Spare Tire Question...

When I bought my ‘79 CJ5, the previous owner had 31” tires and a 31” spare.

I replaced the four tires with 33x12.50R15 tires, but never upgraded the spare.

Seems to me, maybe one time, I put the 31” spare on and it functioned, but obviously not ideal.

It really should be same height, so was planning on buying a 33x10.50R15 and a 15” rim to fit it (existing rim is like 6” wide, maybe 7”).

A full 12.50” width spare seems excessive as the spare tire is mounted on the rear carrier and sticks out, plus the 12.50’s are heavier, etc.

Is a 33x10.50 R15 tire as the Spare a good way to proceed?

Thanks

Yes. I did the same thing. Also it is a huge weight savings hanging off the back of the jeep. Save your back.

Thank You.

I thought about trying to find an even skinnier, 33-inch tall light truck tire that might still fit the narrow rim. Maybe a military tire. Something that is the correct height, but narrower and lightweight.

Some people just bring a tire repair kit and air pump/compressed air bottle, but what about a bent or broken rim or torn sidewall?

Wise Jeepers bring a spare tire, a repair kit, and an inner tube. You can stitch together a cut up tire with bailing wire, pad the repair with rags, and air up the inner tube.

I haven’t carried a spare tire in 5 years now. When I bought my 40s I only bought 4. I carry a good plug and patch kit and I have on board air. I have never once damaged a tire badly enough that I couldn’t fix it with a couple of plugs or less. I’ve never once used a patch. I have also never bent or broken a wheel.

Not to be a Richard about it, but if you don't have spare and need one, your junk is sitting off to the side of the trail while the rest of us move on. Unprepared is not a good way to make new friends out in the wilderness. Any organized event or well run 4x4 club requires a spare tire.

I have cut several sidewalls, and even cut two on consecutive trail days. I bought a replacement and a spare when we got back to town.

Sounds like you need a better tire with a tougher sidewall. I ran ProComp Xterrains for years. Only ever punctured a sidewall once and 4 plugs fixed it right up. Now I’m running bias ply Trepadors.

And no matter how tough your sidewalls are, crap happens.

I have KM3's which have a pretty tough sidewall. I lost one on an unexpected tree root that would have taken out any tire. No amount of plugs would have fixed my 3" gash.

If I didn't have a spare, the entire trail would have been blocked for quite some time.

I always carry a spare and have a plug kit, never needed ether, but I have them if I do.
also have a small 12V air supply
Spare needs to be same circumference if you have a limited slip diff or locker.
Open diff a smaller tire is not ideal but will work.

Whats over that next ridge?
