I have an 89 single cab 4x4 without a lift and am currently running 31-10.50s. I'm looking to get new tires soon and recently came up on a set of ome 12" wide rims. Since I don't have a lift and everything's pretty much stock I want to run 31s. looked quite a few times online and only could find drag radials in that size.
Has any one ever seen this size tire?
If so where?

 

You can get a 13.5 swamper in the 31 size. That should fit.

Thats a wicked wide rim. Unless its a killer deal, I would look for a 8 or 10" rim.
