I don't know if Kuhmo's are the quietest but I will tell you that my boyfriend races offroad for Kuhmo and has never had a flat or hardly any extreme wear on his tires and he uses regular street ATs and MTs. With all the open wheel banging and torn off truck parts to run over, they are a tough tire. Before he raced for BF Goodrich and was dropping $125 per race per tire! So I'd give the thumbs up to Kuhmo. ( This is not an ad!)
