If 35s are bold, 37-inch tires are a statement. They’re massive, aggressive, and instantly transform any truck or SUV into a trail-dominating beast. But as impressive as they look, running 37s isn’t just a cosmetic change—it’s a major step up in performance, capability, and cost.
Before you order that new tire and wheel setup, it’s worth understanding how 37-inch tires affect your truck’s power, handling, and daily drivability.
What You’ll Learn in This Guide
In this article, you’ll learn:
The advantages and drawbacks of upgrading to 37-inch tires.
How they impact clearance, gearing, suspension, and fuel economy.
What supporting modifications are needed to run them safely.
Whether 37s are worth it for your style of driving and off-road goals.
By the end, you’ll know exactly what to expect before making the jump.
1. The Benefits of 37-Inch Tires
The most obvious advantage of 37s is capability. Larger tires increase ground clearance, approach and departure angles, and traction—all crucial for serious off-road performance.
Ground Clearance: 37s can add nearly two inches of extra clearance over 35s, helping you clear rocks, ruts, and obstacles more easily.
Traction: The larger contact patch provides better grip on dirt, sand, and loose terrain.
Aesthetics: 37s give trucks and SUVs a commanding stance that turns heads on and off the trail.
Durability: Most 37-inch tires are built with reinforced sidewalls and aggressive tread patterns designed for heavy-duty use.
For off-roaders tackling rocky terrain, mud, or deep sand, 37s are hard to beat.
2. The Downsides of 37-Inch Tires
The jump from 35s to 37s might seem small on paper, but it comes with real trade-offs—especially if you drive your truck daily.
Reduced Fuel Economy: Larger, heavier tires require more power to turn, cutting MPG significantly.
Slower Acceleration: Unless you re-gear, your truck will feel more sluggish off the line and under load.
Increased Wear: Steering, suspension, and braking components all take on more stress.
Higher Costs: 37-inch tires are more expensive to buy, mount, and balance—and replacement prices add up.
Pro Tip: If you plan to daily drive your truck, the added weight and rolling resistance may outweigh the benefits of going that big.
3. Supporting Mods You’ll Need for 37s
Running 37s safely isn’t as simple as bolting them on. You’ll need supporting upgrades to handle the size and weight properly.
Lift Kit: Minimum of 3–4 inches (5–6 recommended) for proper clearance.
Re-Gearing: Common ratios are 4.56 or 4.88, depending on drivetrain and tire weight.
Trimming / Fender Mods: Larger tires can rub at full lock or under flex—especially on IFS setups.
Upgraded Steering Components: Tie rods, ball joints, and control arms often need reinforcement.
Brakes: Consider upgraded rotors and pads for better stopping power.
If you skip these supporting mods, expect rubbing, sluggish throttle response, and premature wear on drivetrain components.
4. How 37s Affect Ride Quality
Larger tires change how your truck feels on the road.
Ride Comfort: The extra sidewall cushions bumps, improving comfort at low speeds.
Handling: Body roll increases and steering response slows—especially on lifted trucks.
Noise: Aggressive tread patterns hum louder at highway speeds.
37s aren’t unbearable for daily use, but you’ll definitely feel the difference if you’re used to stock tires or smaller all-terrains.
5. Are 37s Right for You?
Ask yourself how you actually use your truck:
| Driving Style | Are 37s Worth It? | Recommended Setup |
|---|---|---|
| Daily Driver | Not Ideal | 33–35” A/Ts for balance and comfort |
| Weekend Off-Roader | Maybe | 35” M/Ts or lightweight 37s with re-gear |
| Dedicated Trail Rig | Absolutely | 37” or 38” M/Ts with lift, gears, and armor |
If your truck spends most of its time off-road or you’re building a show-stopping rig, 37s make sense. For mixed-use vehicles, 35s often provide a better all-around experience.
37-inch tires deliver unbeatable off-road performance and jaw-dropping looks, but they also demand proper setup and commitment. If you’re ready to invest in gears, suspension, and supporting components, 37s can take your build to the next level.
