I have a set (5) Super Swamper TSL's for sale. They are 13-38-16. I put them on my rig 2 years ago and went to Moab and Disney. Then I spent all of 03 building a park and did very little wheeling. I have been on about 10 trips this year. I would say 4 of them have about 60% tread and one has 80%. There are no chucks out of the lugs. I custom cut the tread blocks like the pro rock competitors and they work extremely well on the rocks. They are located in Kansas City (Olathe). A real bargain at $650 for the 5. PM me with any questions. This is my first endeavor on pirate. So if I'm doing something wrong, I'm sure you guys will let me know. Thanks.
