I am trying to salvage an old road bike. When I received it the tires were flat and crumbly. I purchased new tubes and tires today. They match the wheel and the tires that came off. But now fully inflated they don't fit the frame. The tire hits the bar that holds the brake. Can tires vary this much even if the are the same size or do I have a bigger problem? Anything I can do?
It's a Univega Vivatech, 700 x 25c wheels, vertical dropouts, Armadillo tires.
