I have a bit of spending money saved up and am adding to the Freedom Machine. I am interested in switching to the Shinko 241, however, I am not super excited about going to a 4" wide tire. I will be replacing the goldenboy in 5.10" and so am reluctant to go to so narrow a tire. Anyhow, here is the criteria. Help me pick a trials tire sold from Rocky Mountain ATV. There are not a ton of choices, but I am super horrible at reading those tire sizes and then guesstimating size. I am willing to buy whatever the general consensus here is and then to try it out and report back. So send in your votes. While we are at it I would take suggestions as to the best heavy duty tire tube. I would prefer to also be able to buy the tube from rmatv. Go!
