Gotta say, I’ve had some serious bad luck with my Merc E400 and its Bridgestone 245/35R20 run-flat boots.
It had new wheels and tires when I bought it with 14k miles on it last year. (Bought from a friend so I saw them installed by Wembley Tires).
Since then, I’ve done ~10k and have got through three tires, two of which blew on the inside rims, and one cracked wheel. I can’t believe I’ve gone through the better part of £2k in less than 18 months.
I’m based in London where you can seldom reach 30mph but where speed calming and potholes are ubiquitous. That said, I drive carefully, not aggressively, usually on the car’s eco setting for fuel economy.
The car itself is wonderful, but I’m beginning to worry about what it rolls on.
I know run-flats have poor reputations for durability and ride comfort, but I had them on my previous car for the seventeen years / 100k miles I owned it and hardly got through any more (Pirelli Zero 205/55) boots in all that time.
Bridgestone are a premium brand but are they really this fragile?
Seriously considering another brand or even saving a packet on non-runflats and slime….
