I have a Gary Fisher Wingra that came with 700x32 tires but I would like to put 700x25 tires on it. I emailed Gary Fisher Bikes and they responded that 700x28 is the smallest they recommended, but I wanted some advice from other hybrid owners that might have the same wheels (matrix 750) and if I might be able to put the 25mm tires on it anyway? Otherwise, would changing wheels to put smaller tires on it be worth it? How much could I expect it to cost? There is something on the front rim that says 622x19, but I don't know what that might indicate, considering fisher said I shouldn't put on thinner than 28mm..
It might be kind of nice to have two sets of wheels, one dedicated to smaller 700x25 and the other at 700x45 or other knobby thick tire that I can take offroad by just switching the wheels. I have read in other posts that the 28 mm might be plenty quick if I get a high pressure one. I am 5'6 and weigh 130 pounds though, so I don't know how important that is, but the 32mm tires do feel a bit sluggish to me currently (rated to 85 lbs)
Any advice is appreciated.
