Tire wear and fit - the ultimate: get your La-Z-Boy fitted properly, stay off that bicycle seat and tire wear will stay (exactly) equal.

Nobody's quite said this but - rear tires are the drive tires. We transmit power to the road by basically scrubbing the tire on the road. Stopping is the same. Granted, we try to keep the scrub (slippage) to a minimum, both while pedaling and braking (barring those fix gear skidder types) but some scrub happens. More with stronger riders, more with erratic pedalers.

The message? If we want to enjoy the bicycle or simply just get around, live with it - accelerated rear tire wear happens. Wouldn't surprise me if bikes with longer chainstays get more tire wear despite less weight on them simply because you would get more scrub putting the same power into the tire with less weight on it. (I don't see noticeably more front tire wear on my LowRidered and front panniered bikes.)
