Can I use car tires on my boat trailer?

You want trailer tires on your trailer, not car tires. They have a stronger sidewall as previously mentioned, and are designed for trailering. Goodyear Marathon trailer tires are good ones. Some folks like Carlyles, others don't.

Can you put a regular car tire on a trailer?

Oh no! I'm sorry to hear about your flat tire. Your travel trailer requires specific tires, so you can't put your car's tires on a travel trailer. Regular car tires can't handle a travel trailer as they're Load Range B rated.

Are boat trailer tires different from car tires?

A tire made for a boat trailer is going to have "ST" on the sidewall, or the words "Trailer Use Only." Unlike tires on your car, trailer tires have strengthened sidewalls to handle the weight of a boat, especially when rounding corners. Trailer tires are either bias ply or radial.

Do you have to use trailer tires on a boat trailer?

Your Trailer Needs a Certain Type

Special Trailer (ST) tires are the only type you should use on your boat trailer unless you're willing to risk damage or potentially an accident. ST tires have robust sidewalls to handle lots of weight, which helps avoid tipping your boat onto the road while cornering turns.

Can I use truck tires on my trailer?

Expert Reply: Light truck tires (LT) are sometimes used in RV applications but generally not on utility trailers. Light truck tires are a type of passenger vehicle tire and as such they are not built with as thick of a sidewall as trailer tires. A thicker sidewall allows a trailer tire to handle more vertical load.

The Truth About Boat Trailer Tires (Boat Trailer Tires 101)

Can I put radial tires on a boat trailer?

For a boat trailer, or any other trailer used on pavement a radial tire is preferable. A radial tire will have a more flexible sidewall, which provides better tread contact with the pavement. Radial tires also do a better job of shedding heat.

Why can't you use car tires on a trailer?

If you run highway speeds or trailer heavy the car tires will fail. consistency of rubber and beefed up sidewalls (and probably more as well). For me and my safety, I'll only install tires designed for their specific use. I don't go the cheap route on safety items...

Do boat trailer tires need to be balanced?

Since the primary duty of a trailer tire is supporting a vertical load, rather than gripping an automobile through turns, trailer tires do not have to be dynamically balanced like passenger car tires do. Steering and cornering are less of a concern on a trailer tire than they are on an automotive tire.

What pressure should boat trailer tires be?

Boat-trailer tires require a lot of air pressure — in most cases, between 50 and 65 psi. In fact, the correct tire pressure for your boat trailer is almost always the maximum-rated pressure for that tire, which is molded right on the sidewall. Maintaining that trailer tire PSI is critically important to towing safety.

What is special about trailer tires?

Trailer tires differ in that they don't provide the power from or steer your car. They are also designed to dissipate heat because of the weight they carry, which can be much more than a standard passenger tire. The most common trailer tire type is known as special tire (ST).

What is the difference between D and R trailer tires?

The difference between the two trailer tire sizes is that the letter D in the first size you listed ST205/75D15 stands for bias ply and the letter R in the tire size that they put on your vehicle stands for radial.

What is the difference between LT tires and regular?

An LT tire is built more robustly than a P-Metric tire to handle heavy loads under adverse conditions. Heavier body plies and larger bead bundles allow LT tires to be inflated to higher pressures, thereby increasing the tire's load capacity. It is the air inside the tire that carries the load.

Should I inflate my trailer tires to max psi?

When it comes to trailer tires you always want to have them inflated to their max psi when cold. Not only do you get the full capacity at the max psi, you also will generate less heat in the tire since there won't be as much flex in the sidewall, you'll get better wear and better fuel mileage.

Why does my boat trailer bounce?

Any trailer hauled without its load will bounce. Boat trailers, for example, are made with stiff, solid axles with loose springs, which causes them to jump a lot when not weighed down. If your trailer still bounces while loaded, there could be other issues that need attention: Your tires aren't properly inflated.

What is the difference between car and trailer tires?

Car tires transfer power from the vehicle to the roadway and respond to sharp turns while maintaining traction and grip. Trailer tires carry heavy loads and have strengthened sidewalls to help with swaying during operation.

Why do my trailer tires keep blowing out?

A lot of trailer tire blowouts are a result of heat build up that causes the tire to fail. There are several things that can cause too much heat to build up but the main two most likely suspects are overloading the trailer and/or under inflated tires.

How often should you change boat trailer tires?

According to rubber industry research, trailer tires need to be replaced after 3–5 years of use, even though they usually appear to have plenty of tread left.

Are Bigger tires better for trailers?

Larger tires will typically have a higher weight rating. Tires with a higher weight rating will not increase the load carrying capacity of the trailer, so you will still be limited to the weight capacity of the axle.

How do you stop a trailer from bouncing?

You can try shifting some weight in the trailer forward to add some tongue weight and that would help eliminate some of the bounce you are experiencing. Also, make sure you are towing it as level as possible. You may need a different ball mount.

What does St mean on trailer tires?

Tires on boat trailers have to be ST tires which stands for Special Tire. ST tires are designed specifically for boat, car and utility trailers. They are built to carry heavy loads on non-powered axles and are rated for a maximum speed of 65mph.

How do I know if my trailer tire is bias or radial?

What is the difference between a radial and bias ply trailer tire?

1. A radial trailer tire is constructed with steel belts of the tire running at a 90 degree angle of the tread center line.
2. A bias ply trailer tire is constructed with nylon belts of the tire running at a 30-45 degree angle of the tread center line.

What is a better trailer tire bias or radial?

Radial tires, however, do perform better than bias tires, and that performance is quickly noticeable. The ride is smoother, the trailer does not bounce and sway as much, and radial tires have a longer life. The most important characteristic of any trailer tire is its ability to carry a heavy load.

Can you mix bias ply and radial tires on a trailer?

Bias-ply trailer tires

No matter which type of trailer tire you choose – radial or bias-ply – make sure you don't mix them on your trailer. Since their internal construction is so different, each type performs differently, and combining them can negatively affect your trailer's ride quality and the tires' life.

Does trailer tire size matter?

In general, smaller diameter wheel sizes carry smaller diameter tires — and carry less total load. On the other hand, they offer lower trailers and less vertical intrusion above (smaller wheel wells, fenders, etc.), albeit, they also give less ground clearance. In general, wider tires carry more load.
