While that chart you linked too is for 'steer tires', it is somewhat applicable to all,,, somewhat.

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?

imo, the wear you're talking about "cupping inside and out" is caused by tire/wheel/hub out of balance, out of round. Probably a lot out of balance. A very loose wheel bearing will also cause this type tire wear.

An hot to cold increase from 110psi to "the tires would exceed 130 psi" seems excessive to me.
iirr, 5-10psi increase from hot to cool is normal for my 80psi e rated tires in normal driving conditions.

If your tire is getting a constant bounce or scrub while driving, that may heat it up enough to make a 20+psi increase..?
If you fill tires with an inert gas instead of air, you will in theory get less increase.
