EV premature tire wear?

Not to repeat what’s already been discussed on the EQS superthread, how’s everyone else’s experience with the tire wear on their EV’s, especially heavier and more powerful ones like Audi GT/RS, BMW iX, i4 M, etc. How many of you are seeing premature tire wear?

EDIT TO CLARIFY: I’M LOOKING FOR ACTUAL DATA POINTS. I.E.: I HAVE XXX EV WITH XXX MILES, MY TIRES ARE XXX AT XXX DEPTH. ORIGINAL, ROTATED, REPLACED AT, ETC. THANKS!

On my 2018 Pacifica PHEV, which isn’t a full EV but has that torque at zero RPM and is certainly heavy, the OEM tires (Nexens) were pretty worn down by 20,000 miles. Replaced them with Michelin Defenders which are doing great at 30k.

EQE 350 suv here, I have about 6.5k miles on mine and the tires are fine and not worn down. I do drive with strong recuperation in the city though, and pretty mild acceleration - don’t usually go over 30-40%.

I have a friend with a Tesla X, he replaces them every 30k miles, but he also drives like a grandma.

My model x tires had to be replaced every 20k miles or so.

Common to need tires replaced at 15-20k miles on higher-performance EVs. I wouldn’t even call it premature wear. It is just natural wear for a car that is producing peak power instantly (and a lot of it) at lower RPMs, which is the area the motor is staying in during normal driving.

My e-golf has 30K+ and still doing fine, 4/32. I think the idea that EV’s will chew up tires is misleading. A lead foot will eat tires, no matter what the engine is.

Heavier cars are going to cause more wear, all else equal

e-Gold is different from the EVs OP mentioned in both weight and performance.

I returned my ex-loaner 530e with over 27K and enough tread to not even have to measure it. Those were OEM Goodyear RFTs.

@wam22 @miserly @Pinhigh27 @MB_Fan You’re all correct and what you’ve stated is conventional wisdom easily applicable to ICE cars. EQS 450+ with all season grand touring tires isn’t a hi-po hotrod and wasn’t expected to need new rubber at 4300 miles. Not sure if you read my other post on the EQS thread but my tires are worn perfectly even and have no other issues. I haven’t had to replace any tires even on sportier cars before 25K. My CLS550 - twin turbo V8 - has 20K on the current tries and is at about same 5-6/32nds as the EQS at 4,300 miles. Both are RWD and it actually takes effort not to chirp tires on the CLS in the sport mode; don’t think I could chirp tires on the EQS even if I wanted to!

I have found limited data here and on MB forums that seem to indicate that EQS SUVs tires tend to last longer than on EQS sedans. That seems to indicate design flaws with the tires themselves on addition to obvious factors such as weight and instant torque from the motor. I’m especially curious to hear from folks with multiple EVs in the household to see if they experience meaningful differences on their vehicles.

Today’s write-up from Motor Trend: a 20K mile update on their long-term F-150 Lightning. That truck weighs nearly 7,000 lbs and has 775 lb-ft of torque. No tire replacement at 20K needed.

Got three data points for you. Each depth is in inches, taken as average of 4 points around the tire.

This is a great article, appreciate the share. A friend has a Lightning and he was rather anxious about the tire wear. Apparently (other issues/frustrations notwithstanding), this isn’t much of a concern on the Lightning. Looks like driving style has a lot to do with it too.

That’s a defective tire or design flaw.

Everyone with this issue should be complaining to MB.

Volvo, for example, tried to blame excess brake wear on usage error but eventually caved under the barrage of customer complaints.

Lightning is running an AT tire with a 115-load rating.
OP has Grand Touring tire with a 105-load rating.
These are not comparable tires. No one would expect them to wear similar.

EV tire wear is well documented and can be easily researched. Most manufacturers are just taking tires developed for ICE vehicles and slapping them on an EV. Not exactly surprising they don’t perform optimally. Using Bridgestone as an example, the most modern tire would be the Turanza EV , not an LS100.

Bridgestone debuts Turanza EV tire optimized for Tesla owners (electrek.co)

Most major brands now have EV specific tires with special formulation to address wear.

My ice sienna eats tires (4500 lbs). We use Michelin Defender 2. It’s rated for 80k miles. It has been good so far. Other people in sienna forum claimed 50k miles usage for this one. You may want to try that for ev.
