I have a craftsman riding mower and I keep having issues with the front tires breaking free from the axle at the hub. I have replaced the tires twice. Each time proving to solve the issues a couple months and back to square one. Now I'm thinking the issue is not the tires but maybe the tire issue is the result of a different issue. Help! I bought a craftmans because the name stands for quality... no?

What type of surfaces do you ride this over? Sounds like they are getting hammered pretty good. Also what Model tractor is this. Craftsman has and does make a variety.
