4,700 miles on my Model 3 and my tires are on the wear bar

I second this. Mine are wearing faster than my Michelin P85D tires. I have even wear but I'm down to 7/32 front and 4/32 rear with 6,500 miles. I'm driving the 3 just like I did the S. My S tires lasted 20,000 miles.

 

Honest q, how would you have to drive or setup the suspension or rotate to alleviate this so as to keep the tire wear warranty?

 

You can rotate your tires often. You can Zero out the toe and get zero to slight negative camber all around. Zero toe will make the car more lively but also more squirrely while on the freeway. Zero camber will make the car grip a bit less in corners. Both reduce tire wear. I've no idea what the standard settings are or what's adjustable on the M3. Camber probably needs aftermarket parts to adjust.

 

Question to the tire specialists on this board: If the middle tread is wearing faster than the edges, could it be overinflation?

The upside is now you can purchase some better tires.

 

That's overinflation.
Does anyone know the factory alignment spec? Is there toe?

 

You're right about toe but zero camber will make your tires wear faster unless you never turn
You should adjust your camber to keep the wear even between the inside and outside edges.

 

Middle wear: over-inflation
Edge wear, same inner and outer edge: under-inflation
Outer edge wear: too much toe in
Inner edge wear: too much toe out

RWD should come with 265 in the rear, too much power and weight for those poor 235s.

 

7k miles. 44psi. Very even wear. I am careful when cornering; learned my lesson the hard way in the LEAF over the years.
Have yet to find a tire that can run to its warranty mileage when installed on an EV.
I expect to get 20k out of my delivered Model 3 tires; anything more is gravy.

 

I have 48k miles on my stock all season tires on my S 90D. I'll want to replace them before this winter, but there's still enough tread for the summer rains. When I drive it by myself, I tend to drive at 7/10ths. But, I think the dual motors helps keep the wear even, and I am gentle on the tires unless fun is involved.

 

Toe in and out have basically the same effect, accelerated wear. Camber determines whether the inner or outer edge wears.

 

If I was experiencing wear like that I would get an alignment
Don't assume the car is properly aligned from the factory

 

Why is an EV particularly bad on tires? The road and the driver are the same....

 

huge amounts of instant torque at low speeds make it very easy to scrub tread off when accelerating from a stop or low speeds in general.

Worse on a Tesla than a Leaf but still doable in any EV.

 

17.5k miles on my 3, 18” aeros. Have had Tesla rotate the tires twice at recommended mileages. Carrying 41psi since day one, even wear and I’m sitting at about half tire tread. I drive both spiritedly and sedately depending on my mood. Brake via regen 95%+ of the time. Floor it from a stop 10%ish of the time.

 

Saw this earlier this year about tires designed for EVs:

Goodyear unveils new tire for electric cars to reduce wear from powerful instant torque

 

That is one ugly tire, Goodyear.

 

Only got 11k on first set of tires on the 3.. No spirited driving.
There is a service alert for early builds that apparently was causing early tire wear, but I'm not sure hope much it will help

 

uggh, link to the source not electrek
