My new 2017 E300 came with Goodyear Eagle Sport All season run flat tires and I was kind of surprised since none of the last 10 MBs I owned ever had Goodyear tires on them.
What does anyone think about such a tire on a MB?
Seems to be OK but can't find any review of tire against some of the other more popular brands.
TireRack doesn't list it in any of there reviews.

They are fine, as far as allseason tires are concerned. I preffer high performance summer.

I also have the Eagle Sport run-flats (245/40R19) on new E300, and think they are nosier or harsher sounding than my previous E class cars equipped with Pirelli, Continental or Michelin (none of which were run-flat). They are supposed to last up to 50K. We'll see.

The specifications for Goodyear Eagle LS2 looks to be an exact match for the Eagle Sport, and you can find info and reviews at Tire Rack or America's Tire (and probably others). Good luck

My 2015 BMW 535 xdrive has 19 inch Goodyear LS runflats. BMW has used them as OEM for a few years.

Only issue is that as a runflat, it has a very stiff sidewall and hitting a pothole will transfer the impact energy to create a bubble on the sidewall and bent rims. I have had 3 tires replaced and rims repaired 5 times.

My 2014 E350 sport had Continentals on AMG wheels they weren't run flats but I had to bubbles and 2 bent rims also. I just had to replace a tire on my new 2017 E300 car 5000 miles with run flats couldn't be plugged, hole to big.

I wouldn't be surprised if many of the bent rims that we hear about are a byproduct of safety improvements. Other manufacturers have introduced rims that fracture under severe impacts. Maybe MB has opted for a softer rim for the same purpose. However, there is little doubt that the biggest culprit is low profile tires, there is simply no way that a 30 profile tire can cushion the impact that a 50 does. On some of these modern designs the tire looks like a "lip" of electrical tape around a huge rim!

The sweet spot for me is a 45 profile tire on either 18" or 19" rims.

The tires suck,when they fall into a pothole it feels like 500lb just got dropped into the hole. The whole car starts to shake and vibrate. Has anyone switched the tires to none run flats? I am looking forward to switching/

I have had runflats on several cars, going back to 2005 with a C6 Corvette. Stiff sidewall transmits bumps but the newer generation of runflats with better engineered suspensions have reduced the harshness.

Runflats are about safety. Switching them out is a gamble; consider all the pros and cons before you do so.

Ive never had a blow out, but have heard alot of negative reviews about these tires and bubbles. Also what would you do if you get a flat while in the desert middle of nowhere on runflats?

Safety has little to do with it. Its primarily a cost reduction measure. There is also a minor component of weight reduction. I get rid of them immediately. I replace them with with a compressor and tire repair kit.

Not sure I would consider runflats as a cost reduction measure. The cost of the runflats run about 50% higher than the non runflats (e.g, Continentals) that were on my 2015 E350.

You can drive on a deflated runflat for a good 40-50 miles. Maybe more. I refer to them as a safety feature as it allows you to drive to a safe place and get the tire replaced. If you are driving from LA to Vegas along Death Valley, you can nurse the car as far as you can go and just call Roadside assistance.

Runflats don't help if there is sidewall damage. I never take a road trip without a spare tire, a repair kit and compressor. Around town I can leave that stuff behind to save on storage space, etc. That said, I've always replaced runflats with conventional tires as soon as possible.

The Mercedes "extended mobility" tires are limited (not up to runflat specs) if the vehicle is fully laden.

Though runflats may cost more retail, they cost only slightly more as oem. A runflat can drive "up to" 50 miles, a spare full spare can drive 20000 and a mini spare 100's. Its all about the beans and weight. Its also seen as a convenience factor since you don't have to change it. Furthermore, most people have become so detached from operating a vehicle they wouldn't even know how to change a tire! The E class has a nice big space in the trunk floor where I'll be placing an 18 inch spare I have in the garage for my C class.

2015 E350 photo after hitting a pothole and having to drive a short distance off a highway to a safe area. In 45 minutes, the donut was on the car and I was able to continue my trip into Manhattan.

On a runflat, I would have been able to Manhattan and then to my dealer to replace the tire under my wheel and tire protection plan.
