I've been experiencing extreme tire wear from regular daily driving my 450+ SUV on SoCal roads with the original Goodyear Eagle F1 on the purchased car and replacement Eagle Touring Runflats.
The original 275/45R21 F1 fronts lasted 15,000 miles. The original F1 285 rears lasted only 7500 miles and the replacement Touring 275's lasted 7500 miles as well.
I changed the rear size to match the front because I wanted to be able to rotate them, but they wore out so fast I didn't get a chance to. Has anyone else experienced this?
I also have the original Goodyear Eagle F1 Series 5 tires on my 2023 580 SUV with 6K miles and with my “average” driving style have 6/32” on the fronts and 5/32” on the rear set. I have no idea the original tread depth but doubt I’ll get 15k miles out of the four. I’ve owned dozens of vehicles over the years from some sporty SL550’s to my F250 trucks and have never seen this much wear on tires this fast. When the time comes I may go to my favorite Michelin Sport tires if available for 21” rims which are not made specifically for EV’s though I must admit these Goodyear’s are whisper quiet and provide a very smooth ride.
At 6,200 pounds, I expect I'll be buying new tires often. My car (which someone else ordered) came with summer tires. Any thoughts from owners with all-season tires?

either your driving is too aggressive or your car needs alignment
I am also in SoCal, 580 7 seats, currently 5979mi, Pirelli Scorpion 275/21 285/21. both front and rear are reading 8.4/32 as now. I think brand new is 9/32. but my driving style is very mild. I can use Pirelli trofeo r 325/19 for 5000 mi and it is only rated 3000mi.
My EQS 450 4Matic SUV was equipped with 275/45R-21 Goodyear Eagle Touring RunOnFlats. I currently have just under 17K miles on the tires and I will get between 20K and 24K miles on this first set. I rotated them at 6K and 15K miles. I plan to rotate the next set of tires every 5K miles since the passenger side and rear tires are wearing faster. If I had not rotated the tires at all, the passenger side rear tire would be finished before 15K miles.
My next set are 265/50R-20 PIRELLI SCORPION AS PLUS 3 XL. These tires start out with a 11/32" deep tread. They are not EV specific, but TireRack does not offer EV tires in this size.
Not to belabor how heavy the EQS SUV's are, but I wonder if replacing the OEM tires with tires not specifically designed for this much weight could be dangerous. The sidewalls of the OEM tires selected by MB surely were reinforced for this weight. Anyone know for sure if specific OEM tires should be used?
Cannot answer your question but the Pirelli’s mentioned above and the Michelin Pilot Sport All Season 4 are made for SUVs. Some of us will have to make a decision later on this year and the EV specific Goodyears on my 580 SUV are not listed on the major tire retailers yet so what is one to do?
The current largest IC 2023 Chevy Suburban has a gross weight of 7,700 pounds.

The 265/50R-20 PIRELLI SCORPION AS PLUS 3 XL tires have a higher capacity rating and higher speed rating than the Goodyear Eagle Touring tires. I don't expect any improvement in range with the 20" tires since the tread width is the same on both tires, 8.9" and the 20" tires have a higher revs per mile since they are slightly smaller in diameter.

each tire has max loading rate, as long as all 4 tires total max loading rate is over your vehicle max loading rate you will be fine. said like our EQS SUV is 8000LB (I dont remember but should be close), each tire should be at least 2000LB but better be something over 2000LB. also remember our EQS SUV is not really 8000LB. it read the MAX LOAD which is with 5 or 7 people on the car with all the luggages. the actual weight of the car is max load - load weigh = actual wet weight

I believe there still some shortage on tire so most the OE tire goes direct to car manufacturer. not a lot of extra goes to market for consumer to buy
OE tire is car manufacturer specially design for this and only this vehicle. they add some of their own design vs tire manufacturer standard design to make it more sticky, or comfort, or quite whatever they want for this model of car.
it is like someone give tire manufacturer a design and ask them to make it.

