Your Guide to Choosing the Best 37-Inch All-Terrain Tires
You are ready to upgrade your ride! 37-inch tires look tough and handle rough trails. But picking the right set takes some know-how. This guide helps you find the perfect 37-inch all-terrain (A/T) tires for your truck or SUV.
Key Features to Look For
When you shop for these big tires, look closely at these important parts:
- Tread Pattern: This is the design on the tire’s surface. A good A/T tire needs deep, wide grooves. These grooves help push away mud, water, and small rocks.
- Sidewall Strength: The side of the tire needs to be tough. Strong sidewalls prevent punctures when you drive over sharp rocks or sticks off-road. Look for tires with three-ply construction if you plan serious off-roading.
- Load Range (Load Index): This number tells you how much weight the tire can safely carry. Since 37-inch tires are heavy, make sure the load range matches or exceeds your vehicle’s needs, especially if you tow heavy trailers.
- Speed Rating: This letter code shows the maximum safe speed. Most A/T tires have lower speed ratings than street tires. Check if it meets your normal highway driving speed.
Important Materials Matter
Tire quality starts with what they use to build them. Most 37-inch A/T tires use a mix of rubber compounds and internal belts.
- Rubber Compound: Softer rubber grips better on rocks but wears out faster. Harder rubber lasts longer on the highway but might slip on wet surfaces. Good A/T tires balance these two things.
- Carcass Construction: This is the internal structure. High-quality tires use strong polyester or nylon cords for the body. Steel belts add puncture resistance under the tread.
Factors That Improve or Reduce Tire Quality
Not all 37-inch tires perform the same way. Some features boost performance, while others hurt it.
What Makes Quality Better?
- Self-Cleaning Voids: Tires with big gaps (voids) between the tread blocks clean themselves out quickly. This keeps the tire gripping the ground, not just spinning in mud.
- Stone Ejectors: These small rubber bumps sit in the grooves. They push out small stones before they can get stuck and damage the tire.
- UTQG Rating: The Uniform Tire Quality Grading system gives a score for treadwear. A higher number (like 500 vs. 300) means the tire should last longer.
What Can Lower Quality?
- Low Ply Rating: If the sidewall only has two plies instead of three, it punctures easily off-road.
- Too Much Siping: Siping refers to the small slits cut into the tread blocks. Too many small slits make the tread blocks squirmy on the road, which reduces handling and tire life.
- Aggressive Mud Design: If you buy a tire that looks too much like a mud-terrain (M/T) tire, it will be noisy and wear out fast on pavement.
User Experience and Common Use Cases
How you plan to use your truck decides which 37-inch A/T tire you should buy. These tires are big, so they usually need a lift kit on your vehicle.
Everyday Driver (Light Off-Road Use)
If you drive mostly on highways but want to handle snowy roads or easy dirt trails, look for tires marketed as “Hybrid A/T.” These offer a quiet ride and good fuel economy for their size. They balance road manners with light trail capability.
Weekend Adventurer (Moderate Off-Road Use)
This user tackles rocky fire roads and deeper mud puddles. You need a true A/T tire with reinforced sidewalls. Expect a bit more road noise than a street tire, but you gain excellent traction when the pavement ends.
Serious Overlander (Heavy Use)
If you spend weeks exploring remote areas, prioritize durability above all else. Choose tires with the highest load rating and three-ply sidewalls. Noise and fuel economy become secondary concerns compared to surviving sharp rocks.
10 Frequently Asked Questions About 37-Inch All-Terrain Tires
Q: What size vehicle usually fits 37-inch tires without major work?
A: Most full-size trucks (like Ford F-150, Chevy Silverado) and large SUVs (like Toyota Tundra, larger Jeep Wranglers) can fit 37-inch tires, but they almost always require a suspension lift kit, usually 4 inches or more.
Q: Are 37-inch A/T tires much heavier than stock tires?
A: Yes, they are significantly heavier. This extra weight slows down acceleration and can reduce your gas mileage by 1 to 3 miles per gallon.
Q: How much longer do 37-inch A/T tires last compared to standard highway tires?
A: It depends on the rubber compound. A good A/T tire might last 40,000 to 55,000 miles. Highway tires often last 60,000 miles or more, but they cannot handle rough terrain.
Q: Do these large tires make a lot of noise on the highway?
A: Yes, they are louder than regular tires. The blocky tread pattern creates more air resistance and noise. Look for “Quiet Ride Technology” if noise is a major concern.
Q: What is the most important thing to check before buying 37-inch tires?
A: You must check your vehicle’s maximum recommended tire size and ensure your suspension and fender space allow for the extra diameter and width.
Q: What does “All-Terrain” really mean compared to “Mud-Terrain”?
A: A/T tires are designed to be good on both pavement and dirt. M/T tires are specialized for deep mud and rocks; they perform poorly and loudly on smooth roads.
Q: Should I buy Load Range C, D, or E for my truck?
A: Load Range C is lighter duty. Load Range E (10-ply equivalent) is best for heavy trucks or those that tow often, offering the best puncture resistance.
Q: Does installing 37-inch tires require re-gearing the axle?
A: While not strictly required, re-gearing (changing the differential gears) is highly recommended. It helps your engine maintain power and reduces strain when accelerating with the bigger tires.
Q: How does the tread depth affect performance?
A: Deeper tread depth means better grip in soft conditions like snow or mud. However, very deep treads on A/T tires can sometimes cause the tread blocks to flex too much on the road.
Q: Are 37-inch tires more expensive than smaller A/T tires?
A: Yes, the price increases significantly with size. A set of 37-inch tires can cost 30% to 50% more than a comparable set of 33-inch or 35-inch tires.
