Perfect timing on latest posts here. TMC is such a great resource. I had never thought to check the very inside and recently ran across this thread. 'Only' 26000 miles on my 2018 MX. Just did an inspection last Thursday: split and cracked on very inside of multiple tires even though the rest of the tires had quite a bit of tread. Ordered new tires on Thursday, came out to a flat tire on Friday morning before my Friday new tire appointment. Filled it with air to get to Discount Tire: in and out in 45 minutes right at my appointment time. Replaced with the stock Continental 265/45R20 front + 275/45R20 rear tires since they seem to be a good all-around tire. Ended up driving a few hundred miles in fresh snow today so sure was nice to have new all-season tires.

Caution Model X, Hidden Tire Wear
- Thread starter Steinmetz
- Start date
Another happy N2itive customer here. Got it new front shafts installed, took it to EVFixMe and they installed the N2itive parts and got the alignment set on Low. No more shudder, tire wear looks more normal now, drive on Low all the time. Totally worth it.
So I thought I had a nail in my rear tire on my 2019 MX and the guy calls me to say I need two new rear tires as they have belt showing on the inside of both of them. I figured he was trying to jack me up since I only 38k miles on them. My first google search brought me to this thread. I guess the guy isnt lying to me and I also guess getting 38k miles on my rears is better than expected. Time to start doing some more reading on the subject.
Need to get your car aligned at the height in which you drive. If they align the car at ‘high’ it will be out of spec at ‘low’

38K is great for a Model X.
Here’s the reading you need: Eliminate Inner Tire & Premature Half-Shaft Wear On Tesla X/S!
I’ve had rear blowouts twice on my 2017 MX, and Tesla says it’s “normal”. Tire shop didn’t even want to replace the rear tires until Tesla fixes the suspension, which it won’t. It’ll be the last MX I ever buy.
I should note I have only got about 20k miles before blowout occurred (twice). The passenger side each time, it wasn’t quite as bad on the driver side. Still tons of tread on the tire otherwise. Pirelli Scorpion Zero 22’s

Drive in Standard, not Low, and overinflated the tires a bit to semi-mitigate the issue.
But the real fix is to buy the parts from n2itive and that will avoid the tire wear issues *and* the acceleration shudder.

This is a known issue on all model x and s cars running on low setting alters the rear camber causing this to happen. If you raise the car you will cause damage to the front axles. I installed adjustable camber arms on the 2018 mx to correct the camber change this eliminates the inner tire wear. There is a lot of info out there about this issue
It definitely is a known issue. But not everyone is affected. I was lucky with my 2018 100D, tire wear was perfectly even, front and rear. Was good for well over 40,000 miles with factory tires. My 2018 X had many problem, but tire wear was not one of them.

Is this camber issue only on the rear wheels? Or do the fronts wear their inner tread unevenly too?

On my 2016 Model X I had the rear tires inside wear until the radial belts showed and a tire blew out. On my 2019 Model X, both the front and rear tire insides wore out first. Now I have a 2023 Model X and just waiting to see what the problem is going to be. In both the previous cases, the tire life seemed to be about 15,000-18,000 miles.
I don't understand how there are this many tire blowouts and there isn't a NHTSA issue. Like nobody is reporting a blow-out to NHTSA?
Ford Explorers and Firestone tires were a disaster because those blow-outs resulted in rollovers. I guess these Model X blowouts aren't as bad?
Regardless, I feel like a blowout is not the failure condition that ends well for anybody.
