Edges of Tread

[HowAboutThis]

I'd just chalk it up as being interesting and move on. It isn't affecting your drive-ability, safety, or even tread life. Even if it is affecting treadlife, over the whole life of the tires you're maybe coming up $5 short. Factoring in parts or an alignment to try to cure something isn't going to even come close in paying for itself.

After this set wears out, try a different brand of tire.

I agree. I just found it so odd to be wearing like that on hers but not mine of the same tire with basically same miles on tires, etc.

I was getting a dealer rotation anyway (so they can fix the wheel studs that break...) so I'll have them check the alignment anyway. It's part of the "free" multipoint inspection.

Got the alignment report. Car is within spec. Sent the alignment report to Michelin for my "case". We'll see what they say. Not looking for new tires unless I have some timeframe that are messed up and unsafe Just thought it was odd. Doesn't really seem like a safety issue from a non-expert's view. Just potentially odd.

Siping doesn't always go all the way down. Tires look worse as they age-- "simpler."

Michelin gave a reply after my message yesterday and said some of their tires go through a phase wear siping transitions into grooves along the edges. This seems to be what Discount Tire also said when I showed them pictures. So it was an oddity. But an engineered oddity LOL
