Urban Bus Tyre
City bus tyre built for kerb contact, constant braking and heavy stop-start duty on a fixed route. Wear is driven by door-side kerbing and stop frequency, not by distance.
Features
- Heavy kerb protection rib on the sidewall, because a service bus touches the kerb at every stop.
- High load capacity at low speed, matching the axle loads of a fully loaded low-floor vehicle.
- Compound formulated for frequent braking and acceleration rather than steady cruising.
- Available in 275/70 R 22.5 and similar low-section sizes used on low-floor chassis.
- External noise class worth specifying where the operator runs early-morning services in residential streets.
