Yes, I noticed that also. Tractor tires are designed to work the mud out from under the tire to get to solid ground. When they are on back wards it works it under the tire to the center. That lifts the tire giving less traction. There may be a reason we are missing. Front or backwards it's got to be a big smile factor. I'm, for now, setting my bike for sand only. His stock wheel will be a 10". He is offering the 12" wheel, as an option with the tractor tire. From the video it looks to be real fun.
Having worked in the auto restoration industry for years I have developed a critical eye for detail. It does not matter how cool I make my bikes look or run. My eye goes to the off centered rear fender or the microscopic dent in the pipe. It's kind of a compulsion. Man a new ban. No talk of religion, politics' or MENTAL ISSUES.
In no way am I an expert but I did stay at a Holiday Inn Express last night.
