Ok after looking at all the cats in the area. There are 7 snow trac/masters within 100 miles of me. 2 of the cats have a 110/90/16 motorcycle tire on the rear tire. And another one has 100/80/16 tires. These are foam filled and have been on the cats for a long time. dot dates are old. They seem to be holding up well. Thoughts? These are a lot more reasonable then the other options I am seeing, at well under 100$ a tire. The tires I can get are a 4ply Whats everyones thoughts?
