I'm sorry, but it sounds more like a solution in search of a problem.

 

As you have set out - your W164 SUV in your case not having the expense of costly, premature tire replacement.

Can assure over last 10 years of producing front and rear Camber adjuster kits for the W164 and W166 you are very fortunate as many owners do encounter “camber change” through above listed situations of other then light loads, non cambered roads.

Then the frustration of learning there is only one factory “showroom height” Camber setting and having therefore to prematurely fund new tires !!

 

Worst case, an extra set of tires might be less expensive less trouble than this “solution”.

 

This is a 167 forum, not 164.
As I posted above, the inside wear doesn't seem to be an issue with the 167.

My 164 inner wear showed up at 33,000 miles, which is a long life for the tires I use and a 5,200# car. I often tow a 27' RV, a bit over GVWR and payload. On cambered roads. Your worst case.

Nowhere near "costly, premature tire replacement."

It's not a swingarm suspension, and there is very little camber change through it's movement.

Even if there were camber change, how could your product eliminate it?
Is it "new math?"

 

Hi - Manufacturing Front and Rear Camber adjuster kits AUDI to VOLVO - trying to keep up with new model releases is hectic.

But over weekend having both front and rear suspensions did find time to check all W164, 166 and current 167 front “arms” re lengths !

All are virtually identical with top arms half length of lower. Hence same Camber change on “W176”. Going on sales, feedback last 10 years there’s certainly demand for both front and rear Camber adjustment for owners that need other then the OEM one offset / showroom height position.

Not only load carrying or being able to adjust resolve passenger side wear through high cambered roads, curb knock damage. Also many owners that do not go “offroad” and lower their vehicles height / roll center for improved handling / safety.


Re your inquiry - Camber change, new math:

Background is we started manufacturing bolt-on Camber adjuster kits back in 1960’s initially for the taxi industry. Premature replacement of tires being a major cost factor.

Then in the 1980’s seriously involved taking on the role of inventing manufacturing for over 40 makes because with the ever increasing “speed of new car assembly lines” - more and more manufacturers deleting adjustment.

With the situation today where the often quoted, reassuring statement “will carry out a Full front and rear alignment” - IS NOW ONLY BASIC TOE “DIRECTIONAL” ADJUSTMENT. The onus back on owners to fund premature tire replacement.

If you check out our website “ABOUT US” - all the major design breakthroughs / Patents last 30 years re adjuster kits have been by K-MAC. Yet a small company / not a corporation funding our own extensive R&D. Also proudly with IN-HOUSE manufacture / not sourcing imports !

AUDI to VOLVO - K-MAC Experience Of Resolving OEM Suspension Shortcomings Since 1964 !

 

I’m having to replace my tires about every 10,000 miles or less. We have around 19000mi on the car and will be buying another set pretty soon. I’ve had Pirrelli and Michelin, the Michelin may last a little longer than the Pirrelli’s but not much. At $3000 a set, this is ridiculous.

 

I have over 28k miles on my 21" staggered Pirellii Scorpion Zero *** and they're good for another few thousand. Do you have Summer tires? If so, you might want to switch to All Seasons.

 

If you have high performance summer tires, depending on your driving style, that kind of wear is not unusual. Especially if you drive the vehicle when temps are below 45°. I had a friend in Maryland with high performance summer tires that he drove in the winter, he actually lost chunks of tread.

 

I have the OEM 20' Bridgestone Alenza 275/50R 20 tires. Run Flat. Don't I "need" to keep using the same tires? I hate them. The tread life is no more than 12.000miles. I do rotate the tires but Front tires chew faster.
Is there a certain Pattern rotation I must choose?
I have seen some 450 using the pirellis and wonder if you just hope wont get a flat tire.
Its a pain for me to keep two set of tires and changing swapping them when I do long trips.
Any advise is greatly appreciated

 

Mine came with a Donut spare ask your dealer or go to Big O tires or whatever shop you use for tires and wheels and get a spare put under cargo area. Or carry a can of fix a flat tire on long trips and have Triple A. Pirelli Zero are the way to go love my second set no issues tried run flats on my GLC 300 never again will I buy run flats give the ride a harsh ride.

