what tires should i get for my quad? i have the ITP mudlites on here now but the rear ones have the side lugs tearing off and they are only 4 years old? they are 6 ply by the way. im looking for a softer riding tire that is decent in mud and more for trail riding with occasional mud holes and muck. once again like a 2 ply tire would be nice. would the duro mud and sand tire be good.i se them on alot of trikes. any suggestions would be appreciated thanks!
