I had a 20yr old piece of junk mower that would go anywhere without chains, regular turf tires. I just bought a newer bigger Husqvarna with same tires and it just sits n spins on the slightest hill. I hate it but it looks good and stuff doesnt fall off while mowing. I got these mainly for the yard and not disappointed. They really grip in and will dig ruts like chains if you start spinning. Roll the mower back and forth to get slack out when installing. I put rubber tie downs on which greatly improved fit. I was worried they would start to slide out of place on tires but after a few hours they are still in place. These seem to be good quality, we'll see after a few months of abuse. A bit pricey for me, costs more than my last riding mower I bought at junkyard and used for 10yrs.
