[Vintage-race] Trailer tires

[Steve Steers]

Years ago I blew caps off tires hauling a heavy car at speeds around 70.  It
was my first trailer and I was hauling a heavy 37 Lincoln Zephyr coupe to
Hershey.  The tires were old and checked, but had good tread.  I ended up
replacing them on the road.

I just changed my trailer tires after 7 years.  No blowouts.  They were D
Rated, had plenty of tread but on inspection, one had a bulge, and another
was cupping. The trailer is stored inside, so there was no sun/ozone damage.


My view is the combination of age, high loads and lower than max pressures
is what gets them.  Heat is the enemy.  Low pressure causes high flexing and
that generates enormous heat, creating a set up for failure.

When the tread came off of my trailer tyre it did not loose pressure.  I
discovered it when I had stopped for the night.
A pressure monitor would not have helped untill it blew out.
