Good evening dear Phaeton colleagues, for a few weeks I have had a V6 TDI from 2007, with Pirelli 255ers and about 6mm profile on 19 inch Omayt rims. After a few weeks of acclimatization I noticed a minimal but noticeable restlessness in the steering. He follows track grooves, “switches” in unevenness such as Gulli lids and generally in bad roadway etc. However, with a flat track and good surface the steering is quiet and the driving feeling as it should be, so precise and gliding. The steering has not and also no poltern oä., which would mean on failed joints. Now I have for three days new Nokian winter tires 235 /55 R 17V on 8.5 x 17 Ronal rims drawn. The wheel grooves and the offset have completely disappeared, even on rather bad roadways. The steering is easy, precise and the driving feeling overall subjectively far more comfortable than with the 19 customs. I know this track groove effect of various Porsche and Mercedes SL models, however, is only to look at the high precision wheels of course not something like the same as regards to the wheel length.
