Tire won't come off - frustrating...
I have a new one (for me at least). Have bought new wheels, 700c's, mounted tubes and tires (the front one a little tight though), to discover that the front tube was leaking. I wanted to change the tube, but I cannot get the freakin' tire off the rim. I have broken 3 tire levers now (plastic ones). I have removed tires lots of times before - but this time I am at my wits ends. Usually I put one lever in, use another one to pull around the rim - and the tire is off - well not this time apparently.
Anyone with a good suggestion?
