Run them or replace them?

Has that type of wear pattern from the OP (Mrkentee) ever had a cause determined. I've heard of the 'river wear' diagnosis from one of the big name tire companies, and Rawze I've also heard you mention that is a common result of a higher mileage tire wearing on the steer. Do you think that type of aggressive wear on the inside shoulder could be due to a tire slightly out of round? Mrkentee has excellent wear on those steers for the mileage IMO, but would still like to know what the odd wear cause is.


- I have a hair over 100k now on my steers and the inside of one is starting to display that same pattern. One thing I do notice, when I jack up the front end to grease kingpins, I see that the wearing steer tire has a bit of a wobble when compared to the other side (not the rim, just the tire). Wish I could have caught it on the balance machine last year but I didn't. I don't feel it in the steering , yet... I'm wondering if that slight wobble is causing an odd scrub against the road? I'll most likely change them in the 160-175k range unless something happens otherwise as they still have good tread left currently. It's a Toyo M177, so not sure how they stack against others like the Michelin some of you guys run..... I originally had the Brigestones when the truck was purchase, but was a little unnerved about the blow outs on the newest models of those tires, so I decided against them.
