I bought a set of these for my Deutz Allis 1920 which is a heavy duty garden tractor and have been very pleased. They worked great in the snow on fairly level driveway without chains and can go on the grass without tearing it up. I can even use my steering brakes for tight (15") turns on dry grass without damage. IF you have a machine with 12" rims that can handle the 26" diameter, these seem to be the best all around tires out there. I have used lawn tractors but this is my first heavy duty machine and looked around at everything before settling on these. I got them filled with Rim guard for extra weight when using attachments like snowplow, snowblower, tiller, and moldboard plow. I have never gotten stuck and barely touch the differential lock which is night and day from using the turf savers that it came with. The only problem I had was ordering them, and two different online orders I placed were unable to be filled, but I contacted a local Carlisle dealer and he was able to sort out the order with his supplier. I think because they are a new item, not everyone has the stock codes correct.
