What is Trailer Wheels

 

 

Your trailer's wheels are the only point of contact your trailer has with the road surface, making them one of the most important trailer parts. Having the right trailer tyres can make a huge difference in how your trailer handles, no matter whether it's a camper, boat, utility or fifth-wheel trailer.

Key Factors to Consider When Selecting Trailer Wheels and Tire Packages

 

Load Rating
An essential factor is to ensure your wheels and tires have a proper load rating and weight-bearing capabilities to handle your trailer’s loaded weight. Tire failure and wheel damage are often caused by overloading and underinflation of the tires. Compare the GVWR on your vehicle's trailer to the maximum load rating for the wheel and tire package. Select a load rating which is to meets or, ideally, exceeds your trailer's weight requirements with an ample safety margin. .

 

Tire Construction
Trailer tires come in variousconstructions, including bias ply and radial. Radial trailer tires typically have stiffer sidewalls and run cooler than bias-ply tires. This makes them well-suited for heavier loads and higher speeds. Bias ply tires have flexible sidewalls that provide a smoother ride quality. But they tend to heat up faster at highway speeds. Consider how you will use your trailer to choose the proper tire construction.

 

Rim Type
Trailer wheels come in steel and aluminum varieties. Aluminum wheels are lighter weight, more corrosion resistant, and have better heat dissipation. But they are typically more expensive than steel wheels. The lighter weight allows for more payload capacity. At the same time, steel wheels are more economical but heavier. Make sure your wheel’s weight capacity matches or exceeds your GAWR (Gross Axle Weight Rating) and hub size to avoid cracked rim repair or replacement costs.

 

Tire Ply Rating
A tire's ply rating indicates the number of fabric or steel plies or layers under the tread. Radial tires have a ‘ply rating’. This is based on the time when tires had actual cotton plys criss crossing from one bead to the other. Today’s radials use polyester, nylon, steel, and kevlar which are much stronger. A tire with a 10-ply rating may only have 4 or 5 actual plys but is equivilant to 10-ply in the old cotton ply system. Higher ply rated tires add strength and durability for heavy loads. Standard ply ratings for trailer tires include 6-ply, 8-ply, and 10-ply constructions. A higher ply rating, such as 14 to 18-ply, all steel construction is recommended for heavy-duty trailers with repeatedly large loads. This will reduce the risk of blowouts and punctures.

 

Tire Size
Select a tire size designed to fit your trailer's axles and fender wells. Trailer tires are commonly found in ST, LT, and TBR ranges based on intended usage. The tire size marked on the sidewall will also indicate the wheel diameter and tire width. Make sure to choose a size supported by your trailer's rim width and wheel openings.

 

Tread Design
The tire tread pattern impacts wet traction, hydroplaning resistance, noise, and wear. Trailer tires feature tread designs optimized for hauling applications. Look for a highway or rib tread pattern that provides plenty of tread surface and lower rolling resistance. . Make sure any specialty trailer tires match the load range and size needed.

 

Speed Rating
The speed rating indicates the maximum speed a tire is designed to safely travel at when properly inflated and loaded. Most trailer tires have speed ratings ranging from 62 mph to 75 mph. At the same time, light-duty trailer tires may be rated up to 87 mph. Choose a speed rating that matches your normal towing speeds for optimal control and handling.

 

Matching Sets
For best performance, traction, and tread wear, it's ideal to choose a matching wheel and tire package with tires sized and rated the same on each axle. Mixing tire brands, sizes, tread patterns, and levels of wear between the left and right side can impact handling, braking, and stability.

 

Spare Tire
Having a spare tire compatible with your wheel size and load range is essential in case a blowout or flat occurs. Ensure your spare has the same load rating, construction, and size as your trailer's tires for safe temporary use. A full-size matching spare is recommended for trailers.

Positive Offset vs. Negative Offset: Making the Right Choice
 
 

Positive Offset: Maximizing Space on the Drum Side

Positive offset wheels have their mounting pads adjusted away from the drum or brake side of the wheel's center line. This configuration provides more space between the wheel and the drum, making it ideal for trailers with larger drum components. Positive offset wheels are often used in heavy-duty applications where there is a need for ample clearance between the wheel and braking system.

 
 
 

Zero Offset: Perfect Alignment

Zero offset wheels have their mounting pads in line with the wheel's center line. This configuration ensures that the wheel is perfectly centered and aligned with the trailer's hub. Zero offset wheels are commonly used in standard applications where maintaining a balanced and symmetrical alignment is crucial.

