Trucks and SUVs are built for adventure, but venturing off-road requires the right equipment. One of the most crucial decisions you’ll make is selecting a set of 40×13.50R17 tires that can handle the demanding terrain you’ll encounter. These massive tires offer superior ground clearance, improved handling, and aggressive tread patterns for unmatched traction. Whether you’re a seasoned off-roader or just starting to explore the unbeaten path, this guide will equip you with the knowledge to make an informed decision.
Understanding 40×13.50R17 Tires: Size and Specifications Explained
Before diving into specific features, let’s break down the cryptic code that defines a 40×13.50R17 tire size:
- 40: This represents the overall diameter of the tire in inches, from the tread surface to the top of the sidewall.
- 13.50: This indicates the section width of the tire in inches, which is essentially the width from sidewall to sidewall.
- R: This stands for “radial” construction, the most common tire design for passenger vehicles and light trucks.
- 17: This represents the diameter of the tire’s bead (the inner ring that fits onto the wheel) in inches.
When selecting 40×13.50R17 tires, it’s crucial to ensure they fit your vehicle’s wheels and suspension system. Installing oversized tires may necessitate modifications to prevent rubbing or contact with the fenders. Consulting a tire professional or your vehicle’s manual is recommended to confirm proper fitment.
Key Considerations When Choosing 40×13.50R17 Tires
With a variety of 40×13.50R17 tire options available, consider these key factors to narrow down your selection and find the perfect match for your needs:
- Terrain: Where will you be using your tires most often? Mud-terrain (M/T) tires excel in off-road situations with loose dirt, rocks, and mud. All-terrain (A/T) tires provide a good balance of on-road and off-road performance. If you primarily drive on pavement, highway terrain (H/T) tires prioritize comfort and fuel efficiency.
- Weather Conditions: Do you encounter frequent rain or snow? If so, consider M/T or A/T tires with deeper treads and siping (tiny slits) for improved traction in wet weather.
- Driving Style: If you’re an aggressive off-roader, prioritize M/T tires with aggressive sidewall lugs for maximum grip on uneven surfaces. For a smoother ride and better fuel economy, A/T or H/T tires might be more suitable.
- Load Rating: This refers to the weight a tire can safely carry. LT (Light Truck) construction is common for 40×13.50R17 tires and is suitable for most trucks and SUVs. However, if you haul heavy loads regularly, consider tires with a higher load rating.
Top Features of 40×13.50R17 Tires for Off-Road Performance
40×13.50R17 tires excel in off-road environments due to several key features:
- Aggressive Tread Patterns: Deep lugs with wide spacing bite into loose dirt, rocks, and mud for superior traction. These treads also help self-clean by ejecting mud and debris as the tire rotates.
- Sidewall Protection: Reinforced sidewalls with thicker rubber compounds provide additional protection against punctures and abrasions from rocks and other sharp objects encountered off-road.
- Durability: 40×13.50R17 tires are typically constructed with multiple plies and thicker sidewalls to withstand the harshest off-road conditions. Many M/T tires also feature puncture-resistant compounds to minimize the risk of flats.
- Large Diameter: The increased diameter of 40×13.50R17 tires provides greater ground clearance, allowing you to navigate over obstacles and uneven terrain more easily.
Popular 40×13.50R17 Tire Options and Reviews
Here’s a glimpse into some of the most popular 40×13.50R17 tire options available, along with their strengths and considerations:
- Cooper Discoverer STT Pro: This legendary off-road tire features Kevlar sidewall reinforcement for puncture resistance and durability. It delivers impressive grip in mud, rocks, and loose dirt. However, Wrangler MT/Rs can be noisy on pavement and have a lower fuel economy rating compared to all-terrain tires.
- Toyo Open Country M/T: A favorite among off-road enthusiasts, the Open Country M/T is renowned for its long tread life and aggressive mud terrain performance. It features a high turn-up construction for excellent durability and impact resistance. While an excellent off-road tire, Open Country M/Ts can be stiff on pavement.
- Yokohama Geolandar M/T G003: This tire strikes a good balance between off-road capability and on-road comfort. Yokohama’s Geo-Shield technology enhances durability and provides exceptional traction in various terrains. However, some users report that Geolandar M/T G003 tires wear slightly faster than some competitors.
- Nitto Trail Grappler M/T: This all-around performer offers impressive off-road prowess without sacrificing on-road comfort and noise levels. Trail Grappler M/Ts are known for their balanced performance and long tread life. They may not be the most aggressive option for hardcore mud terrains, but they excel in most off-road conditions.
Remember, these are just a few examples, and numerous other 40×13.50R17 tire options cater to various needs and budgets. Researching and comparing different tires is crucial to find the perfect match for your specific vehicle and driving style.
Beyond the Basics: Additional Considerations for Off-Road Tires
Once you’ve narrowed down your choices based on terrain, driving style, and budget, consider these additional factors:
- Load Capacity: Ensure the tires have a sufficient load rating to handle the weight of your vehicle and any cargo you typically haul.
- Speed Rating: While not as critical for off-road driving, consider the speed rating of the tires. Most 40×13.50R17 tires are designed for moderate highway speeds.
- Warranty: Check the tire warranty for coverage on tread wear, punctures, and road hazards. A good warranty provides peace of mind knowing you’re protected against unexpected damage.
Upgrading Your Wheels for 40×13.50R17 Tires
Installing 40×13.50R17 tires may necessitate upgrading your wheels to accommodate the larger size. Here are some factors to keep in mind when selecting wheels:
- Wheel Diameter: Ensure the wheel diameter matches the 17-inch diameter of the tires.
- Width: Wider wheels can enhance stability and provide a more aggressive stance. However, excessively wide wheels might cause rubbing against the fenders.
- Offset: The offset refers to the distance between the wheel’s mounting surface and its centerline. The correct offset is crucial for proper fitment and to avoid any rubbing issues.
- Material: Steel wheels are a durable and affordable option, while alloy wheels offer a lighter weight and a more stylish look.
Consulting a professional installer or using a wheel fitment guide can help you select the perfect wheels for your vehicle and ensure proper fitment with your new 40×13.50R17 tires.

Don’t Get Stuck in the Mud: Essential Tips for Maintaining Your Tires
Once you’ve invested in a set of impressive 40×13.50R17 tires, proper maintenance is crucial to maximize their performance, lifespan, and safety. Here are some essential tips to keep your off-road tires in top shape:
- Regular Inspections: Visually inspect your tires weekly for any signs of damage, such as cuts, punctures, or uneven tread wear. Remove any rocks or debris lodged in the tread that could cause punctures or irregular wear.
- Proper Inflation: Maintain the recommended tire pressure as specified in your vehicle’s owner’s manual or on the tire placard located on the driver’s side door jamb. Underinflated tires can lead to increased wear, handling issues, and poor fuel economy.
- Tire Rotation: Regular tire rotation is essential for even tread wear. Rotate your tires every 5,000 miles according to the manufacturer’s recommendations or your vehicle’s service manual.
- Alignment: Wheel alignment ensures your tires contact the road surface at the optimal angle. Misalignment can cause premature and uneven tread wear, as well as affect handling. Get your wheels aligned whenever you install new tires or experience any pulling or vibration while driving.
- Balancing: Tire imbalance can cause vibrations at higher speeds and lead to uneven tread wear. Have your tires balanced regularly, especially after hitting potholes or curbs, or whenever you experience a vibration.
By following these simple maintenance practices, you can extend the life of your 40×13.50R17 tires and ensure optimal performance on and off the road.
