Thanks for the post. I have watched these videos before and they didn’t convince me the R14 is better than the R4 except possibly in hard surface situations which I don’t get into very often and possibly muddy situations which I also don’t have much of unless I’m tearing up the property. I have no plans in tearing it up. One of the videos seems like he was trying to promote the bar turf tire. I appreciate your input on the subject.Messicks made some videos on the R14, including a video R14 vs R4
