Just did 3000 highway miles on D110X with Duratrac 19”. No noise, vibrations, stiff ride, etc. But did not fly off the Grand Canyon and try to get back up. I think the tire discussions are valid only for the very serious. The tire reviews certainly don’t lead you to any specific direction. PS Got the 19” Duratrac for winter conditions which may help when climate warming dissipates. No doubt the 19’s are selection limiting, particularly if you change your tires based on the weather forecast.
