I have plain alnacs(not 4G) on my Skoda Rapid .They are supersilent this coupled with light steering I feel if there are tyres under the car or not. Plus they flatenout mild speed breakers & potholes so nicely. My grouse is ride comfort at speeds more than 100 km. If I keep overtaking other vehicles rapidly (serpentine style like a African Mamba), it gives a vomiting sensation to my daughter & wife, and handling at corners at good speeds gives little bit scary feel(need to slow down). Noisy at what speeds? How are they for hard cornering in ghats(60 to 80 kmph) & highway speeds? How are the sidewalls? Soft or hard? Same questions for you.
