Boat Trailer Wheels
Boat trailer wheels and tyres do a lot of work every time you put your boat in the water, and even more whenever you take it out. They not only support the weight of your boat but also have to do it in some of the harshest environments the country has to offer. From summer Sun to saltwater, your trailer wheels have to face everything without complaint and then come back for more.
You cannot use just any tyres on your boat trailer. Because the weight of your boat is almost entirely distributed on just two wheels, most boat trailers require tyres with much stiffer sidewalls than standard car tyres. You may also have to inflate them to higher pressures so that the air can handle the weight of your boat as well. You want to clean the tyres after every use, and also store them out of direct sunlight as that can damage the rubber. Take care of your tyres and they will take care of you.
Wheels and Water
Saltwater is nasty stuff; it's extremely corrosive and your wheels get submerged in it every time you launch your boat. It's very important to rinse the saltwater off your trailer after every trip, especially when it comes to your wheels. If you let saltwater sit in your trailer hubs they can rot from the inside out. Once your bearings are gone it's all over.
One of the most common materials for boat trailer wheels is galvanised steel. This steel is coated with zinc, providing a barrier against corrosion. Another, though more expensive option, for anti-corrosive metals is stainless steel. Aluminium is another good choice, but be careful as it does not have the same heavy-duty strength as steel.
Looking at Trailers
Always double-check a trailer before you buy it. Any trailer with rust or other corrosion on the springs and axles is likely to also be at risk for corrosion on the wheels. Checking first, and replacing corroded wheels with good ones is a sure way to make your next trip to the water that much more satisfying.
