I think there are two variables contributing to the different experiences. 1. Alignment ex: factory which will be in an acceptable range, but not necessarily fixed. 2. Driving behaviors. If I drove in standard all the time I think my inner rear tire wear would have been much less pronounced. Because I’m generally always on freeways over 65mph, and the car defaulting to low, I don’t think my rear tires stood a chance.

Caution Model X, Hidden Tire Wear

So this is also an interesting point. Does anybody know what mode the car is aligned in? A car that is dialed in for standard, but is driven in very low or low is going to have substantially different alignment values.
On another thread talking about the front axles breaking on the MX and another member posted this video (
) which is pretty recent - April 2021. The tech explains much of what's being discussed on this thread in the first 5 mins. I found it to be pretty helpful. Not sure how good the product offered in the video is (looks like it's brand new) but will be interesting to follow or hear from folks who have installed them.
Not sure it will make much difference since neither rear toe, or rear camber is adjustable unless you have replaced factory links with aftermarket adjustable links.
Any idea how much (or how little) this affects your efficiency at freeway speeds? I don't lower until 65, but I'm thinking maybe I should turn automatic lowering off for the same reason.
If you're running the OEM Conti's, that might not be good enough, mine were showing belt in one spot and looked fine the rest of the way around, so the odds of me seeing it before I felt vibration from the belt were slim to none. I've not seen that kind of uneven wear around a tire before, so I assume the OEMs are just excessively cheap and I'm on Conti DSW's now. I'll probably still inspect them all around every time I change to my winter tires, but I don't expect to see that again.

Gee this thread is interesting. Is this a new issue with newer MX? Reason I ask is because one of my cars is a late 2016 MX and I have never had this issue. All 4 tires wear perfectly evenly.

Still Trying to Figure This All Out
Mine's a very early 2016 and it has the issue.
BTW I set my lowering speed to 65 from 55 and I am not confident it made any difference. I am now at 23,000 miles and may not make it to 28,000 like I did the first pair.

That's good info. I wonder if the suspension lowering speed is some of the difference. I have mine set at 90 mph so that it practically never lowers. My first set of tires got about 27,000 miles with even wear and I still had some level tread left.
Good info here. My strategy is:
1) new Continental dws06 plus tires on 20s from America's Tire
2) always be on standard ride height, even freeways
3) get alignment at Tesla service center in standard height.
Hopefully tires will wear closer to even. Will pay extra charging on a trip, maybe $5, for using standard height instead of low.

I leave my ride height at standard hoping it would help, but after 25K miles the insides are worn down on my DWS06 so will be replacing soon. I'm not sure if an alignment would help as 25K seems to be about the average for tires on the X.
Thanks for the info, does your suspension lower at freeway speeds? I set mine to "never".
I was worn down to 6/32, evenly on all tires at 33,000 miles. I could have easily made it to 40,000, except for a 6-inch gash provided by a tire seeking brick. I run in low all the time. Good wheel alignment is critical.
Mine is set to never, but I think I am going to change it back as I haven't really noticed much of a difference. Although wonder if it will help with the longevity of my air suspension since it won't be going up and down as much. Just went past my warranty, still debating if extended warranty is worth it as I imagine my suspension will be the first thing to go.
Thanks for the info. I don't have that heavy of a foot so I would have thought my tires should last longer. Guess I will go bring it in to get aligned after I get my tires installed. Which tires do you use?
The OEM Continentals. Replacements purchased from Tesla. I have had no problems with them, although I have had the car aligned three times.
