31's to 32's

buying some new tires, any advantages of going from 31's to 32's?

wondering if the price difference is worth it.

Well 32's you are going to have to have some nature of lift or another way to deal with some rubbing if you don't have one already. In my experience, 32's are where you really start noticing the shorter gears becoming an issue as well. Basically less than 3.73's will start to feel slow. Advantages are a bit more underbody clearance, and depending on width comparisons, more contact patch.

Some thoughts....Have you had any ground clearance issues with the 31"s (such as getting stuck)? If not, would it be for looks?

I had 32's years ago and was at point faced with an issue of needing 1 replacement and the only tire shop in town had to order it. (They had tons of 31's and 33's in stock). Just something to consider.

What type of tire are you thinking of going with? Do you offroad much? Do you disco?

I up-sized from 31 to 32 last year and love it. I went with the BFG MT KM2, great tire but they are expensive. It would have been cheaper to go 33's but I knew my little 4 cyl would struggle too much.

I am planning on upgrading to 32's soon and I also have a 2.5L. How does your jeep differ from the upgrade?

I had 30x9.50x15s BFG T/A KOs and I thought about going up to a 31x10.50x15, but I did side by side comparions at some local tire shops and there really wasn't much difference in size. So I looked at 32s and 33s. I think the 32s are about perfect (as long as you're not doing extreme offroading) I did alot of research on tires and their actual sizes (they're not always the same as they are advertised by the manufacturer). I found that the GoodYear Duratrac 33x12.50x15 is actually a 32x11.50x15 when it's mounted on a 15x8" rim and the psi is properly set. a 2" lift would be ideal if you just do mild offroading, if you think you'll get into more than the mild stuff, I'd say 3" would better suit you. here's mine with the Duratracs and one showing the new and old tires side by side just before I put them on.

Heres mine. 32x11.50 on 15x8 wheels with a 2" budget boost. Needs alittle more lift so i can let it flex. I dont do that much wheeling yet so not that big of a deal.
