluminum rims? *** Goal is a 30 inch spare tire, on a 16 inch steel rim. 2). MJ needs floor pans. I plan on swapping a ‘97-‘01 XJ interior to this truck. Which floor pans would you recommend? MJ floor pans? XJ floor pans, because of the ‘97-‘01 interior swap? *** off the wall idea, I’d like to find Renix “rocker” seat bases, that I could put into this MJ & then bolt the ‘97-‘01 seats to the Renix base. I’m wondering if the "rocking" Renix seat base would allow for the ‘97-‘01 to hinge forward, to access the rear of the cab? Side note, I have a 1999 2dr XJ 4x4 5spd as a donor / parts rig to allow me to accomplish the majority of this. Please feel free to chime in with FYI’s & things to think about / consider.

I have a 31x10.5x15 spare under my long bed. It fits great. (I am not sure how it would fit under a short bed). The factory cable lifts the tire just fine. I did add a ratchet strap for extra security. Jeep Liberty's had 16 inch steel rims that will bolt right up and have the same back spacing as the MJ wheels.

neohic Posted February 23 Share Posted February 23 A 30” is about as big as you can go under a short bed. I removed the riveted in panel behind the bumper to get mine to fit. Link to comment Share on other sites More sharing options...
89 MJ Posted February 23 Share Posted February 23 I’ve got a 31 under my short bed. Link to comment Share on other sites More sharing options...
GonzoTheGreat Posted February 23 Share Posted February 23 I second the ratchet strap. I trust the factory cable only so much. Stuff whatever size tire you can fit under there, but use a ratchet strap for cheap security. for the floors, it won’t really affect the interior either way. XJ floors can be made to work, but don’t perfectly match the stiffeners in the “frame” underneath. I used the old key parts pans and had to modify slightly. They now have their MJ specific ones, and I haven’t tried them, but they look like a good fit. Link to comment Share on other sites More sharing options...

watchamakalit Posted February 24 Share Posted February 24 31" under a short bed here. Did have to remove riveted panel as noted already. Voice of experience, the factory winch holds till it don't. I lost a brand-new 31" general grabber on a turbine wheel, because I didn't have a secondary strap. Link to comment Share on other sites More sharing options...
PIKE Posted February 24 Share Posted February 24 33x9.50r-15 under my long bed. Fits just fine. Link to comment Share on other sites More sharing options...
Pete M Posted February 26 Share Posted February 26 inch measurements for tires vary WILDLY which is why some tires fit and others don't. any 30 will fit, some 31s will fit, and a couple guys have fit 32s or 33s underneath. and this assumes that all MJs have the same space available.
