I have a MPV front tire on my 2010Goldwing /champion trike put it on at about 6K miles in 2012 now have over 21k miles on it and had to replace it due to extream cupping after a short ride this weekend. I keep a close watch on tire presure and I do use the front brakes with the back brakes to make smooth stops. well here is the deal it went from a good looking front tire to a "oh my gosh this tire is trash" with in just a couple hundred mile at speed around 75 mph and bursts up to 80 all interstate riding. Has any one had this issue with the MPV running 41 PSI ?
