Double your pleasure, double your fun....
I changed my DR over to TKCs shortly after I got it, they were pretty good up here in New England for how I used the bike (70/30 ?). When I took the bike down to Florida for winter use (98/2) the coarse pavement really chewed up the rear. I found an inmate who had a set of ProCycle Supermoto wheels/tires that his wife did not fall in love with and made them my "winter wear". They are both 17s, which for me make the handling a little too quick (not the bikes fault, I am old and like to check out the water around every bridge I cross). I have lowered the rear of the bike (factory method) but left the front stock to compensate. When I change back to the 21/17 summer wheels I drop the clamps about an inch on the fork tubes to "level things out".
If I were getting a new set of SM wheels, I would probably go for a 19/17 combination. Certainly less tire choices but the less agressive geometry is a better fit for my needs (and to me looks "better", did I mention that I am old?). This combination of wheels and tires is working out fine for me, short of damage I am not likely to get any more or different wheels - tires, well who knows?
I do have a new T-63 waiting to go on the back for next summer, they suposedly wear a bit longer than the TKCs and that center worn TKC on there now doesn't give me much confidence when I find any mud.
No one calls the Fire Department because they did something smart!
