I was a bit sceptical when I discovered MOE was Mercedes run flat system, I expected the car be harsh over bumps and skip on bumpy corners like my previous experience with BMW E90 Bridgestone run flats but was pleasantly surprised.
On the French motorways to the south of France, I found the car very stable and easy to place at speed (up to 80 mph officer). I have on occasions pushed the tyres and found them predictable wet and dry but never tried them on snow.
After driving 40000 mainly relax miles (it’s not a sports car) on the tyres I replaced the whole set with the same. Bit more expensive but the tyre are well matched to the car, even tyre wear and no tramlining even when worn to 2.0 mm, consistent behaviour over the life of the tyre. No experience a puncture on these tyres, so cannot comment on flat running. The tyre rim saver does not prevent damage, even with the lightest accidental touch of the kerb.