 
 
 

Negative Offset: Maximizing Space on the Street Side

Negative offset wheels have their mounting pads adjusted away from the street or wheel side of the wheel's center line. This configuration creates more space between the wheel and the outer edge of the tire. Negative offset wheels are often chosen for trailers with larger tires or in situations where additional clearance on the street side is required.

 
Trailer Wheels
 

Rim: The rim serves as the seat for the tyre.


Wheel Disc: The wheel disc connects the rim with the hub.


Wheel: The wheel is the entire assembly, consisting of the rim and disc.


Rim width: The width inside the wheel flanges and is normally expressed in inches e.g. 4.50.


Rim diameter: The diameter of the wheel just inside the rim, where the inner edge of the tyre bead sits and normally expressed in inches e.g. 13"


Offset: The distance between the seating surface of the wheel/hub and the vertical centre line of the wheel/tyre unit. This can be positive offset, as shown above, where the vertical centre line is behind the seating point, when the wheel is fitted to the hub. Negative offset is the opposite and is sometimes known as inset.


Centre disc: There are also centre disc wheels that have neither positive nor negative offset; i.e. The vertical centre line is in exactly the same plane as the seating point.


Centre bore: The hole in the centre of the wheel disc, designed to accommodate the bearing boss and grease or dust cap. Size expressed in millimetres.

Stud or bolt holes: The holes by which either the studs or bolts fasten the wheel to the hub. Normally 4 or 5 in number, the size is determined by the size of the stud or bolt, either metric or imperial. The usual way of expressing the configuration incorporates both these factors, e.g.~
4 x M12 = 4 off 12mm studs or bolts.
5 x M14 = 5 off 14mm studs or bolts.
4 x ½" = 4 off ½" studs.


Pitch circle diameter (P.C.D.): The diameter of the circle around which the studs are arranged. Measurement given in metric or imperial e.g. 100mm, 112mm, 5.5", 4". The measurement of a 4 stud fixing is simply the distance between the centres of two opposite stud holes. A five stud fixing is calculated by taking the measurement from the centre of a stud hole to the edge of the centre bore x 2 + the diameter of the centre bore.


Studding patterns: The correct way to express a studding pattern, either of a wheel or of a hub is an amalgam of 9) and 10),
E.g. 4 x M12 on 100mm
4 x 1/2" on 5.5" (or 139.7mm)
5 x M12 on 112mm


Two piece wheels: Although rarely used as original equipment in today's light trailer market, a number of older trailers may be fitted with two piece wheels, particularly those using 600 x 9 tyres. It is vitally important that the nuts holding the two sections together are NOT loosened whilst the tyre is still inflated.

 
Can tires and rims designed for trailers be used for cars and trucks
 
01/

Load Capacity

Trailer tires and rims are typically designed to support lower maximum loads compared to passenger vehicle tires. Using trailer tires on a car or truck could lead to overloading and potential tire failure.

02/

Speed Rating

Trailer tires often have lower speed ratings than those required for safe highway driving in cars and trucks. Higher speed driving on trailer tires could cause them to overheat and potentially burst.

03/

Tread Design

The tread patterns on trailer tires are optimized for the unique handling characteristics and load distributions of trailers. This may not provide the same level of traction, handling, and braking performance on a passenger vehicle.

04/

Rim Size

Trailer rims are often narrower than those used on cars and light trucks. Mounting wider tires on narrower rims can lead to stability and safety issues.

Trailer Wheels and Tires Technical Definitions Guide

 

The wheel centerline is the exact center of the wheel, measured from front to back. The trailer tire needs to be balanced around the centerline for proper operation.
The wheel diameter is the distance across the trailer wheel at its longest, measured at the spots where the tire seals with the wheel.
The bolt diameter is the distance across the bolt hole where you will secure the wheel to the trailer.
The mounting pad is the part of the wheel in the center that touches the face of the hub on your trailer.
The drum side is the side of the wheel that faces your trailer and drum.
The street side is the side of the trailer wheel that faces the street.
The backspace is the distance between the mounting pad and the edge of the trailer wheel on the drum side.
The wheel offset is the space between the centerline of your trailer wheel and the mounting pad.
Zero offset is when the mounting pad is exactly at the wheel centerline (this is the most common offset with Trailer Wheels).
Positive offset is when the mounting pad is closer to the street side than the drum side.
Negative offset is when the mounting pad is closer to the drum side than the street side.

How Do I Know What Trailer Wheel Size To Get

 

 

Trailers do not operate in the same way a car does, and they do not come with a log book that sets out the correct size to get. Your trailer may be able to fit all wheel sizes. Fitting wheels and tyres that are too large or too small for your trailer can lead to damage or even serious damage.

FAQ

Q: How to choose trailer wheels?

