I can tell you that I'm an aggressive trail rider that's probably 80% trail and 20% off trail here in Michigan. After 1200 miles these studs have endured rock, sand, constant road crossings and hitting logs under heavy throttle and as far as I know they are still in near mint condition. They were easy to install, especially with your install tool. I'm super happy with them. I do need to get more from you guys as I only filled the premolded holes in the center of my track. I want to put them in before this season. Thanks. Matt Serra MNR Auto LLC 2023 skiddoo xrs 850
