Trailer tires and wheels

Problems with tires and wheel bearings can leave you stranded on the side of the road and can even become a safety hazard.

Check tire pressure

Since tire failure due to low air pressure is probably the number one cause of trailer failure, it is a good practice to check trailer tire pressure before getting on the highway.Inflate to the maximum rating listed on the capacity label on the tire or trailer, which may be 60psi or more.Under low pressure, heat can build up in the tires, causing them to fall off and fail, a dangerous situation at 70 miles per hour.Tires naturally lose a pound or two of air pressure per month, so it’s especially important to remember to check tires after the trailer has been idle all winter.Don’t forget the spareNot all tugboats have a spare tire.If you don’t have one, buy one and a mount.Good insurance.Remember to keep air pressure on spare parts and make sure you travel with tools and jacks that you can use to change a tire.

Tyre wear

Check trailer tires regularly for wear and age.Most boats don’t wear the tread of trailer tires, but if you notice uneven wear on a tire, it could be a bent shaft, or an alignment of shafts.This should be fixed before the tire goes out.The National Transportation Safety Board says tires that are more than six years old should be replaced.The last four digits of the Department of Transportation code on the side wall of the tire indicate the month and year the tire was manufactured;”3517″ indicates that the tire was manufactured in the 35th week of 2017.The tyres below the trailer should all be ST(Special Trailer) type tyres, which are specially designed for trailers and have stronger ropes and harder sidewalls than LT(light truck) tyres.Check wheel bearing

Wheel bearing

Failed wheel bearings are another common cause of trailer failure.Bearings may rust if they are contaminated with water, which is why most boat trailers are equipped with wheel bearing protection (bearing partner is a popular brand and has become a common term for all bearing protection).Wheel bearing protectors use spring-loaded pistons to keep grease from the hub under light pressure and prevent water from entering the hub and bearing assembly.There will be a grease device in the center of the protector to increase the grease and maintain the pressure.Read the instructions with your trailer to add grease details.Even with bearing protection, it is a good idea to check and repackage wheel bearings with fresh grease every three to five seasons.
