I am now running the 13"x5.5 wheels and Winterforce tires that are available at: http://www.ulmerfarmservice.com/otherstuff.htm Prior to that I had the ITP wheels and Carlisle All Trail. I do most of my running on paved roads, dirt and gravel roads, and logging trails in the mountains of West Virginia. I found the Carlisle was very noisy on paved roads and vibrated at about 70kph on paved roads. They were great in heavy mud and on trails. I'd recommend both the tires and wheels from John at Ulmer Farm Service. He is very much up to date on tire options.
