Biggest Dually Tire Without Spacer – What Are The Choices?

If you want to know the biggest tire size your Dually truck can hold without using a wheel spacer, look no further. We researched the exact tire dimensions so you won't compromise your truck's maneuverability, accelerate component wear and tear, and avoid the risk of fender damage.

255/85/16r tires are the most recommended option. Anything bigger may require installing a wheel spacer to make the tires fit.

A wheel spacer will allow you to get the perfect fit and alignment for your truck, which is crucial for handling and safety on the road. 

A properly sized tire will not only provide better traction on the road but also make a better rolling radius. This is especially true for big trucks that have wide wheels. However, wheel spacers are tempting truck owners to use bigger tires because they think that "bigger is better".

Is this true? Continue reading as we investigate further if this is a fact or just an opinion.

Pros and Cons of Bigger Dually Truck Tires: Is Bigger Better?

"The bigger, the better" is the slogan that comes to mind when someone asks about big tires. We'll discuss the pros and cons of larger truck tires to help you decide which size is right for your needs.


1. Cool factor

There is no doubt that a bigger tire makes a vehicle look bigger and more imposing. But you must remember that you should be able to control the vehicle using the manufacturer's recommended tires.

A larger tire will not only make the vehicle look bigger but will also make it harder to steer.

2. Increased road handling

Bigger tires are one of the best ways to improve handling in trucks. When you put bigger tires on your truck, you can turn tighter corners and maintain more control of the vehicle.

The bigger the tire, the better the handling because you will have more traction. However, there are some disadvantages that come with bigger tires. They increase the weight of the truck. However, this is balanced out by the fact that they make the vehicle more stable.

Vehicle tires can affect how the vehicle drives, but some people wonder whether larger tires will make a difference. There are different reasons for buying a larger tire.

For example, if you plan on using the truck for towing or hauling a heavy load, it might be a good idea to get a larger tire.

You can also get a larger tire if you are planning on driving off-road or if you plan on doing off-road work. It can also be a good idea if you drive on dirt roads or in the country.


1. Loss of suspension

When buying tires, you should know that bigger tires are heavier and can reduce the suspension's efficiency. In the past, people thought that bigger tires were the best choice, but nowadays, the manufacturers don't recommend other than the factory default.

In addition, bigger tires have a larger footprint, meaning that they leave larger marks in the dirt and mud. This is why these trucks require bigger suspension systems to handle the extra weight.

Plus-sizing your tires would mean additional stress to the suspension system. Hence, it's better to go with the factory-recommended size for safety reasons and also to avoid premature breakdown of the suspension system.

2. Reduced free-wheeling time

Many trucks and SUVs come equipped with bigger tires. They are considered for their off-road capability and ability to handle a lot of weight.

But there is a downside to this. Bigger tires are heavier, so you will spend more time turning the steering wheel. This may mean you will lose free-wheeling time and maneuverability.

Theoretically, the wheel's size is directly proportional to the time required to keep it moving without stepping on the gas pedal.

Is A Dually Truck Good In Snow?

When the snow falls, it accumulates on the pavement or ground. A vehicle equipped with dual rear wheels like a dually can maintain traction by applying more force to each wheel.

Single-tire vehicles have a weaker grip in the snow and are more likely to slide off the road.

Why Do Duallys Have Two Rear Wheels?

The dual rear wheel configuration allows for better traction and stability, especially when towing heavier loads. A single rear wheel would put more weight on the back axle of the truck, which would cause the truck to veer off the road.

Can You Drive A Dually Off-Road?

A dually pickup truck with a heavy-duty engine is an excellent workhorse. It can handle a great deal of abuse and be depended on in the toughest of conditions.

However, some people want to take the best parts of a truck and make it into an off-roader. It doesn't take long for this to happen.

Duallys were originally designed as a pickup truck. However, they came into being as custom vehicles, and some have taken them to another level.

These off-roaders are designed to handle the demands of off-road driving. They can be modified to handle anything you throw at them.

If you want to build one of these duallys, you'll need to ensure that you have the proper components and skills. You can find a few things you can check out to ensure that you have the tools and experience to build a truck that can handle the road conditions you're dealing with.

First, you'll want to get some heavy-duty suspension components. These parts will give your truck the ability to get over the bumps and rocks you encounter on the road. And you'll need a suspension lift kit to be able to raise the truck's front end, giving it more clearance to get over obstacles.

Can You Increase Payload Capacity By Upgrading Springs In A Dually?

As a truck driver, you'll be using the trailer of your rig to haul loads. As you transport goods in the trailer, you must ensure the trailer is adequately secured to the vehicle. The stability of the load depends on the strength and condition of the rear springs.

As the weight of the load increases, the axle becomes unstable. And so, you'll have to reinforce the axle to maintain stability. This can be achieved by increasing the springs' strength.

When a spring fails, a load is transferred onto the remaining springs. This can cause the rear axle to deflect, thereby decreasing the amount of cargo that can be carried.

What Will Happen If You Exceed Load Capacity?

When you go over the payload capacity of your trailer, you increase the load capacity beyond what your vehicle was designed for. You might think that your vehicle can handle a heavy load, but it can only take so much weight before it starts to break down.

Your payload is the maximum weight you can take in a single trip. To know if your vehicle can handle a heavier load, here are some guidelines to follow:

  • Look at the manufacturer's specifications to see what it says about its maximum capacity
  • Contact the dealership you bought the trailer from. They may have an additional warranty for heavy-duty vehicles
  • Look at other trucks of the same make and model you bought. See if they have more or less payload capacity.

In addition, overloading is a serious issue that causes a lot of trouble. It affects the driver, passengers, and even the cargo.

Truck overloading can be dangerous because the truck can tip over if the load shifts. This could result in accidents and injuries.

To prevent your truck from being overloaded, keep these guidelines in mind:

  • Make sure you don't exceed the maximum gross weight of the truck
  • Do not stack the cargo on top of the truck
  • Do not overload the trailer

How Do You Know If Your Dually Is Overloaded?

There are several ways to determine if your vehicle is overloaded. If you have a rearview mirror, you can use it to check whether your vehicle is carrying too much weight.

One of the best indicators of an overloaded vehicle is slow acceleration or braking. Another sign is a swaying or jerking motion of the vehicle when you hit bumps or dips.

When you are towing a trailer behind a truck, you can tell if the truck is overloaded if you notice that the front end of the trailer drifts to the left or the right.

If the front of the trailer leans left or right, it means that the vehicle is overloaded. The problem is that if the trailer's front is leaning to the left or right, the load is too heavy for the hitch and the tires to support.

This is dangerous because if the tires begin to skid, the vehicle could lose control and crash.

In Closing

Yes, bigger tires are great for improving traction and handling. Larger tires are more stable on the road. The downside of using bigger tires is the increased rolling resistance.
