The Ultimate Buying Guide for 37X12.50R20 All Terrain Tires
Choosing the right tires for your truck or SUV is a big deal. You need tires that handle highways well but can also conquer dirt roads. The size 37X12.50R20 tells us a lot. It means the tire is 37 inches tall, 12.5 inches wide, and fits a 20-inch wheel. This size is popular for lifted trucks. This guide helps you pick the best set.
Key Features to Look For
When shopping for these big tires, certain features matter most. These features determine how the tire performs in different weather and on different surfaces.
Tread Design and Depth
- Aggressive Lugs: Look for large, deep tread blocks (lugs). These dig into mud and loose dirt, giving you great traction off-road.
- Siping: These are small, thin slits cut into the tread blocks. Siping helps the tire grip icy or wet pavement better by creating extra biting edges.
- Void Ratio: This is the empty space between the tread blocks. A higher void ratio is better for mud clearing, but too much can make highway driving noisy.
Load and Speed Ratings
Always check the sidewall for the load index and speed rating. Since these tires are large, they often carry heavy loads. Ensure the load rating matches or exceeds what your vehicle needs, especially if you tow heavy trailers.
Important Materials That Build Quality
The stuff tires are made of directly affects how long they last and how they feel on the road.
Rubber Compound
All-terrain tires use a tough rubber mix. A good compound balances stickiness for grip with hardness for long life. Tires designed for extreme heat often have special additives to prevent cracking.
Sidewall Construction
The sidewall protects the tire from sharp rocks. Look for tires with a **3-ply polyester construction**. This heavy-duty construction resists punctures better than standard 2-ply tires. Strong sidewalls are crucial when airing down for off-roading.
Factors That Improve or Reduce Quality
Some things make a tire great; others make it just okay.
Factors That Improve Quality
- Three-Ply Sidewalls: As mentioned, this dramatically increases durability against trail hazards.
- Stone Ejectors: These small rubber bumps sit between the main tread blocks. They push out sharp rocks before they can get stuck and puncture the casing.
- UTQG Rating (Treadwear): A higher treadwear number generally means the tire will last longer on the highway.
Factors That Reduce Quality
Cheap tires often skimp on materials. Low-quality tires might use softer rubber to increase initial grip, but this means they wear out very fast. Also, poor internal construction can lead to vibrations or imbalances at highway speeds.
User Experience and Use Cases
How you plan to use your truck determines the best tire for you.
Highway Cruising (Commuting)
If 80% of your driving is on pavement, you want an AT tire that leans toward the highway side. These tires have tighter tread patterns. They offer a quieter ride and better fuel economy. They handle rain well but might struggle in deep mud.
Serious Off-Roading (Weekend Warrior)
If you spend weekends on trails, look for the most aggressive tread available in this size. You prioritize deep voids and rugged sidewalls over quiet highway noise. Expect these tires to wear faster on asphalt.
10 Frequently Asked Questions (FAQ) About 37X12.50R20 AT Tires
Q: Do 37-inch tires fit all trucks?
A: No. Most trucks need a lift kit, usually 4 inches or more, to fit 37-inch tires without rubbing the fenders or suspension components.
Q: Will these tires hurt my gas mileage?
A: Yes. Taller and wider tires weigh more and create more wind resistance. You will likely see a drop in miles per gallon (MPG).
Q: What is the best lifespan I can expect from a quality 37-inch AT tire?
A: A good set of all-terrain tires usually lasts between 40,000 and 60,000 miles, depending heavily on your driving style and rotation schedule.
Q: Are these tires noisy on the highway?
A: All-terrain tires are louder than street tires. However, newer designs use computer-optimized tread patterns to reduce road noise significantly compared to older models.
Q: What pressure should I run them at on the road?
A: Always start with the pressure listed on the sticker inside your driver’s side door jamb. For off-roading, you often lower the pressure, but never go below the manufacturer’s recommended minimum PSI.
Q: What does the “R” in the size mean?
A: The “R” stands for Radial construction. Almost all modern passenger and light truck tires are radial tires, which offer better flexibility and ride comfort.
Q: Do I need to balance my tires after installation?
A: Absolutely. Because these tires are large and heavy, proper balancing is essential to prevent vibrations that make driving uncomfortable.
Q: What is the main difference between an AT and an MT (Mud Terrain) tire?
A: AT tires balance on-road manners with off-road capability. MT tires have huge voids and deep lugs designed mostly for the stickiest mud and rock crawling.
Q: Should I buy tires with white letters facing out or in?
A: This is purely cosmetic. You can choose which side faces out based on which look you prefer for your truck.
Q: Are these tires safe in deep snow?
A: Many quality AT tires carry the “Three-Peak Mountain Snowflake” (3PMSF) symbol. This means they meet specific performance standards for severe snow traction, making them safer than standard all-seasons.
