Tire tread wear.
Is it normal for tires on a 5'ver to wear evenly across all threads. Or, because of scuffing and being ST's will the outside threads wear faster then the center. Giving a slight "football" appearance.

The only time I have had abnormal wear on a 5th wheel ST tire was from a bent axle. I run 80 PSI in E rated tires.
