If the door seal shrinks and the door closes not that easy anymore as the edges come out, the wind noise at high speed becomes louder, here is what my friend "TAKE" in Japan made:

I did the same, just using some runner and roll ot as shown here. Cut the old seal at the bottom.
In my case on all doors the sealing shrank by 30-40 mm over the years.
