When i got my single seat buggy i had a set of grooved 44" tsl, grooved to the cords with tubes in all tires and they hooked awesome in the loose stuff and were tough as nails, but rode with a group of Toyotas on BFG's at hale mtn and they all walked up obstacles that I had to beat on. I went home that afternoon and listed my wheels and tires for sale and my buggy sat on jack stands for 3 months while saving up for a set of BFG's and 17" beadlocks. I love them. I would be interested in a 39-40 sx sticky if they ever came out with one but that's probably the only other tire I would want to run on my current buggy
