This is 70k on a 50k tire adjusting air to suite the current load. 5k rotations. 65-80psi front 50-80 rear first # was my empty seting 2nd is an up to based on load weight balance.

No funny business it is ~ 20k mi extra wear in the centers.

I ran the air at 80 front (sidewall max/recommend psi) and only the centers were part of the contact patch. Shows here.

100mi @70mph @80psi on 3800lbs front.
And more obvious on the rear @70psi 3000lbs

Notice the mold injection tits are warn off completely yet the sholder block tits on both sides are intact , shows what is touching the road with how much froce/heat generation . The sholder tapers rabidly as indacated by the verried leangth of the tits , shortest were the closest to contact closer to the center tread. The color also shows the transition from contact to Airborne.
