I just replaced all the lights and wiring on
my trailer, but I still have a problem with
the lights blinking off and on while driving.
Sometimes they work fine, and I’m not
sure what is causing it. G. Wills
you have a tilt trailer, make sure there’s a
jumper wire between the trailer tongue and
the trailer frame. Many tilt trailers will lose
their ground at this point, thus the need
for the jumper wire. After you’ve checked
the ground, test it without the trailer down
on the ball. If it works, then you know that
you’re not relying on the ball for a ground.
Check all other connections as well, and, if
you want, grease your connection to help
prevent corrosion. If you can’t get the trailer
lights to work without the ball being hooked
up, then put a pair of jumper cables
between the truck and the trailer to make
the ground. If this works, go back to the
truck wiring and make sure it’s feeding
the trailer a good ground.
DUSTIN HOOVER: Every trailer has a
white ground wire that must be directly
bolted to the trailer from the tongue
plug. Make sure this wire is good. If

What’s the difference if you replace trailer
tires with passenger car tires with the
same load rating? My friends and I are fed
up with the sidewalls of trailer tires dry-rotting after two or three years, even when
stored inside. Larry Earthall

TED SENSENBRENNER: There’s a big
difference. The sidewalls on trailer tires are
stiffer to prevent swaying. It’s dangerous to
put light-truck or car tires on a trailer. For
a trailer, use only ST-rated tires (“Special,
Trailer”). If you get into an accident while
towing your trailer, using the wrong tire,
your insurance company may deny your
claim. We all wish that trailer tires lasted
longer. One way to extend life is to remove
the wheels during long periods of storage.