vehicle weight really does not effect tire wear per se.
I mean look at heavy pickups their tires can last long time - mine regularly gos over 50K and weighs over 6000 pounds.
Things that affect tire life the most (no particular order)
Tire rubber compound
Driving habits
Roadway surface texture and material
Vehicle tire Alignment (Toe & Camber)
Vehicle suspension
Overall Tire/wheel Balance
as for load capacity simple get the same SPEC tire as OEM tire.
Tires come with a load capacity in the model code
Fron tire spec I got from Tire Rack:
275/45R21 110H XL
the 110 is load capacity and the XL means Extra Load capacity.
Go to this tire spec and you see 110 XL means 2337lbs capacity per tire @ Max PSI.
Tire Rack is nice enough to put that info under a popup when you click question mark near this number on page.
Rears = 285/45R21 113H XL - 113 XL is 2535 lbs
Actual tire load capacity at lesser tire air pressures is done by ratioing actual pressure w/tire listed max pressure and mulitply by capacity.
Example:
Air pressure max on tire =50PSI
MB door jamb sticker says fill to 36psi
Actual front tire capacity = 2337 * 36/50 = 1683lbs
Just make sure you have the same load capacity spec as OEM tires and you are god to go.
Note some tire manufacturers may have more then oad capcity tire rating for the same model and size tire.
You will see this in the code.
As always Tire Rack is your friend for researching tires.
Yes the EQS SUV is a heavy vehicle and the very crux of the issue is not so much looking for / researching different tire brands!
But the fact (other then tire rotation) OEM THERE IS NO FRONT OR REAR WHEEL ALIGNMENT ALLOWING TO ADJUST “CAMBER” (TIRE CONTACT ANGLES) TO SPREAD LOAD MORE EVENLY TO RESOLVE, COSTLY PREMATURE TIRE WEAR / REPLACEMENT.
TO CATER FOR OTHER THEN “SHOWROOM HEIGHT” CONDITIONS ENCOUNTERED IN DAY TO DAY COMMUTING.
....high cambered roads with excess passenger side edge wear. Wheel squat through load carrying or lowering. Fitting wide profile tires or simply having ongoing adjustment capability for curb knock damage.
Then seeking out and being quoted (reassuringly) - “WILL CARRY OUT A FULL FRONT & REAR ‘4’ WHEEL ALIGNMENT”
WHEN IN ACTUAL FACT - all that can be adjusted OEM now is basic / single Toe - “directional adjustment” !
New car industry’s best kept secret. It is all to do with cost cutting and ever increasing speed of new car assembly lines.
Then the frustration of being told “cannot resolve these issues” and with the only possible excuse (to try and placate) - “That it is within factory specs” !
FOR THE EQS SUV WE SAW THE NEED THEREFORE TO FIX IT RIGHT THE 1ST TIMEAND REINSTATE BOTH FRONT CAMBER (AND CASTER) ALONG WITH REAR CAMBER (AND EXTRA TOE) ADJUSTMENT.

Just rambling,............I've a EQS 450 rear wheel drive sedan. Rear tires were Bald at around 19K miles. I'm over 80 and not a 'hot rodder'. I am of the opinion that if I had a 4Matic, then all four tires would drive the car off a stop light and the wear would be more even and my rear tires would not have been bald at 19K miles.
Note: I had to get the new rears from my Mercedes dealer because I could not get them from Tire Discount or other places. I own two other Mercedes with 4Matic and the tires wear evenly imho. Plus past CL550 with 4Matic did not wear the rear tires out like this EQS 450 sedan.

On the 4 Matic all four wheels are not powered at the same time so the tire wear is not even. On my 580 SUV under normal acceleration the front motor is used until around 35 mph and then it shuts off and the rear motor takes over at higher speeds. Both motors are only used during quicker acceleration. My rear tires are wearing twice as fast as the front tires. There is a screen on the 580 SUV where you can watch which motor, one or both, are in use at different speeds.
At the 18000 mile mark I find myself regretting that I did not rotate the non-staggered tires more often. I am estimating that the average rate of wear was between 3000 and 3600 miles per 1/32" of tire tread. This translates to between 21000 and 25200 miles for the life of a set of tires provided that you are willing to run the tires down to 3/32" of tread.
If you don't rotate the tires, expect the right rear tire to wear out much sooner than the other three tires. I rotated the tires front to back at 6000 miles and in an "X" pattern at 15000 miles. I charted the position of the tires and the number of miles at that position and compared the remaining tread at 18000 miles.
Observations: 1) All tires wore evenly across the tire. No excessive inner or outer edge wear. 2) Tire #1 with 1/2 of total mileage in Right Rear position exhibited highest wear. 3) Tire #2 with 1/2 of total mileage in Front Left position had least amount of wear.
I am planning to rotate the next set of tires in an "X" pattern every 3000 to 4000 miles in order to maximize the life of the set of four tires. I decided to decrease the mileage between tire rotations so that each tire is in all four positions every 12000 to 16000 miles. If I had staggered tires on the car, I would rotate them side-to-side on the same schedule.
Edit: Upon further reflection I realized rotating the tires in an "X" pattern won't result in positioning each tire in every position after four cycles. However, since the RR experiences the highest wear, the FL exhibits the least wear, and the FR and RL wear about equally, the "X" pattern rotation may still be okay.
I realize that this thread is several months old. Wondering how tire wear has progressed for you guys?
I'm on a 24 month lease, 15K miles per year. It seems like I'll have to swap the tires out at least once during the life of the lease in order to return the car with acceptable tread life left.
Are there any options that will last longer than the stock Goodyear F1 tires?

I got to 24K miles on the factory installed 21" Goodyear Eagle Touring RunOnFlats before changing to 20" wheels. I plan on changing back to the 21" Tires next Summer to try to get the last 1/32" of tread depth out of them.
