Several months ago I had the front end on my '74 standard aligned at a
VW shop which has been in business for something like 30 years.
Driving the bug afterwards I felt that the front end stability was a
bit off, but put that down to the alignment. After several days of
this I finally got around to checking the tire pressure (165s, radials)
where I was suprised to find that all the tires were now at 32 psi.
Made me wonder is someone goofed, or the higher pressure is some new
recommendation. But I still adjusted the pressure back to values which
are closer to the recommended ones.
