I have roughly 15K miles on the original Pirelli P-Zero Run Flat tires. To my surprise they only last about 10-15K miles with pretty bad reviews from tirerack.com. Unfortunately, they are the only run flat tires that the dealer and America's Tires say are compatible with the car. Also, from what I'm hearing, these tires aren't repairable, even if only flat due to a nail in the center.

To me this means the cost is about $1600 from AT or $1800 from a Merc dealership to replace every 8 months or so.

I'm hoping to get more mileage and a smoother ride.

My questions are so...

1: Has anyone tried other brands such as Michelin Super Sport with the Merc C450?

2: If so, did you guys end up using a tire mobility kit to repair flats?

3: Are Tire mobility kits safe for this model car without ruining rims, sensors, etc.?

Thank you

Plenty of posts about tires if you search. But to save you the trouble the tun flats suck and michelin super sports are the way to go.

well summer sports tend to last that long, my 3 series came with summer sports and they lasted about 25k so it all depends on who is driving the car and varies by brand, butsummer sports can last as little as 10k.

i'd just buy a patch kit , air compressor and normal tires. AMG cars (the c63 anyway) are like this and M cars. I have done this on my 3 series (don't have a w205 yet) and it hasnt harmed the TPMS or rims at all. honestly the ride is better and less noisy. not to mention 4 tires cost $600-900 now $1300 (i was going to have to replace some bridestone potenza s0001 runflats)

contiextremecontactt DWS they make in the 19" rim size. i've had them on a car before and they are a great tire, and they are all season ultra performance sport tires so they last 35k-40k miles. when i had them they felt better than that cars original summer sport tires (pzeros, but non runflat) on my particular car (audi a4 quattro). could be a good choice, roughly $200 a tire at 19" size. maybe pirellis just aren't that great

I 'm picking up a new c450 in 2 weeks and have similar concerns about the 18" run-flats that it will have. Not happy about the prospect of needing to replace them avery 8-10k Others have recommended the Michelin Super Sports as a replacement. I would not drive them without a spare, but a full size spare will take up too much trunk space. Does anyone know of a compact spare available which will work in an emergency.

The 18" all-season run flats are not the problem, it's the 19" Summer performance tires that wear more quickly.

I had both sets for my old 2015 C300 Sport 4Matic, and even after 6,200 miles, my 18" all-season run flats still looked like new...but the 19" performance tires did show some sign of wear after only 5,000 miles.

I am looking for 18" all-season non run-flat tire for my C450 because I would prefer not to have to change tires in the winter. The OEM run-flats are stiff and noisy so I would prefer a softer and quieter tire. What tires would you recommend?

S500Sport

I just got the C450, after reading this post I'm concerned about changing these pricey tires often. How has your experiences been? MASS, are your tires still faring well?

I picked up a E Class MB T135/80r17 compact spare and a MB jack on eBay for my C300 sport with 18" rims.

I only have 1,551 miles on my 19" silver multispoke AMG wheels/MOE Pirelli tires...which I bought as a brand new "take off" set from ebay. The fronts have some slight wear on the edges, but the rear tires are like new. I've read that driving with the 19" performance tires at 40 degrees F or lower REALLY makes them wear out quick (there's even a warning about this in the owners manual).

Since I have two sets of wheels/tires for my C450 (18" AMG wheel/all season tires that came with my car I'll use for Winter, and the 19" AMG wheel/performance tires I bought on ebay I'll use for the Summer...that and the year experience I gained from this similar setup I ran on my 2015 C300...I believe I'll get at least 2 years out of my 19" tires, and 3 to 4 years out of my 18" A/S tires...driving about 12,000 miles a year.

Here are pictures of the 19" MOE performance tires from my old 2015 C300 Sport 4Matic (that I still have, and selling the set) with about 5,000 miles on them...

My car came with Continental SSR Runflats (18 inch), not the Perelli's.

MASSC450

As did mine.

Both sets of 18" AMG wheels I've owned had Continental SSR MOE all-season runflats, and both sets of 19" AMG wheels had Pirelli P Zero MOE performance runflats.

S500Sport

Any difference between SSR and Perelli's? Also, how does the negative camber affect the tires?

Stupidnewbie

I've been very happy with my Continental DW non-RF tires. After 10,000 miles, they are wearing MUCH better than the RF's, they are much more comfortable of a ride, and they get better fuel economy (probably due to the difference in weight). They are non-directional but they are asymmetrical for water displacement. So, over the summer when rain wasn't an issue, I had the fronts rotated with the inner side out. I'd guess I have about 70% tread still, with the front wearing very even.

kleinebin

Good luck with that...

MASSC450

Can't really speak to that exactly...all I know is the 19" performance tires definitely out-handle the 18" all-season tires ...and wear faster than the 18" tires as well.

Did you end up changing your tires and how pilot Super Sports working out for you? Thank you

I don't get the whole run-flat thing. I called a tire shop to get an estimate on winter tires recently and they said that they wouldn't install anything but run-flats on the car because that is what comes from the manufacturer. That seems stupid to me. I mean, if I get a flat, I'm calling Mercedes Assistance and having the car towed; Am I way off base here?

Also, my car came with the Crapinentals. I'm now running Blizzaks on my 18s and come spring, I'm getting some proper rims and putting good performance tires on. I figure between swapping the two out each year, I can make them last though the lease (45k), then put the Conti's back on when I return the car. That way I get the most out of my money for tires and don't have to spend any on run-flats. I feel much better about that situation.

C450-nick

You can put pilot Super Sports on those rims to. I'm getting the ecu tunned and the tires a week after. Find a tire shop who has the tires have them do it. With OE tune 448hp and 533tq combined with the MPSS tires I'm hoping to transform the car. I can't really find any info on MPSS nobody have tired them on c450 I guess. I'll let u know how it goes. Thanks.

sean1.8t

Sure you could, but why would you want to? You'll end up spending $100 each time to swap the tires. That's $600 over just three years. I'd rather put that money towards aftermarkets that are wider (Read: Wider tires) with the proper offset to line up flush with the fenders.

Man I was trying to wait until I got bored of the stock power levels but OE is offering $300 off their tune right now...

C450-nick

I live in LA I just have to swap it once and keep the Continentals for the lease return PSS should last me 30k if no they have warranty. And yes OE will tune it for 955$ I'm getting it done next Wednesday.

I have purchased a set of volk g25 wheels with MPSS for my c450. The wheels weight 17 to 18 lbs each. Along with the reduction of weight in the tire, I shave 14 to 15 lbs per corner. This combination transformed the car into a much smoother riding machine. Every aspect has been improved. Mileage, braking, pickup, acceleration, road noise, etc. I am rotating the tires with Pirelli winter sotto zero 3. I figured I paid for high quality wheels, might as well enjoy them fully. I never curbed a wheel and worse thing, I'll get them repainted...

I strongly recommend MISS. They are the best option for the moment.

Mr. J

Michelin Pilot AS3+. I have the 19s on my c450 and they are great. Excellent handling in winter and on dry pavement. The Conti extremecontact ultra performance AS are also well regarded. The guy that runs the tire shop I frequent uses those on his wife's Audi.

MPSS have a decent tread life rating, but if you run them staggered cut that number in half (since they can't be rotated).
