What size spare?

Two months ago during the hurricane, I got two flat tires. Luckily, being the well prepared off roader that I am, I had a compressor and a tire repair kit. Unfortunately, one of the tires took it in the side wall, so I need a new spare tire. Right now I have 31s on my TJ, but with my lift I'm planning to go up to 33s at the next tire change.

If I bought a 33 for the spare so that when I eventually need to buy new tires in a year or two, I'd only have to replace the main four, would a 33 work as a temporary spare for 31s?

no, you need to have the tires the same size. Just go to a junk yard or a tire place and get a used 31 for a few bucks.

As long as your not in 4wd you can make it home. Donuts arnt the same size as a full size but you can make it home in it.

do you have a limited slip rear diff or open. open = ok with different tire. limited slip = bad

it could work, but like said above if you have limited slip and got a flat tire on the back you would have to take a tire off the front and but on the back, then put the spare onthe front, a big pain, but would work

depens on how you use it.

differnt sized tires will "GET YOU HOME" regardless of lockers, ls, etc. I will ASSUME you have open difs with your tire size. just "drive it home" dont go on the freeway, dont go in 4wd, dont be an idiot.
in big HUGE letters on the sidewall of donut tires it says "DO NOT EXCEED 45 MPH" yet how may times have you seen them on the freeway?

The ideology of RADICAL Islam is very much like Nazism, except they donít have the cool black uniforms.

Screw it I'm too old for this crap!
