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:
  • 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)
When 35s make sense:
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
When 37s make sense:
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.
  • 35s = Reliable all-rounder
  • 37s = Built for serious off-road warriors
Which one are you running or planning to run?
