elementary tire question

You would think your front tire rolls slightly more than the
rear tire basically all the time because it makes wider
circles. Why does the rear tire wear out sooner? More weight
on the rear axle?

My bike is rear-wheel-drive.

More weight on the rear wheel, and as the other poster mentioned the
rear wheel is the drive wheel with force being applied which causes
wear. Add to that the rear wheel remains more upright than the front
wheel during tuns so wear occurs in a smaller area on the rear wheel.

This may be a minor factor, but it's there: during braking, the rear wheel
lifts slightly, so there is likely to be more slip, contributing to wear.

I think if you put a cyclometer pickup on both wheels, you would find very
little difference in distance traveled between front and rear.

Perhaps a tiny bit, but as evidence I submit my road bike which almost
never gets it's brakes used, yet clearly has more rear wheel wear.

The front goes farther due to the wobbling necessary to remain
upright.

Here is an in depth discussion:

Yes. And rear tire wear is even more pronounced if you do a lot of
climbing.
