I have been using generic brand tires for a few years.About $20.00 per tire. For some time now i get a flat about every 3 weeks (average 6-8 hours riding a week) and hate it. Used generics for along time and it was ok. Not lately. I use an older Schwinn 12 speed road bike with 27-1 1/4 tire/tube size. Can someone recommend some brands of this type that are more durable and more puncture resistant and what price range i should expect? Thanks
