I have 34,500 miles on the original Goodyear all-season run flat tires. My tread depth tool shows about 5/32nds of an inch on all the tires. How many more miles do you think I'll get out of them? I also have the original brake pads and the brake wear indicator hasn't yet come on. How many miles does one normally get out of the original brake pads?

E300-18

My tires wore out at 35,500 miles.

This was my first experience with runflats, and I was used to getting about 60K out of tires. Based on a post from @Streamliner , I replaced them with Bridgestone Quiettrack (non-runflat). I'm hoping these do much better.

I'm still on my original brake pads, and they look like they have a fair amount of wear left in them.

Long Islander

60k miles? I've generally gotten around 30k miles from my tires. BTW, what's your plan if you get a flat tire?

E300-18

I bought a spare tire and a jack, which I carried even before replacing the runflats. Not all tire failures are handled by runflats.

How you drive your car will also determine how long your tires last. Tires with long tread life usually do not perform well for spirited driving. Brakes are similar, it varies on the driving, coast to a stop and your brakes will last much longer.

My 2018 E300 (7/2017) is only used in the city and rarely exceeds 40 mph. The factory tires lasted less than 10k miles. My current tires (Pirelli not RF) are about half worn with 6/32" tread remaining. The brakes show little wear and the alignment is correct. The car has 23k miles on it.. FWIW the most miles I have ever gotten on a set of tires is about 20k miles even tires with a 40k mile guarantee. IMO the issue is heat. After driving a mile or so, the tire temps are near 120° F.

I took my 21 AllTerrain in at 40,000 miles for service. My advisor told me I needed new tires so I bought them from him I bought the same Michelan run flats that the car came with. I should have asked him much life my tires had left but I was traveling and I just trusted my advisor. I am sure non run flats are better but the run flats do the job and they give me some degree of protection in the event of a flat. I buy better tires for my 2001 e55 but that car has a spare in the trunk.

After only 27k our front tires looked like we'd run them through a meat grinder. Sidewalls were still great. MB said the road hazard policy didn't cover this.

So I called Goodyear and had them look at the tires. I learned a lot. First, in order for the warrantee to hold, you need to rotate the tires about every 6,000 miles. Second, my local MB dealership doesn't think tire rotation is a part of their normal service, and they failed to ask if I wanted it.

Goodyear, however, offered a deal on replacing 3 of the 4 tires. The 4th had been replaced for a nail just last year. Also, Goodyear will now rotate tires and check alignment for free every 6k miles.

Goodyear Eagle runflats. Front and rear same size.

I find your experience with tires quite surprising. I've never had a set of tires wear out in 10K miles. I've always gotten about 30K miles out of them. This is for both cars that I've driven and for my wife's cars. Perhaps the climate affects wear. I always rotate my tires every 6k miles or so -- that probably helps.

Be aware that rotating tires is not always done when you have different sizes front to rear. What you end up doing is swapping them side to side. Again for different sizes front to rear, You will only swap in a spare of the correct size and wheel if you have it in the trunk. Trunk isnt big enough for 2 different size spares.

What you can do is get the car alignment checked once a year and brought back to the middle of any adjustable range. At least you have the least rolling resistance and best braking and tracking for the car.

YMMV

Apologies for jumping in with a W212 E350, non-runflats tires.

The car is just above 96K miles, 2nd set of tires and still material left on the front (5/32), and less on the rear (3/32). The dealer attempted to align it 3 different times within the first 60K miles, and I was never charged, and the service note always said: "within specifications". In any case, a new set in the coming months. Since I stopped taking it to the dealer, the 2nd set has never been rotated.

Still on the original brake pads, but the independent said that I should change them in the next oil service. Nearly 100K miles. Just did the "nail test" on the front rotors, smooth no even a scratch, and barely a lip. Did not check the rears.

Driving habits? The "occasional" (too often for my wife though) spirited run just shy of the speed limiter to the point I could hear the exhaust cracking later in the garage, and the burnt oil smell when I used to use M1 0W40

I can only imagine the tires/brakes durability is strongly correlated to road quality, traffic vs highway ( most of mine), driving habits (like coasting to the stop), and of course tire brand (stock Conti-Contact Pro)

Runflat does not really have any bearings on tread life of a tire but the brand and model sure does. I had Pirelli P7 in both runflat and conventional tires and they both worn out equally fast, less than 20K miles.

Most tires start life at about 10/32". Some a little more, some a little less. You can look up the specs of your specific tire to find the initial tread depth. From there you can extrapolate. Minimum tread depth is 2/32", so you have 3/32" left, which is less than 50%. So assuming everything stays the same and your alignment is still good, with a bit of math you have another 20k miles on these, assuming a starting tread depth of 10/32". Having said that, wet performance of a tire deteriorates the more it is worn as it loses the ability to dispel water. That's largely the whole point of the tread. If you just drive in the dry you'd have more grip with slicks. So dry grip gets better as tread wears down, but wet grip gets worse. I've hydroplaned on tires at 4/32" during the winter rain here, so I only run a tire down to 2/32" in the dry summer and put a new set on before the rainy season starts. With the mostly dry mild climate here I'm on summer performance tires all year round, but I also don't really drive my AMG in the wet.

