I have a few questions about tires for touring bikes. I am going on the Erie Canal since there will be crushed stone for much of the ride they suggest wide tires with slicks. I have an old diamondback mountain bike that I converted to a touring bike. It presently has full knobby tires. How much easier will the bike run with slick tires?
Second question: the bike has 2.5 inch tires. How much of a thinner tire can I put on the rim?
