While trailer wheels may seem simple, they are highly technical components that have a significant impact on the performance and safety of the entire vehicle. In this extensive article, we will explore many of the critical factors that go into choosing a trailer wheel. From bead profiles to backspace, the details that follow will help you select the best wheels for your trailer.
Trailer rims are available in both aluminum and steel varieties. Aluminum is lighter, more corrosion resistant, and has better heat dissipation capabilities than steel. However, it is important to make sure that the trailer wheel weight capacity and hub size matches your trailer’s GAWR (Gross Axle Weight Rating) and hub size respectively. Failure to do so can result in cracked rims, costly repairs, and decreased payload capacity.
The hub side of the wheel is the surface that connects tilbehør til tilhenger with your trailer’s axle and braking system. It is essential that this surface has a precise and secure fit to avoid unwanted movement or misalignment. The hub face may be smooth, knurled, or lug-centric (meaning that the lugs attach to the hub in a specific pattern). The lug-centric design is typically preferred for most applications, as it is easy to mount tires and allows for more even tread wear.
In addition to the hub side of the wheel, the drum side is also important for braking performance. The proper match between the wheel’s bead profile and the trailer drum ensures that the tire has a good seal to prevent air leaks. The bead profile should be clearly marked on the wheel to assist in selecting the correct trailer wheel.
Another important aspect to consider is the speed rating of your trailer tire. This identifies the maximum safe speed at which the tire can be driven when properly inflated and loaded. Most light-duty trailer tires are rated at up to 75 mph, while heavy-duty trailer tires can be rated up to 87 mph.
For optimal handling, traction, and tread wear, it is recommended that you use the same tire sized and rated on both the left and right sides of your trailer. Mixing different tire brands, sizes, and tread patterns on opposite sides can negatively affect your trailer’s performance, stability, & braking efficiency.
The street side of the wheel is the part that faces the public, and it is important to choose a visually appealing option for your trailer, particularly in a commercial environment. The street side of the wheel should be properly aligned with your desired visual aesthetic to ensure that it is correctly mounted.
The offset of the trailer wheel is the distance between the mounting pad on the hub and the center line of the wheel. Careful selection of positive, zero, or negative offset will ensure that the wheel is in perfect alignment with your trailer’s hub, brake system, and tire size. Failure to do so can lead to improper tire installation and reduced performance. Be sure to check the manufacturer’s website for specifications regarding the wheel’s offset before making a purchase.
