What to Look for in a Boat Trailer Tire – a Buying Guide

Boat trailer tires are often neglected and are not checked on a regular basis compared with tires found on your car.

This is really worrying because unlike standard automotive tires, boat trailer tires will be subject to far tougher conditions that include constant exposure to UV rays, moisture and much more.

This will also affect the rim itself because it has not yet been galvanized, it may corrode, which causes tires to deflate over time.

Other notable parts of the trailer that should be maintained accordingly are the boat trailer hubs.

These should be regularly checked along with your boat trailer tires to avoid being left on the side of the road.

We are speaking from experience because after picking up a recent boat and trailer combination, the wheel actually fell off the trailer, which is shown in the image below.

To help you make an informed buying decision with regards to boat trailer tires, we have produced the below-buying guide.

Load Range & Weight Ratings

You will notice that every trailer tire will have a load range marked on the sidewall with A being the lightest to E being the heaviest rating.

The measurement is used to determine the maximum weight capacity that each tire can carry with many boat trailers being between B and C.

Many boats do not weigh that much and requiring a heavyweight 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 manufacturer’s recommendation in terms of weight capacities.

Boat 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 traveling.

Running a flat trailer tire is 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 sidewall of the tires, where the common rating is 66 MPH but many exceed to 66 to 75 MPH.

Wear and Tear

Many trailer tires are built to last many years but you should perform visual checks on a regular basis.

You will want to firstly check for the most common issues, which are 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, so the wear and tear may be minor.

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.

Trailer Usage

You should always ensure the tire you put onto your boat trailer is labeled with ST, which signals it is designed for a trailer.

All of the best boat trailer tires above have the ST marking on the sidewalls and are safe to use.

If you are also buying a rim to fit the tire too, you may want to check that it has been galvanized.

The rim of a wheel that is not galvanized will become heavily corroded over time and can cause the tire to lose pressure.

However, if the rim is not galvanized, you can simply do it yourself at a relatively cheap cost.

Tire Size

When it comes to choosing a tire size for your boat trailer tires, you will want to try to keep to OEM recommendations.

However, you may install a new rim that is a different size, which may mean you have to reduce or increase the profile of the tire so that it fits.


Boat trailer tires are relatively cheap and can be long-lasting but so many people decide to take the risk on damaged tires.

All of our recommendations are all suited to the tough marine environment and are suited to a range of applications.

If you notice any damage to your tires or wheels of your boat trailer, get them changed before hitting the road.
