Has anyone had problems with their predator tires? I've had mine for 1 week and road about 8 hours and my son ran into my second predator and the front tire got cut on the side and flat now. He wasn't even going like 5-10 mph when he hit the predator in front of him. Must have just hit it right, but I think the side of the stock tire is not very good. Has anyone replaced the fron tires yet? I'm thinking since I have to raplce one I'm going to get one Holeshot XCT's 6-ply. Maybe that will hold up better. Anyone have HoleShot tires? and do you like them?
