Did anybody replace runflats by standard or performance tires on the MCS?
Does it make a big diiference in handling and comfort?
What does happen in case of a flat or blow out with non run flat tires?
Does the road assistance service covers towing the car in case of puncture or whatever without runflat tires?

 

Replaced with Yokohama AVES 100s from tirerack.com
Improved handling(once tires warm), slight ride improvement
and I also went to a 16lb wheel so car is definitely quicker
with the weight loss.
