Anyone running the Cobra 19" front and 16" rear combo on their Rushmore, any feedback good or bad? My Glide will soon be leaving the nest to rain down it's D & D Fatcat harmony amongst my suburban folk as the weather here is working it's way to Summer. I have been thinking the tires are something I want to replace sometime sooner than later this season. If I am not mistaken, the 19" Avon is a fairly new offering and have not seen any reviews on it so I was curious who has some experience. Thanks peeps!
