We've used AM Performance wheels and AM supplied treads for many years and LOVED them. Last year, it appears AM got a different batch of material in, or something changed, as the rough-top was wearing out very fast compared to what we'd experienced in the past with similar drivetrains and wheel sizes.
This year, we again bought more AM material and used it at our first event. All of our rough-top treads (4" 6wd modified AM14) failed worse than shown in the picture above, we had nothing but the belting and rivets left and it was only 1/2 way through qualifications at Kettering!
For the last two events, we used a 3-ply blue nitrile- no issues at all, awesome stuff!! Highly recommended!!