 

Thank you very much. A simpler way is always the best way!!

 

I have 21” staggered AS on my 21GLE. Tires still look OK with 46K kms.

 

21 staggered AS just changed out at 33k with 3/32 left.

can someone comment whether the rear tires are supposed to pop out a little bit from the side vs being totally in line to the front tires? From memory before the tire change, I thought the rears were wider out and it was quite obvious before though can’t remember exactly

 

I have original factory Michelin tire since 2020. I have 45,000km on it as of this month. Still have 6/32 tread life left.

 

As BenMB says, get Michelin or Pirelli non-runflats and a space saver spare. If you have third row seating (assume if yours came with runflats) then there is no storage space for the spare, but you can throw it in the cargo area for trips. Your ride quality will improve.

 

I have had my 2024 GLE450Ee for just over a year now. The Bridgestone Alenza Sport A/S 20" Run Flat MO tires have 6600 miles on them. Fronts currently at 7/32 and Rears 5/32. All tires have even wear patterns but will be shot probably before the 10,000 mile mark. I don't drive aggressively but I feel the weight of the plug in battery combined with soft rubber compound has really contributed to poor mileage wear. I'm going to replace them with non run flat non MO in the near future. I've had good results with pirelli scorpion A/S on my previous 2017 GLE350 in the past and might go that route.

 

We leased MB GLE450e 2025 at the end of February 2025. It was frustrating experience the begin with due to salesperson being very vague with everything, we should have walked away from the deal at that time. But here we are in the beginning of August and the car is at the dealership for the last 2 weeks. Around 5k miles the rear tires (Bridgestones 275/50R20 109H) went completely bald, smooth like a skating rink. Very dangerous. Definitely those tires didn't not get this bald suddenly, they were dangerous probably at 4k miles, we just didn't pay attention bc it was a such a new car. Both front tires are like brand new. We contacted the dealership and were told to bring the car in bc of the possible alignment issue. Immediately once arrived we were told that "Oh it's Suv,so the tires wear out faster".As if we never owned SUVs before and so stupid. It's completely ubnormal for rear tires to go completely bald at 4-5k miles while front tires are perfect.Couple of days later we get an inspection report saying alignment is fine, but tires are bald (Duhhhh). What is making them bald,MB?!?! So MB decided to blame it on Bridgestone and contacted them for possible warranty. Bridgestone said that they'd pay for half of cost to replace the rear tires, the rest we have to pay. And all of a sudden MB says :So our battery is placed in the back of the car which makes it bottom heavy and it's expected such a tire wear. How is it normal to go completely bald on rear tires at 4-5k miles? What is the point of the hybrid then? The sale pitch to us was it's a hybrid, you'll save some money on gas and enjoy the experience of a luxury car. Why do we even need a hybrid then, to save some money on gas (which isn't a lot ) but spend thousands of dollars on tires? If rear tires are completely bald at 4-5k miles , that means we'd have to replace them 3 times a year! This is insanity and what's really disheartening MB is acting like their design flaw such as heavy bottom car is now our issue! Not one time during this sale our salesperson mentioned Oh btw you'll save some money on gas , but will have to purchase new tires frequently, we didn't even have an opportunity to make an educated decision whether it's the right car for us. We are very sure this is our last MB car ever. We lost all the trust in this brand. I (as a primary driver) have to mention my style of driving: im not an aggressive driver, my commute to work is 20 min,all paved roads, never dirt road,and I'm always careful since I have my son with me when I have to drive him to school and sports,and I do not pull anything with this car.I feel very unsafe in this car at this point because MB is not giving any certain answers, just speculations why the tires wear out this fast,like maybe it's tires,maybe it's bottom heavy, maybe it's both.We personally think there's a problem with the rear of this car. Changing tires up to 3 times a year is completely insane, making this hybrid completely useless, we'd rather just spend money on gas at this point. As of today 8.13.2025 MB corporate said that there's nothing wrong with my car and it's driving habits (as if I decided all of a sudden to burn through tires after 25 years of driving) and our MB dealership is saying it IS the battery and nothing they can do but to offer the 50% off deal on new Bridgestone tires. If I don't have a definite answer on what is wrong with car, how can I drive it with a piece of mind?!

