I am running the Forte GT2/K 27 x 1 1/8 on my commuter. 950 miles and I've had 2 flats. One was a major gash that took out tube and tire while the other was a piece of wire. The bike lanes and commercial areas I commute through are, in my opinion, a good test of what a tire can take and these are holding up well for me. Plus it's hard to beat the price, especially if you have a Performance store closeby.
