Both outer edges on both tires have worn excessively. The outer rib on both the outer and inner edge of the tire has worn down to wear there is actually a sort of step down. This is happening on both front tires. I run 80 psi in the front which matches usp with Michelin's inflation chart for weight. The Tires are Michelin XRV's 235/80/22.5. My common sence says this is an under inflation issue but again, according to weight it should be spot on. Should I try running higher pressure to correct or at least stop it from getting worse? Is there a name for this type of wear? The tires have 22000 miles on them and are 3 years old. They are perfect in every other way and the rears are wearing really well.
I had a 2004 Newmar MADP and went to Spartan in 2010 with 82,000 miles on my tires...asked Spartan why they were wearing both the inside and outside of each tire...but don't remember if wavy or not....they had a book of every kinda tire wear they had come across...and there it was ...the description said it was normal for mostly high speed over the road driving...i.e. a bus or over the road truck and I typically do a lot of highway driving...Chuck

The area of wear is due to scuffing in that area more than the test.

Castor and camber angles are such to cause the rig to self center and corner well.

Properly done the rig drives nice.

Too aggressive and the rig will center better but wear more.

Toe in is to compensate for tolerance in all parts so as one drives down road tires fall back to straight.

All of these things can cause parts of the tire to scuff on the pavement which may be normal.

Issue is how much is normal and at what point is an adjustment needed.

For peace of mind find a well respected commercial alignment shop and let them eyeball it.

Based on mileage and look they should be able to read the tires and tell you the reasons for the wear.
