Tire Wear Question

[thd]

I have a Seismic 355W and I picked it up from storage today. I was underneath just checking stuff and notice cupping on the edge of my tires. Both sides. Left front is the worst, with significant cupping inside and out. Tires are G rated and inflated to 110psi, always run max pressure.

What causes cupping on both inside and outside edges of the tire? Alignment issue?

I also started using a TPMS and was wondering what the max pressure alarm should be?
I set the alarm for 130 psi, and when the outside temp was above 90 degrees, the tires would exceed 130 psi. Is this normal?

Possible alignment or bent axle


Use a straight edge against front/rear tires and measure gap at front edge VS gap at rear edge
