This is my second set of Bear Claw's which tells you already what I generally think abut this tire. I went through the typical debate over bias vs radial and decided that the weight savings + cost savings was enough for me to go bias. This set is on my 2011 grizzly and the previous is on a 2007 Sportsman. I use them all year long having deep snow starting in November switching to trail/off trail in April. The ride does have a little vibration due to the aggressive tread, but when you are off road it isnt really noticeable. The grip is much improved over the stock tires. Since I havent used any other non stock tires I cant say how they stack up against them. Regarding wear, I cant say just yet as I havent logged a significant amount of miles on the Sportsman yet and my Grizzly is my ride of choice.
Overall my early experience is favorable and the price from Motosport just cant be beat. I would recommend this product be purchased from this vendor.
