Hello all, I bought a used BMW 4 Series GC in March. It was tired all around with Winter Sport 4D ROF, the rear tires the dealer replaced with M3, because in the middle of the car the 4D on the front axle is 2 years old, has 28Tkm down, unfortunately a sawtooth, is hardened because it was previously moved with winter tires also in summer. The noises coming from the sawtooth are increasing. Profile is still good 5-6mm. The consideration for the front axle would be two I have now considered the following tyres: -DUNLOP WISPM3 225/50 R17 94 H – F, E, 1, 67dB -RUN-ON-FLAT *-EXHIBITION M+S -HANKOOK W310 225/50 R17 94 V – F, C, 2, 72dB HRS RUN FLAT M+S -PIRELLI W210S2 225/50 R17 94 H* – E, C, 2, 72dB ? Specific saw tooth inclination? On the Dunlop website it is described as “high performance with comfortable tuning”, but otherwise hardly anything can be found. Hankook and Pirelli have an asymmetrical profile, are a bit cheaper than Dunlop, but should be louder. Advantage M3 would be the same profile VA/HA What do you think about it?
