What is the cause of this abnormal tire wear?
We have super singles on the drives... On the rear drives the tires have little chunks out of the tread over the whole tread of the tire. We've maintained tire pressure @ 110psi... We haul 53' refers.
I hope the link works... Picture is much better than words :)
We think we have found out the reason.
The truck has a low-profile fifth wheel. It sets 2" lower than others(measured from pivot point of plate to top of the frame) on some of our older trucks.
There is a couple of loading docks that we deliver and pick up at that have odd angles. When we back in the tires are coming up and hitting the bottom of the trailer.
This explains why it has just started in last month or so, about the time we picked up these new accounts.
Is this a worthwhile discussion?
