I'm new to road bicycles, sorry if this question is beat to death. What I'm wondering is what to measure as far as frame clearance, rim width, etc. to put the 'widest tires that will fit' on my road bike for durability purposes?
The bike is more or less a glorified BSO, and because of this I can't find any real specifications other than the amazon.com page: http://www.amazon.com/Victory-Vision-Mens-Road-Bike/dp/B002D126EW
The ones that came on it are unmarked, but appear to be 27mm or 28mm, the rim width is 25mm. How do I know whether 32mm or larger will fit before buying them, without rubbing and such?
