14 is350 awd scalloped right rear tire after 14k!?!?!?
on february of 2017 i purchased 4 continental dws06 extreme contact tires from town fair tire and had them instaled with a 4 wheel alignment. all was good until recently. i’ve been having this god awful noise for the last few months and it sounds like the back windows are rolled down and you’re driving fast on the highway(see video). at first i thought it was a wheel bearing so i brought it to lexus and they checked them all and said my right front had excessive play and replaced it. i was like ok great , so it was a wheel bearing and i’m not crazy. on my ride home the noise still persisted so i decided to take it back to townfair who proceeded to tell me that after driving on the tires for 14k miles they are scalloped and not covered under warranty. he also said he can tell i never rotated my tires or got them balanced every 5k and i told him that’s because you can’t rotate tires in a staggered setup. he was very quick to not fix anything and just try and sell me 4 tires even after he repeatedly told me the staggered setup on this car is a poor design but my infiniti had a staggered setup with the same tires and it was fine . i’m so angry right now, i payed almost $1000 for these tires and only got 14k out of them. what are some possible causes of the tires to become scalloped in the rear? afraid that even if i get new tires there is a possibility this will happen again

Same thing happen to my rear, the fronts are good, got 10k out of the rear. Going for an alignment tomorrow with a machine that was just calibrated. I had an alignment done 2 months ago and the tears were good, two months and 4k later they are toast on the inner most one inch, which indicates a toe issue.

here are my updated specs after lexus did the alignment. they showed me the before alignment (the one town fair tire just did) and there was a lot of red and yellow. the tech said they can only do a couple small improvements to increase the tread life slightly

Don't use the machine toe specs. The center point is not the ideal specs.
Request the Lexus specific specs ..
RWD Front: 0 deg (toe in)
AWD Front: 0.05 deg (toe in)
Rear: 0.18 deg (toe in)

Am I understating it correctly, that on that alignment print out posted by r2digital, the rear wheels actually have tow OUT of .24deg instead of needed .18 toe IN (or -0.18 toe out)?
I mean, the small but constant tow out would wear the tires (inner part) very quickly.
It also might explain why I got only 8k out of my rear DWS06s... I have pretty much the same alignment numbers.

- Negative toe is Toe Out.
You always want toe in. When I took my car to a for an alignment (no Lexus), they actually thought positive toe was toe out. So be clear and say 'toe in', instead of 'positive toe'.
Again, see the factory specs I posted above. Most people are not getting enough toe-in in the rear.
The updated alignment above posted 0.11 toe-in, which is still nearly 40% off from 0.18 toe-in. You do not want to short change the toe-in or you can increase the outter tire wear.