A: For best performance, traction, and tread wear, it's ideal to choose a matching wheel and tire package with tires sized and rated the same on each axle. Mixing tire brands, sizes, tread patterns, and levels of wear between the left and right side can impact handling, braking, and stability.

Q: How does a trailer wheel work?

A: Wheel hub assemblies are a combination of parts that connect to the trailer tire. The purpose of the wheel hub is to serve as the glue between the tire and the axle. Tires are attached with studs to the hub assembly. The hub assembly then fits on the axle, which connects the tire component to the rest of the car.

Q: How many wheels are on a trailer?

A: The cargo trailer usually has tandem axles at the rear, each of which has dual wheels, or eight tires on the trailer, four per axle.

Q: What size trailer wheels do I need?

A: The most common wheel sizes for trailer tires are going to be 15 and 16 inches. For this size wheel, the most common tire sizes include: ST205/75R15, ST225/75R15, ST235/80R16 and ST235/85R16. These sizes increase in both diameter and width and as they get larger the ply rating of the tire also increases.

Q: How are trailer wheels measured?

A: Measure a five lug wheel from the edge of one bolt hole, skip one bolt hole and then the center of the next hole. In this case the ruler is not across the center of the wheel and you measure from the edge of one to the center of the other.

Q: What are trailer wheels made of?

A: Constructed from the highest grades of steel and aluminum, our heavy-duty wheels are able to take on more carrying capacity, while performing at the highest standards.

Q: Why do trailers have many wheels?

A: Load carrying heavy vehicles are provided with large number of wheels so that the load (weight, force) is distributed over larger surface area of the wheels in contact with the road. Hence, the pressure decreases and the tyres dont get stuck in the ground.

Q: Are all trailer wheels the same size?

A: Of course, trailers are a different vehicle altogether and do not perform in the same way a car does, plus they don't come with a logbook that stipulates the correct size to get. You may be able to fit all kinds of sizes, for example, a trailer that uses 14” wheels can probably fit 13” wheels.

Q: How to identify trailer tires?

A: Trailer tires are designated as “ST” tires (Special Tire). Your tire size will start with "ST."

Q: How is wheel size calculated?

A: The wheel size is the size designation of a wheel given by its diameter, width, and offset. The diameter of the wheel is the diameter of the cylindrical surface on which the tire bead rides. The width is the inside distance between the bead seat faces.

Q: What is the spacing on trailer wheels?

A: Most trailers on the road have a 4, 5 or 6 Lug pattern. A very common designation for a trailer wheel would be 5 on 4.5. This means that the hub has 5 bolts spaced evenly on a 4-1/2" circle.

Q: Are trailer wheels tubeless?

A: They are less common today due to the prevalence of tubeless tire technology but if you are unsure whether your trailer requires an inner tube, check with the trailer manufacturer's guidelines.

Q: What does D mean on trailer tires?

A: For a tire with a 14” diameter, you don't want to have a load capacity much heavier than 2,000 pounds per tire. D range tires are a bit more heavy duty than C range tires and are more suitable for larger open trailers or enclosed cargo trailers.

Q: How many ply are trailer tires?

A: Standard ply ratings for trailer tires range from 6 to 10, although higher ratings are available for specialized applications.

Q: Where is tire pressure on trailer?

A: Trailer tires can look fully inflated and be below the safe air pressure. Find the maximum tire pressure by looking at your tire sidewall. Look for the small notation “Max. Load” followed by a PSI number (80 in the example below).

Q: What is the tire pressure for a trailer?

A: This can usually be found on the tire sidewall or in the trailer's owner's manual. For a camper trailer weighing 1800kg with 16-inch mud tires, the optimal tire pressure may be around 35-45 psi (pounds per square inch). This pressure provides good stability, fuel efficiency, and tire wear.

Q: What are trailer wheels made of?

A: Constructed from the highest grades of steel and aluminum, our heavy-duty wheels are able to take on more carrying capacity, while performing at the highest standards.

Q: What is the temperature of trailer tires?

A: The typical tire should run about 158 degrees (Farenheidt) once you get going down the road, but this can vary greatly depending on the weight of the trailer, how fast you're traveling, and also driving habits.

Q: How long will trailer tires last?

A: As a general rule of thumb, consider replacing trailer tires every 3 to 5 years, even if they appear to have sufficient tread. Regularly inspect your tires for signs of wear, such as uneven tread or sidewall damage, and replace them if you notice any issues.

Q: When to replace trailer wheels?

A: Look at tire treads for signs of uneven wear patterns. As a general rule of thumb, your tires should be replaced when the tread is worn down to 2/32 of an inch. Tires do have built-in tread wear indicators to help you realize when it is time to replace them.
