This is an excellent point. Most car manufacturers install tires
which give the car the smoothest ride, and suggest underinflating
them. Perhaps that's the difference noted in the newer Volvo starting
the thread?
Currently running 44 PSI in the tires on the '00 Outback. It tows an
AS-H26E at 70 MPH, even with 135,000 miles on the shocks. As a rule
you don't need an SUV... Until there's a very rough road into your
landout field! I'll take fuel economy 100% of the time over the
convenience of that one retrieve.
Trailers should have tires with 50 PSI or greater inflation. You see
lots of trailers running mid 30s inflation.
Modification is always possible. The 80s vintage Jeep Cherokee had a
bad reputation for towing. Changed tires and shocks on my '87 and the
combo became very stable. Many cars which have too soft a ride or
don't trailer as well as you like can be worked on.

Any vehicle can be much improved for towing by changing to higher load-
range tires. You'd be surprised how much difference the stiffer
sidewalls make when it comes to controlling sway. It's not all about
suspension. Tires are a BIG part of the equation.
