Hello, I bought a Mercedes S-Class V222, year 2016 with 105tkm. Then there were 18 inch summer tyres, but they were already pretty bad (10 years old and loud). But the car drove clean and quiet with it. I bought and had used 20 inch Mercedes rims and new Hankook winter tires. Unfortunately, the car now runs far too restless. Hankook had already been on a CLS C218 as a summer tire and was actually satisfied with it. Aschine showed 0 everywhere. However, it works “only” in 5g steps. Max. are I believe on one wheel 70g weights on it, the others have less. I would have to look again exactly, but actually this should still be in frame. I could now just balance out somewhere else and if necessary let go. However, I have the feeling that the tires simply run round. I feel already from 60km/h that the car drives restlessly. Moreover, the rolling noise gets louder and louder and it sounds like you’re constantly driving over something. Do you want to complain to the dealer or the manufacturer? I want to have this checked myself anyway. Because I can be, I send the tires back and dealers/manufacturers say everything ok without being able to prove it. But what do you need to be able to check a tire? Finding a dealer with Hunter machine would also be a possibility, but I don’t actually see that in new tires. Rims must of course also check for concentricity in order to be able to exclude this. I am grateful for every advice!
