When upgrading your rig, one of the biggest decisions is tire size. 35” and 37” tires are two of the most popular choices – but they each have their own strengths. Here’s a quick breakdown to help you choose the right one:
35” Tires Advantages:
If you daily drive your vehicle, want great trail performance without sacrificing reliability, and don’t want to heavily modify axles, steering, or brakes – 35s are the sweet spot.
37” Tires Advantages:
If your rig is heavily modified (gearing, axles, suspension upgrades) and you’re serious about hardcore wheeling — 37s give you a real advantage. But expect more strain, more maintenance, and a slight hit to MPG.
Quick Tip:
If you plan to jump to 37s, don’t forget about supporting mods: re-gearing, reinforced axles, upgraded brakes, steering stabilizers, and body clearance mods are often needed.
Final Thought:
There’s no wrong answer — it all depends on your driving style, budget, and goals for the build.

35” Tires Advantages:
- Less stress on drivetrain, suspension, and steering components
- Better fuel economy compared to 37s
- Easier to regear (or sometimes even optional)
- Great off-road capability without needing major vehicle mods
- Cheaper cost (both tire price and long-term wear)
If you daily drive your vehicle, want great trail performance without sacrificing reliability, and don’t want to heavily modify axles, steering, or brakes – 35s are the sweet spot.
37” Tires Advantages:
- Increased ground clearance for more aggressive trails
- Larger footprint = better traction in sand, rocks, and mud
- Look way more aggressive (if that matters to you!)
- Higher breakover angles for technical off-roading
If your rig is heavily modified (gearing, axles, suspension upgrades) and you’re serious about hardcore wheeling — 37s give you a real advantage. But expect more strain, more maintenance, and a slight hit to MPG.

If you plan to jump to 37s, don’t forget about supporting mods: re-gearing, reinforced axles, upgraded brakes, steering stabilizers, and body clearance mods are often needed.

- 35s = Reliable all-rounder
- 37s = Built for serious off-road warriors
