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.

There are probably 15 to 20 threads on this. Suggest you read them and then come to your own conclusion.

Where do you intend on putting the spare and Jack?

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.

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.

Our 2022 E had them from the dealer when you bought the car in January. After 100 miles I replaced them with Michelin tires. Non run flat. . So much smoother now.
