What is the largest size tire you would feel comfortable mounting on the spare carrier without seeing it overstressed?

The question I think is more what is the largest tire you can mount on a stock Tracker tire mount.  I had a 29" tire on mine and it was just rubbing the bumper.  I now have 31-10.50-15  tires so I modified the stock mount and I am still using the mount. I prefer the stock mount on the door over any other option I have seen. The tire mounted on a seperate mount supported by the steel bumpers can create rattles and is an extra pain it the butt to get to things inside the back door.

I am more interested in the stress factor. I got rid of my plastic, slotted the carrier, and so on.... The information I am looking for is how much weight (in terms of tire size) can the door/carrier withstand. I am looking at creating a suzuki to toyota adapter that will also lift the spare tire up a hair... I am going to run a skinnier spare but hoping to keep the height. If I have to I will go with a swing arm... just a few other important things on my list first... like steering...

I modified mine to clear a 31" Swamper. It has held up fine. the rest of the rear door is rusting away though.

I bet that 31 SS weighs more than what I was wanting to put on...


255/85/16

i have a 31x10.5x15 on my stock carrier(2dr'89) and it seems just fine.
it doesn't touch those little bumper things, but doesn't seem to move at all(no noise).
heavy truck tire.

I would guess the 4dr door and hinges would be able to handle more weight???

Actually, the rear doors on the 4 doors and the 2 door tintops are the same, so I would guess the hinges are too.

You are wise sir!!! Any time I think of 2 dr kicks, Convertible comes to mind... I forget about the tintops...

So, would I be able to mount a 255/85/16 without ripping my door off like what happens to sami's with too large of a tire on the back???

I would say YES. By the way a 255/85 is bigger than a 31", tire isn't it ?

quite a bit...  but hopefully no heavier than a 31 10.5 super swamper...

I had a 31" with aluminum rim on mine I made it fit tight and made sure no bounce it was nice, but when I went to 33s I threw the spare inside.

...and is an extra pain it the butt to get to things inside the back door.

Yeah, those swing away's are hard to figure out  

I've had a 31x12.5 on mine for a while, I had to lower the air pressure to about 5psi to squeeze it on.

Was that on a 2 door soft top?

Hey Element, I wondered about this as well, I'm only runnin 30s now but down the road I want to updrade to 32 or 33s, and I don't want an extra carrier on the bumper.  I planning to weld some reinforcement to the door(inside or out havn't decided) and mount spare tire bracket to that.  Maybe reinforce/upgrade hinges.
