Dually tires are an interesting ally of automotive engineering. Not only do they help provide more stability to heavy-duty vehicles, but the two sets of tires also give your ride a rugged look that can't be matched.

The space between the back tires should be at least 1/2 inch. This will help prevent the tires from wearing down too quickly and getting punctured. A popular choice for tire size on 6.5-inch wide dually wheels is 235/85R16.

But with such an unorthodox setup comes some confusion when it comes to tire sizes – how exactly do you pick the right ones? Don't worry – we've got your back! Here's all you need to know about dual tire sizes and choosing the best ones for your daily driver or off-road warrior.

Do Duallys Need Special Tires?

If you have a Dually truck, it's particularly essential to double-check that the tires fit correctly onto your rear axle. They must all be equivalent in make and size, as well as age if possible. In contrast, having back tires of two different heights will cause the bigger ones to endure more wear and tear – not evenly distributed!

It is important to make sure that all four tires on the rear axle are the same in make, size, and age. If the tires are of different heights, it can lead to uneven wear and faster tire wear. It is also important to make sure that the tires fit properly on the rear axle to ensure proper performance and handling of the vehicle.

What is the purpose of Dually tires? Dually tires are a type of tire that is used on vehicles with dual rear axles, also known as Dually trucks. The purpose of Dually tires is to provide increased capability and stability for towing and hauling heavy loads. The extra set of wheels allows for a higher maximum towing and payload capacity, making dually tires well-suited for use with 5th-wheel trailers or large, heavy hauls.

In addition, the extra wheels provide added stability in windy situations, which can improve safety when towing a trailer.

What cars use Dually tires?

Many drivers who need the extra traction, stability, and capacity of Dually tires opt for a pickup truck. The most common Dually cars are Ford F-250/350 Super Duty, Chevrolet Silverado, and GMC Sierra 2500/3500 HD trucks, as well as specialty models like the Dodge Ram 4500/5500. But it's not only pickups that use the dual tire setup – some recreational vehicles (RVs) like Class C motorhomes also have them.

No matter which vehicle you drive, understanding how to pick out the right size tires is key. Make sure you check your owner's manual or contact an expert before buying any new dually tires! That way, you can rest assured that your wheels are up to the task of hauling whatever the road throws your way.

Dually Tire Sizes

It is possible to fit 35-inch tires on a Ram Dually truck with a minimum 2-inch front leveling kit and 1/2-inch steel spacers between the duals. However, it is recommended to invest in a set of rims that do not require wheel spacers, as they can be prone to problems. It is also important to choose a tire brand that has a smaller side lug and a less aggressive tread pattern to prevent rubbing.

Toyo tires are known to be a good option for fitting well on a Ram Dually. On a stock suspension, the biggest tire size that can be squeezed onto a Ram 1500 may require some modifications, such as trimming the wheel well liner and sway bar and may cause rubbing on the radius bar fastener.

For optimal safety and handling on the road, a 255/85/16r tire is your best option. If larger tires are required, then installing a wheel spacer will allow you to achieve that perfect fit as well as alignment for your truck – an absolute must!

Wheels Spacers And Dually

Spacers can affect the wheel dynamics of a dually truck in a number of ways. One potential issue is that they alter the distribution of load on the hub, which can add strain on the studs and bearings. This is particularly problematic if the spacers are not fitted properly or if the vehicle is driven on uneven surfaces while carrying heavy loads or towing.

Another issue is that if the wheels are not seated correctly or fitted tightly against the hub, it can result in the studs carrying more of the load, which can lead to metal fatigue and premature failure. It is important to use hub-centric spacers to ensure that the wheels are centered properly and the studs are not carrying an excessive load.

Additionally, it is important to consider the load-carrying characteristics of the tires, as tires that are too close together may not have sufficient heat dissipation and are more vulnerable to blowouts. So, the hub-centric spacers, combined with the right type of tires, are necessary for a safe and reliable Dually truck setup.

Despite these potential issues, spacers can be a great way to get the perfect fit on your Dually truck, allowing you to customize it to your exact specifications and giving you peace of mind that all components are working together harmoniously. So don't be afraid to give them a try – just make sure you do some research first!

Final Thoughts

Overall, if you want to upgrade your Dually truck with larger tires or wheel spacers, make sure you do your research first to ensure that everything is installed correctly and safely. And don't forget to check the manufacturer's guidelines for tire size restrictions before purchasing any new tires! With proper knowledge and preparation, you should be able to fit whatever set of tires you need to get the perfect balance of looks, performance, and safety on your dually.

To ensure optimal performance and prevent premature tire wear and punctures, it is recommended to use a minimum spacer size of 1/2 inch (1.27 cm) between the rear dually tires. This will help to prevent small debris from getting stuck between the tires and will allow the tires to operate at their maximum load capacity. 235/85R16 tires are a popular choice for use on 6.5-inch wide factory stock dually wheels.
