Tire Wear on Outside Edges

[joaquin45]

I have a 3270RS with Sailun "G" rated tires. I have about 12000 miles on the unit and back about 500 miles or so ago I noticed pretty good wear starting on the outside edges on all tires both axles. Tire pressure is as what came from dealer (~102 PSI).

Anyone have experienced this problem or a answer to what may be going on?

Thanks,

Raise the pressure to 110 psi on all the tires

Joaquin, just to verify, you have 12,000 miles on your 2016?
We have maybe 5000 miles on our 2015 and noticed wear on the outside edge of the front right and left rear, which I believe is caused by the "correct track" being out of adjustment. That's on the maintenance list for the next visit to the shop.

Fwiw, I had Goodyear G614 on our previous sob, and had the same issue... as did most.
We will came to the conclusion that the wear is a result of tire and road forces from turning etc. After 30,000+ miles it remained a non issue. I expect the same from the Sailum.

Just to clarify...it was all four tires on inside and outside edges. Wear like Bourbon has is perhaps a different animal.

If your tire wears on the outside and inside that is an indication of under-inflation. If your tire wears on the middle that is an indication of over-inflation. The G614 inflation should be 110 psi cold. It is under-inflated at 102 psi cold.

One thing to consider on tire wear on heavy vehicles. If you travel roads that have quite a bit of crown to them. Your right side tires will wear more than the drivers side. This is due to the TV and trailer are trying to push themselves up hill all the time. Don't believe me, ask any trucker about this and I was one for period of time. The right side drive tires wore out almost twice as fast as the drivers side.

Over or under tire inflation will cause abnormal tire wear.
