"I have a 1969 Wheelhorse Raider 12. I purchased a set of these and they did not last a winter. I have used all metal chains in the past and have never had a problem but I needed something not to scratch my drive. They had tension, and spring and rubber tensioners on both wheels. I email this company and they said it was my fault. They never did return my email the second time. Interesting that they also banned me from their website. Horrible product. Buy at your own risk. If I could upload pics of the mess they ended up with you would not believe how horrible these chains are made. No fasterners, only cheap metal bent over the chain strap. I could bend them when they got caught in my axle."
