I just moved out to Michigan for the summer (Lansing Area) and these roads are brutal! I'm averaging a flat every other ride! Granted I'm running some Michelin Lithions, but I never had any trouble back on the beautiful country roads of PA. For those of you from Michigan, shed some advice to the new kid on what kind and size of tires you are running. Also, a question on tire pressures. Is it better to have lower tire pressure and absorb the shock of the road or higher tire pressure to resist against pinch flats?
