hello since yesterday owner of a vw phaeton v6 3.0 tdi 4motion and since today member in forum. I need, according to the season, winter bikes for the phaeton. there are all kinds of variants offered; but mostly not the ones from my vehicle license, which read: 235/50R18 101Y can I use this indication also mature with the gr. 235/60 R 16 100? these come from the phaeton V 6 3.2 petroler (so no 4motion). best thanks for this first aid…
