I have a GLC 300 with Pirelli Scorpion Verdes run flats 235/60 R18 tires. They started cupping at 12000. At 20000 they are so loud I can hardly stand to be in the vehicle. I looking for suggestions on replacement tires?
I am on my 3rd set of tires after 30k on the car. Mercedes knows of this problem but will not do anything about it 10k per set of tires is a little insane. Mercedes won't do anything until someone brings legal action against them. I will soon be forwarding this complaint to the state attorney general to see if anything could be done about this. I'm sure if you raise a little kane with Mercedes you will get some action.
I've replaced mine with Michelin Pilot Sport 4S, best tire I had in a while as it's really comfortable, no noise after 10k and grip is amazing. It's non-runflat and some shuddering I had with stock tires is gone too.
