i run nothing but fast trekkers. they are cheap and go good on hard pack and mud. i run the fronts also and they have a good contact patch. they turn really good and such. id say try a set, only problem is that i dont know if youll find a set anywhere now. i think they are either shutting down the company or they are switching manufacturers. someone might know more about this than me. but id say if u can get ur hands on some then go for it. oh yea get 20 inchers, not 18s unless ur racing motocross.
