How to use the old spare tire mount on a 31" tire!

Ok so I tried bungee cords, but they ended up loosening up and the tire was going all over the place in the trunk! So...I bought a battery screw down kit (someone on JF mentioned it on another thread) and attached my tire to the old mount. Sorry for the pic quality (took it on my iPhone in poor light conditions (The iPhone takes good pics!)). The rubber disk really helps to protect the wheel and grip it.

What do you guys think?


Edit: I'm sure you can use the old mount as well if you wanted to attach the wheel using the hub hole or whatever. I used the lug nut hole because I couldn't find the old piece.

I extended mine with some aluminum channel.. drilled 2 holes and used a bolt to attach it to the stock mount. Only using it with a stock tire/rim but wanted it facing out instead of the opposite way..

My local Ace Hardware had short lengths of All-Thread. I bought a 3" piece and a All-Thread coupler that match the factory thread . I screwed the coupler half way on the existing hook in the Jeep, then screwed the all thread in the coupler and tightened it. It was then long enough the use the factory cone and wing nut. This was for a 30x9.50 tire.

I have also chalked it (correct word?) in the front under the tire, so in the case that it tears out the hinges it won't slam into me (hopefully) I did this temporarily, but have found that the hooks on each side preinstalled by jeep are pretty strong.

The battery tie-down and the strap both look like an excellent way to kill yourself if you ever hit anything.

There is a LOT of potential energy in a 100 pound tire when you're doing 60mph - those small screws and the battery hold-down aren't designed to restrain that kind of weight.

Thats why its chalked down, with a wood block on both ends (not seen in photo as gear was being removed), I'm not saying its safe... its temporary, and actually i have seen what a tire can do... saw a guy living out of his car hit the back of a big rig at 70mph without braking, he had tires in his trunk that flew forward. It was great fun putting a cervical collar on what was left.

its a 10mm coupler nut and some 10mm threaded rod to attach to the end of the stock. could still use 2 10mm nuts to act as lock nuts but its working perfectly fine so far. makes use of the stock hardware
