I had a little doubt if they would work. My property has a very steep slope in the backyard to the canal. My original tires slipped, skidded and dug the yard. I wanted to return or sell my John Deere on day one. I got stuck and couldn't make it up the hill. There was power, but absolutely no boost. I was so frustrated and tired mowing the lawn. I'm sure the shouting and swearing upset my neighbors. Installing the tires took about 5 minutes. Literally. I was shocked how well they work. I think I only slipped once and will ride at a different angle next time, but these tires worked so well I forgot how expensive they are. Normally I wouldn't spend $150 on a new mower to fix the problem, but this time I did it and I don't regret it one bit.
