So I found this ad...
" I have 4 33" SuperSwamper tires, with a spare 33" tire, all on plain black rims in my garage that I would like to get rid off. They are SuperSwamper TSL's (15/35-15TL) with 15" steel rims, 6 bolt pattern, and a lot of tread left."
He said he will separate and give me the tires for $300. I will be using these for offroad only on a second set of rims, so they wont be for road use.
