My tires say 31x10.5xr15. What does that mean? And what other sizes would fit on my wheels. I have a 3.5" pro comp lift.
I plan on buying from treadwright..

 

31" tall, 10.5" wide and a 15" rim. Stock rims are 15x7" I believe so I think you sould be safe running a 32" and maybe 33" tires, but then you have to worry about backspacing. Stock rims have 5.25" backspacing which will cause 31" tires and up to rub on the LCA at full lock.

 

You can put them on 15 x10's ...
I suggest 15x8s with better backspacing.

 

Maybe I read his first post wrong, but Im not sure if the OP is asking about the tires or the rims, haha.

 

I think tires lol
