Agree with Buildit though I normally ran 36-40 depending on load. I recently started running the Distanzia and it is a great road tire. I run teh same air pressures as the Gripster though get about the same road mileage.
I would love to find a rear tire that gets 8,000 miles before replacement. I recently heard of a Distanzia that had good tread left after 15,000 miles. It could be true and I could be good looking and wealthy but we know that is not true.
For off-road I am going to the newish Michelin T63 which I have heard good things about. I have heard better but would like 6,000 out of the rear tire. i am going to test a pair in CA before taking them to D2D for a 10,000 mile trip followed by a week in Southern Oregon.
End result I run 32-36 front and 36-40 rear.
