What air presure do you run on your trailer tires?

enough to keep them looking right. Don't laugh, the tires should have enough air to keep the the sidewalls true all the way around without overinflating causing the tread to expand in the center or underinflating causing the sidewalls to squish out at the bottom. Its dependant on the boat/trailer weight. If the amount of air psi to keep the sidewalls true all the way around exceeds the max recommended pressure marked on the tire then a higher weight rated tire is needed.

My Extreem trailer owners book says 50 psi. Any less will heat up the tires and they will fail.
I check them at 50 psi before every time the boat and trailer are pulled.
50#'s
You should keep them at the rating on the tire. The readings should be done at cold temperatures. If run the less the tires will run hotter!
run them at the cold specs but check them after a long tow, or during. You really don't want them to exceed the max recommended pressure. You also want to make sure they are of the proper load range to carry the weight of your boat.
Whatever the tire says....especially on trailers. If you have Carlilles (sp) junk them. Their only rated for 55mph...and as we all know, nobody drives 55. I run radial BFG's on my trailer and truck.
Radial car tires on a trailer are a bad idea, Not enough sidewall strength. Trailer tires are designed to be somewhat of a 'suspension' as most trailers really don't have one. I suppose you can get away with it if your setup is light enough, or you're running triples, but I always run trailer tires. I also run them at the Max recommended PSI.
I set mine at the max pressure, and have yet to have a failure. Even with Carlisles on my last trailer and many trips across the desert.
They seem to run about as hot as the car tires. I have a laser temp sensor. High 90's when the weather is normal, but I have had them read up to 120 or so in the summer. They will all usually read within 5 degrees of each other.
