What tire pressure do you folks run in your trailer tires? I have mine at 40# and they seem a little "soft" with the boat on there. Any advice before I head out on a LONG roadtrip?

I run mine right at the max recommended cold inflation pressure which is cast into the sidewall. Don't exceed this pressure, even if the tire looks 'soft'. Exceeding inflation pressures is a recipe for disaster.

Many C25 trailers are 'under-tired'... a lot of people try to save a few dollars by putting passenger car tires on them rather than 'proper' trailer-service tires. Look at the 'maximum load' rating on each tire and add them up. If they don't come up to 7,000lbs (or so) you're probably overloaded.

Another thing to check is that the trailer frame is level with the pavement when loaded. (controlled by the height of the trailer hitch). If it's not level you can end up with extra load on one axle and too little on another.

My trailer rated tires call for 70 psi (as is posted on the sidewall). A truck stop will have a guage that reads that high. Don't forget to give your wheel bearings new grease as conditions require. Fair winds. Todd Frye

70 pounds - yikes!

Guess it depends on the tire design and/or bias verses radial. My bias plys are stamped 50 pounds . . . sounds like you need to go by the manufacturer's spec Nate.

I keep a tire iron handy and check the lugs every rest stop. Do you have the spring loaded grease caps? Do you have a spare tire - mounted? A jack that will fit under the trailer axle? A spare wheel bearing (or two)?

Checked the sidewalls when I was at the boat today...seems I might have them a little low. The rated pressure is 50#..so I will top them off in the AM. Yes, I have a jack/spare/extra bearings/lug bolts/bearing grease/bulbs for the trailer and rosary beads for good luck (I'm not even Catholic but what the heck!) Thanks guys!

I had planned to put my boat in this wek and took it out of storage last week. Apparently had a shot wheel bearing on my EZ loader. Got the thing to the club yard, but the right rear wheel seized when I tried to move the trailer a second time. It was Hot, hot hot. Luckily, a friend who I had helped launch his boat had a heavy duty hydraulic jack which we placed under the trailer frame to pull the wheel to take to local marina where they replaced the wheel bearings. The inner bearing was shot. Now that the boat is in the water, am servicing all four wheels. That hydraulic jack, which is rated for 6000 lbs, was a godsend. I now have one.

Speaking of bearings...A long time ago, a friend and I were on the highway when we started hearing funny noises coming from the rear of his Mustang. As I looked into the rear view mirror outside the passenger window, I noticed that the rear tire looked kind of strange...It was sticking out about 3 or 4 inches more than it should!

The bearing blew out and the axle started pulling out of the axle. We pulled over immediately and just as we got out of the car and to the offending wheel, the wheel burst into flames!

After kicking and throwing snow on the tire to dowse the flames, we let out a sigh of relief because the whole wheel could have took off at highway speeds.

Oh, about the jack...I keep a hydraulic jack in my truck at all times.

I read your post and just sat there thanking my lcuky stars. Thanks for putting it on. If I had had to pull that thing any further, it might have done the same thing. I am SO lucky!

You might be very lucky.. I saw one burned-out powerboat sitting alongside the interstate a number of years back. The wheel bearing went, tires blew out and caught on fire, the fiberglass hull got started... and that was all she wrote till the fire dept arrived.

There's the famous chronicle of the ill-fated Mac 25 trailer-sailing to Florida... where the hapless boater had his smoking trailer tire pass him by on the highway. On the same trip, he discovered that Florida launch ramps are slippery and that a chevy surburban doesn't float.
