I have been reading a number of posts regarding peoples experiences with tyres recently covering ride, noise levels, crabbing, wear and replacement options.
I have the 20 inch AMG wheels and Pirelli Scorpion run flat tyres which I feel ride hard and are particularly noisy on certain road surfaces.
I will say that after 17000kms that they are wearing very well so far considering what many people have been reporting what theirs needed to be replace at.
We don't drive it to any degree of sportiness or have the need for a snow suitable tread either and generally my wife drives this car and more around suburbia that long highway miles.
I have recently had a 2 year service where it would / should have had the tyre pressures check and reset but yesterday I thought I would see for myself what they were set at.
Rears were 44 and the fronts were 35 and reading the recommended pressures I was shocked at how high they are. This would be IMHO the reason for road noise and a harsh ride.
Just as a trial I have dropped them down to 30 front and back and of course its way more comfortable in the short around the town drive but was wondering what others have been running and if anyone else has run with considerably less pressures in the quest for comfort.
In my 40 years in the motor industry I have never before seen tyre pressures much different to 35.
I will make enquires with Pirelli and see what they consider to be a safe low pressure setting as well.