Interesting. For me Pirelli tires last longer than any other tire that I've purchased. The absolute worst tires are Michelin. I had a set of Pilot Sport A/S that lasted a mere 8k miles. Michelin replaced them at no cost and collected the old set for analysis. The new set, also Pilot Sport A/S, lasted 16k miles - twice as long. My ranking of the brands I've used over the years: 1-Pirelli, 2-Continental, 3-Goodyear and last is Michelin.

The G Man

Funny how everyone has different experience with tires. I have gotten over 50,000 on 4 or 5 sets of Michelins in the pass, horrible experience with Pirelli and Goodyear. Conti is average at best, but still better than Perilli and Goodyear.

In my case, my 2019 E300 came with Pirelli Cinturato P7 Run Flat 245-40-R19. The car is still unde 15k miles and the Pirelli's have become obnoxiously noisy. I have been recommended to go on conventional tires by a friend who has gone through a dozen Mercedes Benz cars (he owns Limousine transport business). He advised me to go with Continental Extremecontact DW6s if I want completely quite and compliant ride and long lasting tread or go with Michelin Pilot Sport 4 All Season tires but said that I should expect only 25k miles treadlife. I have just ordered the Continentals and will report back once I put some miles on it. Pirelli's with 6/32 life left may soon become available on my local Craigslist for sale.

Not to start another debate, but what pressures are you planning to run on your new tires? I do @36psi (cold) all around. Not too low, not too high. It irritates me when I get the car back from service with tires @40+psi. It feels like a basketball bouncing on the highway. I can immediately tell the difference as they warm up to 45psi sometimes.

Long Islander

Thanks, this useful information.

Long Islander

I've had Continental, Michelin and Pirellis on three different cars and they all lasted about 30K miles. I always kept the tire inflated to the manufacturer's recommendations, and rotated them every 6K miles.

superswiss

Yeah, I had same category Pirellis and Michelin on the same exact car in the same exact climate at different times to rule out other variables, and the wear was comparable. Not 30k miles as in my case we are talking max performance summer tires on performance cars with aggressive camber setup. Michelin tires are much better in the wet. The hydroplaning I mentioned above happened when I had the Pirellis on my last car. I never hydroplaned on Michelin tires. Climate plays a big role. A/S tires in Florida for example is probably not a good idea. Too hot.

MBFF2019

My current tires are set at 37 psi for winter. I plan to continue the same pressure on the new tires.

superswiss

Also, the tread wear warranties that Michelin etc offers only apply to square setups with regular front to back rotation. On cars with different size front and rear tires, they all cut the warranty in half. So 30k miles warranty becomes 15k miles on cars that can't rotate the tires.

The G Man

I have the same car and 19” Pirelli tires as you. I am at around 20k miles and has about 4/32 remaining. The P7 tires were noisy when new and gotten worst, runflat’s sidewall tends to make the ride noisier, but the same is true for non-runflat low profile tires because low profile tire’s sidewall is thicker. I will eventually replace all 4 with either the Michelin or Conti tires you posted but in a runflat version. Runflat use to mean very few tire options when it comes to replacements but now that runflat is more popular, there are many nice tires in runflat version. I am a spirited driver and usually get around 25k miles with all season tires. My wife’s car’s tires usually last twice as long. .

For each brand there are a bunch of tire models.
For each model there are many sizes.
For each size there are many speed and load ratings
For each of the above the tread warranty can vary

I do not feel it is correct to say of a certain brand suck as way too many variables.

Same thing with Tire reviews you need to find someone with same tire as much as possible, brand, make, size & ratings.
Then they need to same car.

Otherwise reviews may not apply to you.

That is why once you find a tire you like for your ride stick with it

I have been using Continental ExtremeContact DWS06 tires in my SLK350 since day-1, and swear by these tires for overall quietness, handling/performance, longevity (>25K miles for me) and overall value for the money. In over 120K miles driven on this car, I have replaced these staggered set about 5 times (rears) and 4 times (fronts), hence averaging ~25K worry-free miles per set. This mileage works for me, as the car is a sporty ride and I have a lead foot. My W213 came with Conti ProContact RFs and currently at ~6/32 with ~10K miles added since purchase (~1 year of ownership). When replacement time comes I may just grab a set of my old reliable/favorite tire - Conti's DWS06 non-RFs. If I get about 25K miles out of these, I'll be mighty happy....
