Tires do get hot normally. I think you would need a thermometer to
really know if you have a problem or not. Hot is sort of subjective.

I have an 18' Tri-Hull sitting on a single axle trailer. After driving
about 30 miles today, I noticed that both tires were quite hot. The
hubs
and rims were cool, though. Tires have proper pressure, and bearings
were
recently packed with high-temp grease. Am I missing something, or is
this
normal?





Tires aren't that old, but they are bias-ply Carlisles.


About 15 years ago, drove my disabled vet brother and his bass boat from N.
Ill. to Arizona to spend the winter with me. He bought two brand new bias
ply tires from Sears for his boat trailer. Best bias ply they carried. We
drove mostly 60 mph, max 70 mph. About 70 miles East of Albuquerque, the
side walls literally melted on the first, put spare on and one mile down the
road the second tire went. State Police found a guy in Albuquerque who
would drive out and lend us two tires to get into Albuquerque. Sears gave a
credit for the purchase price of the tires and told us that we should have
been sold radial tires instead of the bias ply as the flexing of the side
walls would cause the bias ply to fail whereas the radials handled the
flexing much better. No more problems with the radials. When I moved back
from Arizona, I went to Discount Tire to purchase two new tires for my 6.5'
x 12' cargo trailer. I asked for radials and they told me that I should go
with bias ply tires especially designed for big trailers as the flex of the
radials would cause the trailer to wander on the road. I currently had
radials and , yes, the trailer did wander a lot. Bought the bias, made the
trip and it was like the trailer wasn't even behind the truck. Still using
the bias tires that I bought, 4 yrs. later. So I guess the answer is to buy
a tire that is specifically designed for trailers, whether it be radial or
bias.
