There's nothing you CAN do, IMHO, on highway driving, to prevent squaring. You're only riding on that small, strip of center tread, hence the wear.
I'd run 38 rear, 36 front and avoid hard accellerations, and if applicable, decellerations by downshifting.
Heat and friction wear tires. Reduce heat on highway use by running a higher PSI and reduce friction by not hammering the throttle, or rear braking by downshifting, or with the rear brake itself.
Factory wants 42 rear/36 front, but that makes me a little hinky too.................
