Understanding Tire Sizing for Dually Trucks

Before we delve into the specifics of "311 5016," it’s crucial to understand how tire sizes are typically expressed and what factors are paramount for dually applications. Standard passenger and light truck tire sizes follow a common format, for example: LT265/70R17.

• LT: Light Truck designation, indicating the tire is built for heavier loads.
• 265: Section Width (in millimeters). This is the width of the tire from sidewall to sidewall at its widest point.
• 70: Aspect Ratio (percentage). This is the height of the sidewall as a percentage of the section width. In this case, the sidewall height is 70% of 265mm.
• R: Radial construction.
• 17: Rim Diameter (in inches). The diameter of the wheel the tire is designed to fit.

Dually trucks, with their dual rear wheels, have unique fitment challenges. The primary concern is ensuring sufficient clearance not only between the tire and the fender but also, crucially, between the two tires on each side of the rear axle. Standard dually tires are typically designed to maintain a specific gap for proper cooling and to prevent rubbing under load. Common dually sizes often range from 235/80R17 to 265/70R17, sometimes even 19.5-inch commercial tires for heavier applications.

Key Fitment Considerations for Dually Trucks

When contemplating any tire size beyond the factory specifications for a dually, several critical factors must be rigorously evaluated:

1. Fender Clearance (Inner & Outer):

   • Outer Fender: Is there enough space between the tire’s outer sidewall and the edge of the fender? Wider tires can protrude, leading to rubbing during suspension compression or turning.
   • Inner Fender/Wheel Well: Does the tire clear the inner wheel well, frame, and suspension components, especially when the steering wheel is at full lock (for front tires) or the suspension is compressed?

   

2. Dual Wheel Spacing (Rear Axle Critical): This is arguably the most important factor for duallies. There must be adequate space between the two tires on each side of the rear axle.

   • Rubbing Risk: If the tires are too close, they will rub against each other, especially when carrying a heavy load or cornering. This generates excessive heat, leading to premature tire wear, potential sidewall failure, and even catastrophic blowouts.
   • Heat Dissipation: Proper spacing allows airflow for cooling, which is essential for load-carrying tires.

3. Load Capacity (Load Index): Dually trucks are designed to haul and tow heavy loads. Any replacement tire must meet or exceed the vehicle’s Gross Axle Weight Rating (GAWR). A tire’s Load Index indicates its maximum load capacity. Installing tires with insufficient load capacity is a serious safety hazard.

4. Brake and Suspension Components: Larger tires, especially those with different backspacing on their wheels, can interfere with brake calipers, steering knuckles, tie rods, and suspension arms.

5. Speedometer and Odometer Calibration: Changing the overall diameter of your tires will affect the accuracy of your speedometer and odometer. A larger diameter tire will make your speedometer read slower than your actual speed, and your odometer will log fewer miles than traveled.

6. Traction Control and ABS Systems: Modern vehicles rely on accurate wheel speed readings. Significant changes in tire diameter can confuse these systems, leading to erratic behavior or fault codes.

Analyzing the "311 5016" Fitment Hypothetically

Let’s break down the hypothetical "311 5016" tire size and its implications for a dually:

• 311mm Section Width: This is a very wide tire for a dually application, especially on the rear axle. Standard dually tires are typically in the 235mm to 265mm range. A 311mm width would almost certainly cause severe rubbing between the dual tires without significant modifications, and likely outer fender clearance issues as well.
• 50% Aspect Ratio: This indicates a very low-profile tire. For a truck, particularly a dually, a low-profile tire is highly unusual.
  • Load Capacity Concern: Low-profile tires generally have shorter sidewalls, which can limit their load-carrying capacity compared to taller, more traditional truck tires. This is a critical concern for a heavy-duty dually.
  • Ride Quality: A low aspect ratio typically results in a harsher ride, which is undesirable for a work truck.
  • Vulnerability: Shorter sidewalls are more prone to damage from potholes or off-road obstacles.
• 16-inch Rim Diameter: While 16-inch rims were common on older trucks, many modern duallies use 17-inch, 18-inch, or even 19.5-inch rims to accommodate larger brakes and higher load capacities. Finding a high-load-rated tire with a 311mm width and a 50% aspect ratio for a 16-inch rim would be exceptionally difficult, if not impossible, as this combination is not typical for heavy-duty applications.

Conclusion on "311 5016" Fitment:
Based on this analysis, it is highly improbable that a "311 5016" tire (interpreting it as 311/50R16) would fit a dually pickup truck without extensive and costly modifications. The width is problematic for dual spacing, the low profile is unsuitable for a work truck’s load and ride quality, and the combination of these with a 16-inch rim is not a common or practical configuration for dually tires.

