Can I put 31" tires on my stock rims or will I need to get new ones?

 

u can but since the stock rims are usualy 7inch,it will make the tire taller and make it more narrow,thats what my buddy told me that builds mud trucks,he has 10inch wide rims on 15inch wide swampers

 

You can if you have 15" rims. I have 16" rims. I found the meteric conversion for 32's and put them on. If you dont have a lift, dont get 31's, they woun't fit.

 

31's will work just fine with at least a 3" lift. (No trimming anyways)
I run 31x10.50x15 BFG M/T KM1's on my stock alloy wheels. They will rub on the control arms. To counter this I installed WJ LCA's, they have the S curve that allows for larger tires. Hope this helps!

 

you can put 31's on stock rims. if they will fit under your jeep is another question. if you dont have a lift, you can trim. if your lifted your fine. also on stock rims they will probly rub on you lca's
