All four of our other car's tires were worn on the inside edge and when I measured the pressures, they were ~5 - 10 psi too low. Would this be the reason for the abnormal wear pattern as well as the poor grip in damp conditions?

The tires are some Nitto NT500 (or similar junk).

Thanks in advance.

Inside tire wear is usually from an alignment issue. When tires are underinflated the wear on the tires will be on both sides.

Agreed, alignment is your problem. Also check tires for air every month.

Check your toe. Inside edges worn might indicate a toe out situation, particularly with too much camber. You might have real sharp turn-in as well.

The car had some oversteer issues on wet pavement. Would too much camber help or cause that?

I think it's due for a good alignment and properly inflated tires.

Thanks guys!

This sounds like too much toe-out on the rear tyres. Incorrect toe has a greater effect on inside-edge wear than camber. Just try it, use -5 degree camber for a couple of months and check tyre-wear. Then try -5 degrees toe-out or toe-in and see what that does to your tyre-edge wear... in just 1-hour even...
