I'm sorry if this isn't the right forum...I'm trying here first though. My moutain bike is on its way out (everything is failing on it and it's a cheap box store bike more than 15 years old). I have a nice touring bike that I ride on the roads. But I occasionally like to ride on a gravel trail. Can you mount wider tires on the same rim or do you have to buy a new rim?
