I have a problem with the all-year tires Star Performer SPTS AS: For the first time these are extremely louder in the rolling noise compared to the previous Dunlop Winter Sport M3 (ok this is due to price acceptable), but I have in a certain speed range between 30 – 50 km/h with maximum effect at about 40 km/h a pounding noise which corresponds to exactly 1 wheel rotation. It is audible like an imbalance, but the steering wheel is absolutely quiet and I have the fitter in the balance. It is the same problem that someone with Goodyear Ultra Grip 7+ has: http://www.motor-talk.de/…/…rip-7-sehr-laut-droehnen-t2953421.html I would now change the tyre type and would need your advice, to choose from the following models. Mainly important would be the Performance on snow (yes, I know this is not perfect for all-year tyres): Kumho Solus KH21 Maxxis MA-AS Pirelli P 6 Four Seasons Glue QUADRAXER Vredestein QUATRAC 3 Toyo Vario-V2+ Goodyear EAGLE VECTOR EV-2 + Goodyear Vector 4 Seasons What is your recommendation?
