Dually trucks, also known as dual-rear-wheel (DRW) trucks, are the heavy-duty workhorses of the automotive world. They're built for serious towing and hauling, from transporting heavy equipment and livestock to pulling large trailers and campers. However, the unique configuration of two tires on each side of the rear axle presents specific challenges and considerations when it comes to tire selection. Choosing the right tires for your dually truck is crucial for safety, performance, fuel efficiency, and longevity. This comprehensive guide will walk you through everything you need to know to make an informed decision and ensure your dually is running smoothly and efficiently.
Why Tire Choice Matters for Dually Trucks
Best Tires For Dually Truck: A Comprehensive Guide to Choosing the Right Rubber
Unlike single-rear-wheel trucks, duallys distribute weight across a larger surface area, improving stability and load-carrying capacity. However, this also means that tire pressure and proper fitment are even more critical. Here's why:
- Load Capacity: Dually tires must be able to handle the considerable weight your truck is designed to carry. Overloading tires can lead to premature wear, tire failure, and dangerous blowouts.
- Tire Wear: Uneven tire wear is a common issue with duallys. Improper inflation, misalignment, and mismatched tires can all contribute to this problem.
- Handling and Stability: The right tires will provide optimal traction and stability, especially when towing or hauling heavy loads.
- Fuel Efficiency: Rolling resistance is a major factor in fuel consumption. Choosing fuel-efficient tires can save you money at the pump.
- Safety: Properly inflated and maintained tires are essential for safe driving, especially under heavy loads.
Understanding Tire Specifications
Before diving into specific tire recommendations, it's important to understand the key specifications found on the tire sidewall.
- Tire Size: This is the most critical specification. For example, LT235/85R16 indicates a Light Truck (LT) tire, with a section width of 235 millimeters, an aspect ratio of 85 (sidewall height as a percentage of section width), Radial (R) construction, and a rim diameter of 16 inches. Always adhere to the tire size recommended by your truck manufacturer.
- Load Range (or Ply Rating): This indicates the tire's load-carrying capacity. Common load ranges for dually trucks are E (10-ply rated) and F (12-ply rated). Higher load ranges can handle more weight. Check your truck's door jamb sticker for the recommended load range.
- Load Index: A numerical code that corresponds to the maximum weight a single tire can carry at its maximum inflation pressure.
- Speed Rating: An alphabetical code indicating the maximum speed at which the tire is designed to operate.
- Treadwear Rating: A relative rating indicating the tire's expected lifespan compared to a standard reference tire. A higher number suggests a longer lifespan.
- Traction Rating: An alphabetical rating (AA, A, B, C) indicating the tire's ability to stop on wet pavement. AA is the highest rating.
- Temperature Rating: An alphabetical rating (A, B, C) indicating the tire's resistance to heat buildup. A is the highest rating.
- DOT Code: Indicates the tire's date of manufacture. Avoid purchasing tires that are several years old.
Types of Tires for Dually Trucks
The best type of tire for your dually depends on your driving conditions and needs. Here's a breakdown of common options:
- Highway Tires: Designed for smooth, quiet rides and long tread life on paved roads. They typically offer good fuel efficiency. Ideal for drivers who primarily use their dually for commuting and light towing.
- All-Terrain Tires: A versatile option that balances on-road comfort with off-road capability. They provide better traction on gravel, dirt, and snow than highway tires. A good choice for drivers who occasionally venture off-pavement.
- Mud-Terrain Tires: Designed for extreme off-road conditions, with aggressive tread patterns for maximum traction in mud, rocks, and snow. They tend to be noisy on the highway and wear more quickly than other types.
- Commercial Tires: Specifically designed for heavy-duty use and long-distance hauling. They often feature reinforced construction and durable compounds for extended tread life.
Factors to Consider When Choosing Tires
Beyond the type of tire, consider these factors when making your selection:
- Load Requirements: Determine the maximum weight you'll be carrying or towing. Choose tires with a load range and load index that meets or exceeds your needs.
- Driving Conditions: Consider the types of roads you'll be driving on (highway, gravel, dirt, snow).
- Climate: If you live in an area with severe winter weather, consider tires with the "3 Peak Mountain Snowflake" symbol, indicating they meet specific snow traction requirements.
- Budget: Tire prices vary widely. Balance your needs with your budget.
- Tire Reviews: Research online reviews to see what other dually owners are saying about different tire brands and models.

Maintaining Your Dually Tires
Proper tire maintenance is essential for safety, performance, and longevity.
- Check Tire Pressure Regularly: Use a reliable tire pressure gauge and inflate your tires to the recommended pressure (found on your truck's door jamb sticker or in the owner's manual). Check tire pressure at least once a month and before any long trips.
- Rotate Your Tires: Regular tire rotation helps ensure even wear. Consult your owner's manual for the recommended rotation pattern.
- Inspect Your Tires Regularly: Look for signs of wear, damage, or uneven wear patterns.
- Get Your Wheels Aligned: Proper wheel alignment is crucial for even tire wear and optimal handling.
- Balance Your Tires: Balanced tires provide a smoother ride and reduce vibration.
- Avoid Overloading Your Truck: Exceeding your truck's weight limits can damage your tires and compromise safety.
Potential Challenges and Solutions
- Uneven Tire Wear: Ensure proper inflation, regular tire rotation, and proper wheel alignment.
- Tire Rubbing: If you're running larger-than-stock tires, they may rub against the wheel wells or suspension components. Consider using wheel spacers or a leveling kit to provide more clearance.
- Finding the Right Tire Pressure: Experiment with different tire pressures to find the optimal balance between ride comfort, handling, and fuel efficiency.
