I currently have the TW 32 rear tire for my TW. Its the knobbier stock tire. Newer TW's come with the TW34 which is similar but not as aggressive. My question is, who has had the TW 32 and the TW 34 and is the TW 34 a good tire for offroad? I ride 80% dirt and would like the more aggressive tire, but the TW 32 is either very rare or non-existent. I have to have a D.O.T. approved tire, so my options are either the TW 32 or 34.
