Hey Sirrus friends! I recently picked up a 2014 Sirrus Sport Disc that has 700x28 Nimbus tires. As a beginner rider I'm pretty untrusting of how narrow they are for taking them off pavement. As I get better at riding, are these tires appropriate for gravel? If not, can you recommend some specific tires for me to look into that would be good on pavement and gravel?
