Tires , yes always a challenge due to the 15" rim . Have used the Michelin Pilot 4 recently & really like it , but the price is getting kinda ridiculous
Found Bridgestone tire that might be decent . Not sure how long they last . Look for Bridgestone Battlax SC2 . They also make a SC2 Rain model if you ride in wet conditions more .
I found this tire on Ebay for a good price $200 for the rear & $110 front , but not sure what choices you have in Calgary Canada
good luck on tire shopping ...
