We just bought a 2001 Lund Mr. Pike a couple weeks

had to take the boat with us. About 40 miles from
home, the driver's side trailer tire blew out while on
the freeway going almost 70mph. Then, about 100
miles later, the OTHER trailer tire blew out - this
time we were only going 60mph, as we were
paranoid after the first blow-out.

There is another point here. Yes, the tires could be underinflated.
Yes they could be undersized for the weight of the boat and trailer (I
get about 1115 pounds for the boat). Yes, you could have picked up
nails in both tires, short enough to not (yet) affect the tires on the
towing vehicle, but long enough to lose tire pressure on the trailer
and blowout.

When you say "had to take the boat with you", did you stuff it full of
"bringalongs" like a U-haul? There are weight limits on tires...
