Don't know about the 2.8, but the set I acquired and had serviced for my 3.1 were tested at 40 lbs. They were all final adjusted to 42. Not sure if that was a per hour pressure or just their tested pressure.

40 would be the pressure, not the lb rating.


They are both in the range of 15lbs. You can put 3.1's in a 2.8 and not have any problems at all. 2.8's into a 3.1 you MIGHT run a bit lean.

I thought 40 sounded a bit high.
