Our riding areas are so tight that you quite often have to ride the tree with the wheel to make corners. I've ripped the bottom half of one completely off already. Keep popping the push pins out. Usually one is hanging after a few rides, last time i lost one completely and had to go back a mile to find it lol. I don't ride mud much but do get into puddles... maybe i'll just cut the bottom front off the other side too. The only catch in front of the tire not higher up... plus i'm putting home made rock sliders on shortly, might help.
