I'm mostly shocked at how extreme the effect was given the small wheel radius difference. Driving the car at 70+ was incredibly annoying. Constantly corrections needed. On and off the gas created a zig-zag effect.

With one tire at 34psi and the other at 38 the effect is still there but to a smaller degree.

The larger wheel is putting down more torque so it will wear down... it's just a question of how long it takes.