 

I have 2020 gle 450 have 55,000km (35,000miles) and I am still on the original Michelin primacy tour that came with the car. I think it is more of a driving habit or the type of tires that was placed on the car originally. Go look up the tire rating. The Michelin primacy tour has a UTQG:540AA.

when I had the 2016 GLC300. I had one of the very first ones in town and they had the wrong tires on from factory. I worn the down in 20,000km (12,000 miles). But nothing benz or dealership can do. As there was no requirement or standard of tires rating on any car in this world. They can put the crappiest tire on there and as long as it has the minimum thread. It is ok to sell in Canada.

I average 80,000km (50,000miles ) on any benz factory tires. But the glc was the one off that I ever had.

 

I'm at a little over 28,000 miles on my GLE 450. Front 275/50R20 Michelin Primacy are at 7/32 and rears are at 4/32 (time for replacement). Rotating these tires is more trouble than it is worth due to the different wheel offsets.

 

Yes, you can expect more tire wear with the 450E because of the additional weight.
It's a problem with electric cars in general.
But yours seems really excessive.
Do you keep them inflated to the pressures on the gas flap?

 

This is not my 1st MB, but it is my 1st hybrid and as I am learning now hybrids can be rough on tires. It is my fault for not researching and I wish our salesperson also mentioned something about it. He was selling us a luxury car with an allure of saving money on gas. I don't think it's fair to me though to go buy tires up to 3 times a year, it completely cancels out the hybrid allure for me.
On the way we took the car to dealership, we checked the tire pressure and it was OK, also I never got a warning ⚠️ if there were smth ever wrong. I do not know why I even took a picture of tire temps on that day thinking it was important, but my husband said the temp was OK.
I do not know if you read certain replies of mine but there's an odd thing with our vin. MB corporate is saying it is registered as a Gas car, our MB dealership says No, obviously it is a hybrid. It is probably nothing to worry about, just odd.

 

Lena, there are two separate problems here:

1) Bridgestone Alenza run-flats are bad, bad, bad.

2) MBZ service, apparently, have been told to blame rapid wear on the weight of the vehicle.

As mikapen noted, there is some truth in point 2), but the garbage tires are the main issue. I followed advice here and replaced mine with Pirelli Scorpion Zero A/S (product code 2858100; I have 275/55R19). These are not run-flats. After 18,000 miles, the tires are doing far better than the Bridgestones were at 8,000.

 

It's a gasoline car, not an EV.

What tire pressure do you use?
Are they in line with the gas flap?
Do you, or have you carried a heavy load without adjusting the pressures accordingly?

You won't get a warning from the TPMS system if it's not set to the correct pressure.

 

It makes sense on the vin now, thank you!

The car is at the shop now and I know the tires aren't changed yet so I was able to take a picture from my app. I would like to know what you think of those numbers, I appreciate any help. For a while I was getting some harsh replies, maybe my style of explaining things is terrible, but I'm self taught in English, realizing i may be all over the place. I am a "stupid girl driver" and only came here with my story to see opinions from knowledgeable people who know these cars. I do appreciate all the replies though.
I never pull anything with this car, i only do local driving, 12 miles to work (90% highway), I take my son to school/ sports on local paved roads, never dirt ,I do running around like shopping, appointments, and such,nothing serious. We do not use this car as our out of town car, we take my husband's truck or Toyota Highlander 2019. On the day I took the car to the dealership i took pictures of tire temps, I do not know why , but I guess just in case, but my husband said temps were normal.

 

Those tire pressures seem high. My GLE 450 recommends 32 psi front and back. What are the pressure recommendations on the gas flap. Over inflated tires will definitely wear faster.
