Hello out there.
I'm slowly building up a sort of MTB thingy from variously-acquired bits. The wheels I have are 17-559, i.e., 26 inch wheels with an inner rim size of 17mm. My LBS assures me that these rims will happily work with 2.1 inch tyres. Now I've fitted such tyres to the rims and inflated them to the recommended pressure and they certainly work in that the tyres stay on the rims and look quite comfortable (in a fat, bloated sort of way) at least while the wheels are merely sitting in the shed.
Thing is, will they actually do the job when the bike is up and running? Does anybody have experience of using such a combination? For all I know, every mountain bike on the planet is equipped thus, for my ignorance of the type is broad and deep.
Any advice or experiences most welcome.
Brian
