What style of riding do you need them for? I absolutely love my Deliums because of the aggressive tread and wear like a tank. But they're a very heavy tire. When I got my first set I thought they'd sent me motorcycle tires by mistake. But no more spin outs on climbs. Wheelies yes, spin outs no. I paid about $15./tire with free shipping on the bay.
I should add that I'm switching to Wardens this summer only because I picked up a pair brand new on the bay for $17. total w/free shipping. Couldn't pass them up and was shocked when I won the auction. Very aggressive tread pattern. Did I mention that I like aggressive tread?
