I to decided to tackle the tire change to the new TKC's using only what I carry in the bike. Guess what? It all worked!!! Factory tool kit, two 12 inch tire irons, a little lube, side stand bread breaker, small 12 volt pump.
Glad I did this, sure better learning at home instead of out somewhere along side the trailin the dark. Having the confidence to repair a flat is a good thing.
Milling the rim is NOT nexessary.
