Tire Feathering

[Clutch-n-Throttle]

I just bought a set of Sport Technos for my CS. Great wheels. They came with a set of 275/40-20 Michellin Diamaris 4X4 all the way around. I bought a set of 315/35-20 for the rears. One thing I noticed was that the right rear tire has a peculiar feathering on the inside edge. I did not notice it when the 275 was on the rears. What do you guys think could be the culprit? A deficiency in the tire or is the rear suspension slightly out of alignment. The left rear tire is fine.

Check basic things like tire pressure but I would think the tracking/alignment is out. Where it tire balanced before installation?

Well... I put the right tire on the left and the left on the right. I noticed that the feathering is the same on the left side. It leads me to believe that it my be a problem with the tire it self and not the alignment. WHEW! I do not notice any vibrations on the CS, so it may not be a balancing problem. Double WHEW!

I bought these tires used on eBay. I wanted to see if they were going to work on my CS. I did not want to spend $800 on a set of new rear tires. I bought these for $190 for the set. They had about 50% of tread left. Great price I must say.

I will update the tread if I come across something new.

What I can tell you from my experience is that my Cayenne tires always wear out on the inside edges, and always on the rear tires first. It's not terrible - I got rougly 30K from my second set of tires and 24K from the first set.
