Run Flat or not???
2019 E450 with 4matic
Should I replace all 4 with standard tires or run flats? Your thoughts and comments are appreciated.
History: CPO that came with Pirelli tires.
Need to replace one, so planning to replace all.
The run flats are a "bit stiff", and the price is a consideration.
Seems Amazon has a spare tire for the car that goes for about $500.
I could get run flats or the "spare tire and standard tires" for about the same price.

I replaced run-flats with standard Pirelli Cinturato and a spare tire, jack and tools several years ago. The ride is noticeably better and quieter. On my next new car I will negotiate with the dealer for standard tires w/spare. They'll probably do it to not lose a sale. I will never have a car with run-flats. My first experience with run-flats was a disaster. The dealer gave me a loaner and MBUSA paid the bill.

I put the jack and tools in the under floor compartment. The spare tire is on the left side of the trunk fastened forward with a bungee cord to keep it in place. I still have room for 2 suitcases and an overnight bag in the trunk.

I'm running with just a tire repair can. I've had a Porsche Cayman for more than a decade and it doesn't have a spare tire either and I've had great luck so I decided to not replace the runflats when the dealer recommended that I replace the tires on my W213.

Storage issue
That is my current question.
I thought the tire would fit under the trunk floor - but wrong.
Yes the jack and supplies would fit there.
I'm going to investigate ua549's suggestion and use a bungee cord.
But - tire storage will lead me to my decision - currently leaning toward run-flats - because of storage.

I agree that trunk storage is a significant down side to carrying a spare.
I was already carrying a spare before I got rid of my run flat tires, because the run flat tires don't address all tire failures. I also only got about 35K miles out of the run flat tires, which I now understand is about normal. I'm used to getting around 60K miles out of regular tires.

If you would be so kind, please post a picture of your trunk.
Just curious about the space remaining in trunk.
In your opinion, could I just take a tire off the car and see how it fits in the trunk?

The car isn't currently available (daughter has it on vacation) so I can't take a pic, sorry.
You can use your own tire for fit. My car tires are 245/45R18.
The spare is a compact spare 135/70-19, MB part 213-400-06-00.
It has the same rolling radius 245/45R18 but it is not as wide.

I bought a donut spare for my wagon. But don't usually carry it. If I'm going on a long trip through the middle of nowhere, I'll stick it in the back. I just put Continental Pro Contact LS tires on the car and it is noticeably quieter than it was with the Michelin CrossClimate2 tires that it previously had on it. I'll use the CC2s for winter tires.
I haven't had a flat tire since 2005. Maybe I'm jinxing myself, but based on where I drive (not in a city), I'm not concerned.

BTW, I thought I read that a reviewer said the CrossClimate2 tires had some built in tire protection but that they weren't actually "run flats". Is that correct? If I hadn't seen the PZ4s on sale for practically free I was planning to get the CrossClimate2s.
You said they are quieter. How does the ride compare between CC@ and the Pro Contacts?

My last flat was in 2009 in the Porsche on I-10 heading to Tallahassee. Ran over something near Gulfport with the back tire and immediately the TPMS sensor went off. Drove to the first exit and there was a car dealership. They fixed the tire for 40 bucks.

The Continentals ride great. I'm not looking for performance, I'm looking for quiet and comfort and they deliver that in spades.

If I could piggyback on this topic, does switching off of run flat tires affect the recommended tire pressure? I'm not sure if the Mercedes recommendation for my car is the same with a different technology of tire vs. the original equipment.
When I bought new tires (Bridgestone Quiettrack), they put considerably more pressure in them than the 32 psi that is recommended inside the gas cap, but it's well under the max pressure for the tire. I haven't been in a big hurry to reduce the pressure, and I'm not even sure that I should.
The Bridgestone website also didn't seem to recommend a value. It states that the ideal tire pressure depends on the vehicle.

I don't know why but after almost every service my dealer increases the tire pressure to 38 lbs. If I didn't know better I would think he was trying to wear at the tires faster. Thing is with the runflats I liked the ride better but my OCD has always caused me to lower the temp back within a couple days.

Two things.
First, I had the PZ4'S, if all you need is a front, they are on sale at Tire Rack for $141 bucks.
Second, I've just replaced with Continental DWS06, there's a post on that here. For me it's a game of probability and time. For me, the run flats ruin everything about the car with the possible exception of peak grip although I have not run top rung non run flats on it. They do this 100% of the time. Without getting into all of it which is covered elsewhere, the issues associated with towing/flats/tire repair don't really favor run flats in my opinion. The question is, run a small likelihood of inconvenience due to a flat or ruin the car all the time.

But, with the run-flat, I now have a 'bubble' on the front right sidewall. So all four will be replaced. This is the time to make a decision. The tire dealer suggested I change to 18 inch rims.

As luck would have it, I recently got a nail, which caused by (dealer installed) run-flats to "do their job", and I drove the 40 miles to the local tire dealer I prefer. The tire was patched and I'm running fine.

Just a suggestion: I too have had to replace my Pirelle Cinturato P7 RF, with plenty of tread life left because of sidewall bubbles. I have the standard 18 inch wheels.
When it comes time to replace my tires I will have it done at Costco: Costco gives you a 5 year road hazard warranty. In the event there is once again a sidewall bubble, it will be covered by the 5 warranty.

On tire pressure...
My guy, who has been wrenching on M-Bs and BMWs for close to 30 years, says to use the recommended pressure on the driver's door sill, not the gas cap. Not sure why they're different but they are on my 2017 E400 wagon. He said one of the reasons the AMG wheels were bent (when I bought the car) was because the tire pressure was likely set too low. I keep mine at 38 front, 42 rear per the door sill plate even when I'm not carrying anything in the car.

I purchase regular tires.
Firestone SureDrive (Store brand)
Looking at this as a 'test'. I personally don't notice the difference in ride smoothness. But it may just be me.
If I experience pain (flat tire with trauma) then I will return to Run Flats.
With about 2,000 miles on them; things are going well so far.
Thanks for teh help and suggestions.
