When it comes to trailer tires, one of the most common questions people ask is: what’s the difference between bias and radial trailer tires? If you’re new to trailer tires, you might be a little confused. But don’t worry, we’ll answer that in an easy to understand way.
What is a bias ply trailer tire?
A bias ply trailer tire is made by layering rubber fabric at a diagonal angle. These layers are crisscrossed longitudinally and horizontally, creating a “bias-cross” pattern. This construction gives the bias ply tire a harder sidewall and a stronger structure.
Why choose a bias ply tire?
Great for Smaller Trailers: Bias ply tires are typically used on smaller trailers such as utility trailers, campers, and some older models.
More affordable: They tend to be cheaper than radial tires, so if you’re on a tight budget, bias ply tires may be the best choice for you.
Durable for short hauls: These tires are good for trailers that don’t need to travel long distances or at high speeds, such as local trips or hauling lighter loads.
Disadvantages of bias ply tires:
Less Smooth Ride: Compared to radial tires, bias-ply tires have stiffer sidewalls, which results in more vibration and a bumpier ride.
Faster wear: If you tow long distances or drive at high speeds often, you may find that bias-ply tires wear out faster than radials.
What are radial trailer tires?
Radial trailer tires have a unique structure. The layers of fibers in a tire are aligned at a 90 degree angle (perpendicular) to the tread. This makes the sidewalls of radial tires more flexible and the tread stronger.
Why choose radial tires?
Better Ride: Radial tires provide a smoother ride, better traction and better handling, especially at high speeds.
Longer life: Radial tires are designed to wear more evenly, so they tend to last longer than bias-ply tires.
Improved Fuel Efficiency: Radial tires have more flexible sidewalls that reduce rolling resistance, which means they use less fuel while towing.
Great for long trips: Radial trailer tires are a good choice if you’re going on long trips or hauling heavy loads.
Disadvantages of radial tires:
Higher cost: Radial tires tend to cost more than bias-ply tires, though they usually last longer, making them a good long-term investment.
Not good for low-speed towing: If you tow at lower speeds or only use a trailer for short trips, the advantages of radial tires may not be as apparent.
Which should you choose? Bias or radial tires?
Choosing bias or radial trailer tires depends on how you plan to use your trailer. Here’s a quick comparison to help you decide:
Bias tires are best for:
Small trailers or light trailers
Occasional use or local transportation
Buyers on a budget who don’t need long-distance performance
Radial tires are best for
Heavy duty trailers or long distance hauling
Highway highway driving
Frequently hauling large or heavy loads
Those looking for better performance, durability and fuel efficiency
How do I know which tires are right for my trailer?
If you’re still not sure, the best thing to do is check your trailer manual or look at your existing tires. You’ll find the size and specifications clearly listed on the side of the tire, including the type of tire (bias ply or radial).
For example, if your trailer requires 205/75R15 tires, you’ll see them marked on the sidewall. If you want a smooth ride on long trips or heavy loads, radial tires like 205/75R15 are a good choice.
Checking the condition of trailer tires
In addition to whether you choose bias or radial tires, it’s important to check the condition of your tires on a regular basis. Look out for the following
Cracks or bulges in the sidewalls
Uneven or worn tread
Tire pressure that is too low
If you notice any of these issues, it’s time to replace your tires. Don’t risk a blowout or uneven wear, and always make sure your trailer is equipped with tires that are in good condition.
Where to Buy the Best Trailer Tires
Whether you need bias ply or radial trailer tires, it’s important to choose high-quality tires that fit your trailer’s specifications. You can find 205/75R15 trailer tires or other sizes from trusted tire suppliers or our-store. Be sure to check
Load rating: Make sure the tires can safely carry the weight of the trailer and its cargo.
Durability: Look for tires that are designed to handle the specific conditions of your trailer.
Warranty: A good tire brand will offer a warranty for added peace of mind.
