Hi, I installed these on my 505-19 JCB. They work great and I got a great price! I have sandy soil around my property, and these did track very well. Tractors are known to get stuck in the sand, pushing things around, like trees.

Good tire. I haven't had any problems

I've got these on my old Skytrak 6036. They look skinny and they tear up the ground compared to the old wider tires of the same size. It looks funny straight on like it's on pizza cutters, but man do the tires work great! They are smooth-ish on the road in 3rd gear. They grip through mud, snow, etc just awesome. They seem to wear a little faster, but within acceptable limits. They're noisy on concrete. They're quiet-ish going down the road. They hold air great and they are inflatable up to like 40psi instead of 35psi which is the standard. This makes for better stability when lifting loads and less tire squish like you get with foam filled or more wide conventional grader / handler tires.
