Installed these along with new fronts on my 09 ltz 400. Only have 1 ride on em but they have lots of traction and seem to handle well. I did put a hole in 1 while riding on the railroad tracks, but I'm sure that was my fault. 2 years of riding on the stock tires and not 1 problem then 30 minuets on brand new tires and I put a hole in 1. Bad luck on my part.
