Did search already but few clear answers. Anyone try a 120/70/17 front along with 160/70/17 rear tire at the same time. I never liked the stiff 120/60/17 front sidewall and figured the taller 70 series sidewall would also correct the speedometer while softening the ride. Since the 160/70/17 rear would add a little extra rear ride height it would restore the lost front 60 series turn in speed and would give slightly better highway rpms along with a slightly softer ride. At least that's my theory. Any thoughts? I already know it would add slightly more unsprung weight and havent seen any reported clearance issues. These sizes are available in the Bridgestone Bt023 tires.