Modifications Required for Non-Standard Fitment

If one were determined to fit such a non-standard tire, the following modifications would likely be necessary, each with its own costs and implications:

• Lift Kits/Leveling Kits: To increase fender clearance, especially for the front tires when turning. This doesn’t solve the dual tire spacing issue.
• Wheel Spacers/Adapters: To push the wheels further out from the hub, potentially creating more space between the dual tires. CAUTION: Wheel spacers can be controversial. High-quality, hub-centric spacers are essential, but they add stress to wheel bearings and studs, potentially compromising safety and reliability, especially on a heavy-duty truck. They also further push the tire out, exacerbating outer fender clearance issues.
• Aftermarket Wheels: Custom wheels with a specific offset and backspacing designed to accommodate wider tires while maintaining dual spacing. This is often the safest and most effective solution for wide tires, but it’s expensive.
• Fender Flares/Trimming: To cover the tires that protrude beyond the fender or to create additional clearance.
• Steering Component Upgrades: Larger, heavier tires can put additional strain on steering components, necessitating upgrades for durability and proper handling.
• Speedometer Calibrator: Essential to correct speedometer and odometer readings.

Safety and Performance Implications

Attempting to force an unsuitable tire size onto a dually can lead to severe safety and performance issues:

• Tire Rubbing & Heat Buildup: The most critical concern for duallies. Constant rubbing generates extreme heat, leading to premature wear, ply separation, and high risk of catastrophic tire failure.
• Reduced Towing/Hauling Capacity: If the installed tires do not meet the vehicle’s load capacity requirements, the truck’s ability to safely tow and haul will be compromised.
• Handling Changes: Larger, wider, or differently offset tires can negatively impact steering response, braking performance, and overall vehicle stability.
• Accelerated Component Wear: Increased stress on wheel bearings, suspension components, and steering linkage due to altered geometry and heavier rotating mass.
• Warranty Issues: Modifications to accommodate non-standard tires can void parts of your vehicle’s factory warranty.
• Legality: Some jurisdictions have regulations regarding tire protrusion beyond fenders or overall vehicle width.

Practical Advice for Dually Owners

1. Prioritize Safety and Functionality: A dually is a workhorse. Its primary purpose is to safely and efficiently transport heavy loads. Aesthetics should never compromise safety or capability.
2. Measure, Measure, Measure: Before purchasing any non-standard tires or wheels, meticulously measure all clearances (fender, inner wheel well, between duals) at various suspension compressions.
3. Consult Professionals: Talk to reputable tire shops specializing in truck tires and custom wheel fitment. They have experience and tools to assess compatibility.
4. Research Specific Truck Models: Fitment varies significantly between different truck makes, models, and even trim levels. What fits one dually might not fit another.
5. Understand Load Ratings: Always ensure any replacement tire meets or exceeds the vehicle’s GAWR for both axles.
6. Consider the Purpose: If your dually is a dedicated work truck, stick to proven, robust tire sizes designed for load and durability. If it’s a show truck, be prepared for significant modifications and potential compromises in functionality.

Frequently Asked Questions (FAQ)

Q1: What does "311 5016" mean as a tire size?
A1: "311 5016" is not a standard or recognized tire size format. In this article, we interpret it hypothetically as a tire with a 311mm section width, a 50% aspect ratio, and designed for a 16-inch rim (i.e., 311/50R16).

Q2: Why is a 311mm wide tire problematic for a dually?
A2: 311mm is exceptionally wide for a dually. The primary issue is maintaining sufficient clearance between the two tires on each side of the rear axle. This width would almost certainly lead to severe rubbing, heat buildup, and premature tire failure without significant and potentially unsafe modifications.

Q3: Can I just use wheel spacers to make wide tires fit on my dually?
A3: While wheel spacers can create more room, they are generally not recommended for heavy-duty dually applications, especially when pushing tires out significantly. They add stress to wheel bearings and studs, and if not hub-centric and high-quality, can lead to vibrations, premature wear, or even wheel separation. Aftermarket wheels with proper offset are a safer but more expensive alternative.

Q4: What’s the biggest tire I can fit on my dually without modifications?
A4: This varies greatly by truck make, model, and year. Generally, most duallies can go up one tire size (e.g., from 235/80R17 to 245/75R17) without issues, as long as the overall diameter and width are only marginally larger. Always check your specific truck’s clearances and consult forums or professionals for proven fitments.

Q5: Will changing my tire size affect my truck’s towing capacity?
A5: Yes, if the new tires do not have a sufficient load rating (Load Index) to meet or exceed your truck’s Gross Axle Weight Rating (GAWR), your effective towing and hauling capacity will be reduced, regardless of the truck’s factory rating. Always ensure your tires are rated for the loads you intend to carry.

Q6: What are the risks of tire rubbing on a dually?
A6: Tire rubbing generates extreme heat, which can cause tire plies to separate, leading to tire failure, blowouts, and potentially loss of vehicle control. It also rapidly wears down the sidewalls, reducing tire life.
