[a/s] Truck "sway" - while SOLO!

[Jerry Flanders <jflanders2@xxxxxxxx>]

Add this to the 'Knowledge Database" on trailer towing stability:

I recently got a set of 4 new tires and retired the OEM ones that came with
the truck when it was new (got 66,000 miles out of them!).

Took a trip with the truck this past weekend - about 500 miles RT. I was
surprised to find that passing 18-wheelers blow me around now, with just
the truck solo - this has _never_ happened before! I also notice a very
slight "wandering" effect when driving straight down the road.

I remember this once happened to me with a conventional sedan and new set
of tires. Problem then was cured with a couple more pounds of air pressure.

I will find the appropriate air pressure for these new tires also, and
expect the problem to disappear then. I mention it now to point out that
there are a LOT of factors that influence driving stability, whether towing
or not.
