Alpina D4

Post by Rossandrew » Wed May 08, 2019 11:07 pm

I’m after some advise regarding tyre wear and road noise on my D4 #148.
The front tyres have done 20k (PS2’s) and have about 2-3mm of tread.
I’ve started to notice a different road noise, a kind of humming which increases with speed, no knocking or clunking when turning so I’m wondering if it is a characteristic of the PS2’s when they get low on tread.
I replaced the rear tyres about 5k ago with PS2’s, should I replace the fronts with the same or are the newer PS4’s comparable/compatible.
Many thanks.
