We just got back from a nine day 3,700 mile trip that took us from TX through OK, KS, CO, NE, SD, WY, MT and back down through WY, CO, NM and back home to TX. The Bridgestone Potenza G019 performed flawlessly! I was beginning to think that the darkside was not for me with only a couple of hundred miles on the tire before we left for the trip but either I adjusted to the tire or it finally scuffed in. The tire was great on the slab and in the twisties! I found that I could really tell no difference in the cornering with the car tire as apposed to the mc tire and I don't think I will ever go back to a mc tire after this!
