I’m getting the 360 radial 36 inch, but I don’t know what tire I should choose. They have two options heres the link -http://www.unicycle.com/shopping/shopexd.asp?id=822
If someone could tell me whats the difference between the two and what they perfer that would be great, thanks.
What link?? 
the Wheel TA tire is perfectly smooth, no tread besides some grooves down the side. The coker tire has a button patterned tread - this may help with traction offroad a little bit but from what I’ve heard it doesn’t make a huge difference. I’ve got a coker tire and I like it all around though I’ve never had a chance to try the wheel ta tire. Theres a bunch of threads you could probably find by searching.
