If you are towing with an automatic transmission, you should never tow in overdrive. Trailer Know your trailer. Do not overload. Follow the axle manufacturer's recommendations for checking lug nuts on wheels. If the trailer has been idle for several months, it is a good idea to grease the bearings as condensation can build up in the bearings.
Regular use keeps the bearings free of moisture.
Check tire pressure on trailer regularly and keep inflated per the PSI listed on the sidewall of the tire. Make sure the hitch weight is between 10 and 15 percent of the trailers loaded weight. Check your coupler periodically for adequate lubrication. A dry coupler and hitch ball will cause excessive wear. This will result in coupler or component replacement.
