I don't know what pressure you were running in the G. Two up and one up 45 seems great to me and I drag the pegs frequently one up. I just put the Alpin on and got a short ride in weekend before last. I'm at 42 and I'm going to 40. Its a little harsh riding at 42. I've been riding the front at 40 also. May end up at 40 for both ends. That runflat is stiff. Sidewall feels three times thicker. It us two plies vs one ply on the G. Weather has been too bad for a good ride.
