Avon – Avon Streetrunner AV83, including universal front and rear fitments in 100/80-17, 2.50-17, 2.75-17, 3.00-18 and 90/90-18, dedicated fronts in 2.75-18 and 80/100-17, and rears in 100/90-17 and 130/70-17. Small-displacement commuters, learner bikes and lightweight standards live a hard life in city traffic, and the Streetrunner AV83 is built exactly for that duty cycle. The tread pattern is designed to clear water quickly at the modest speeds where most urban riding happens, giving confident wet grip on painted lines, manhole covers and tram rails. A hard-wearing compound stretches service intervals for riders putting on daily miles, while the light carcass keeps steering effort low so filtering and low-speed balance stay easy. Several sizes are marked front or rear interchangeable, which simplifies replacement on bikes running the same size at both ends. For anyone rebuilding an older commuter or refreshing a small twin, these Avon tires restore predictable handling at a sensible level of tire. Sizes run from narrow 2.50-17 profiles up to a 130/70-17 rear, covering a wide spread of small-capacity machines and older imports alike.
