Boat Trailer Tire and Rim Buying Guide

boat trailer hub failure

Its vital that you ensure the trailers hubs, wheels and tires are all healthy before setting off because danger could not be far away. Below are some factors you should consider before purchasing your tire and wheel combination for your boat trailer.

Load Range & Weight Ratings

You will notice that every tire will have a load range marked on the sidewall, with A being the lightest to E being the heaviest. The measurement is used to determine the maximum capacity that each tire can carry with many boat trailers being between B and C.

Many boats do not weight that much and requiring a heavy weight rating for tire can be pointless at times. However, if your boat exceeds the load range/weight rating of the tires, you are landing yourself into a world of trouble. It is highly advised to go with the manufacturers recommendation in terms of weight capacities.

Tire Inflation

So many people forget to check the air pressure of tires on their cars let alone on the trailers of boats. Unlike the car tires, boat trailer tires require much higher PSI and need to be checked regularly as they do heat up.

You should always inflate the tire when cold as the PSI will increase as the tire becomes heated whilst travelling. Running a flat trailer tire is a cause for disaster and will more than likely cause a blow out at high speeds when you least expect it.

For those that travel at a faster speed than most other driving towing, you should be putting in a higher PSI. Speed rating will be displayed on the side wall of the tires, where the common rating is 66 MPH but many exceed to 66 to 75 MPH.

Time to Change Tires

Many trailer tires are built to last but deciding when to buy new tires can be achieved quickly. You will want to firstly check for the most common issues, which is cracking on the sidewall, inability to hold tire pressure and general tire wear.

It is always important to check the age of the tire as some trailer may not get that much use. Simply check the sidewall for the DOT time stamp, which all tires will have. If it is too old, it is advised to change immediately before any long journeys.

When you change the tires, always ensure that you get the rim checked out and balanced at a tire shop. A word of warning for those that go to “backstreet” garages. Always ensure the tire you put onto your boat trailer is labeled with ST, which signals it is designed for a trailer. If you check this after, return to the tire shop and ask for a refund. All of the best trailer tires for boats above have the ST standard on the sidewalls.
