Avon – Avon Cobra Chrome - Rear - 15 in. Rim, including Cobra Chrome AV92 fitments in 140/90-15, 150/90-15, 170/80-15, 180/70-15 and the wide 230/60-15, plus a white sidewall 170/80-15 for classic-styled builds. Fifteen-inch rear wheels are common on traditional cruisers and softail-style frames, and they carry most of the machine's weight along with the drive torque. That combination is hard on a tire, which is why the AV92 uses a robust bias-belted carcass and a tread arrangement designed to spread contact pressure evenly rather than cupping in the centre. The result on the road is strong straight-line traction off the line, confident grip when the throttle is opened mid-corner, and mileage that holds up under two-up touring loads. Water evacuation channels keep the rear predictable in the rain, and the rounded profile helps the bike transition from upright to leaned without stepping. Pairing it with a matching Avon front keeps handling balanced end to end. These sizes also suit older machines that left the factory on bias-belted rubber, where a modern radial is not an option. Both H and V rated versions appear here.
