33" Tires:

Not long ago, installing a set of 33s used to be a major accomplishment for CJ, YJ, and TJ owners. Nowadays, they're the standard for JL Rubicon models, and with just a few tweaks, you can run 33s on your JL Sport too.

They might seem modest compared to the big boys out there, but don't underestimate the power of 33-inch tires. Pair them with some smart line choices and a capable driver and you can conquer some serious terrain.


  • Lighter weight, which can lead to better fuel efficiency and less strain on suspension components.
  • More affordable compared to larger sizes.
  • Maintains stock-like handling and acceleration characteristics.
  • Suitable for light off-roading and daily driving.


  • Limited ground clearance compared to larger sizes, which may restrict off-road capabilities.
  • Less traction and stability on challenging terrain compared to larger tires.


35" Tires:

In the JK Wrangler era, 35s were like the holy grail for those weekend warriors hitting the trails. They gave you an aggressive look without sacrificing your comfort on the highway, and off-road, they struck a great balance between capability and reliability.

In the JL world, 35s are often the gateway into big tire territory for many Jeepers. They up your game in terms of both capability and style, all while keeping the mod list relatively short and affordable. If you're itching to get some bigger tires without diving headfirst into a sea of mods, 35s might just be your perfect match.


  • Improved ground clearance and capability over stock tires.
  • Enhanced traction and stability on rough terrain.
  • Suitable for moderate off-roading without significant sacrifices in on-road performance.


  • Increased weight compared to 33" tires, potentially affecting fuel efficiency and acceleration.
  • May require modifications such as suspension upgrades, re-gearing or trimming for optimal performance.
  • Can cause slight changes in handling and braking due to the larger size.


37" Tires:

Alright, now we're getting into the big leagues. Back in the TJ Wrangler days, running 37s was a significant undertaking. It required a whole lot of elbow grease and tinkering to get things just right.

Fast forward to today's JL Wranglers, running 37s is far more simple. Thanks to their beefed-up build and larger dimensions, JLs have made it a whole lot easier to run 37s safely. So, if you're eyeing a set of 37s for your Wrangler, rest assured – it's not as daunting a task as it once was.


  • Significant increase in ground clearance and off-road capability.
  • Excellent traction and stability on challenging terrain.
  • Suitable for serious off-roaders while still maintaining solid highway driving characteristics.


  • Substantial weight increase, which can negatively impact fuel efficiency, acceleration, and braking.
  • For 37s, a suspension lift will be necessary in most applications, and this is where the more serious off-roaders will want to look into steering and drivetrain upgrades.
  • Higher cost compared to smaller sizes.


38" Tires:
























When it comes to tire sizes for JL Wranglers, 38s often hit that sweet spot – not too big, not too small, just right. Put on a set of 38s, and your Jeep will be a beast off-road, yet still cruise down the highway comfortably, especially if you've got the longer wheelbase of a 4-door Wrangler or Gladiator. Plus they look darn good too if you ask us.


  • Excellent off-road capability with exceptional ground clearance.
  • Considered to have very proportional looks on JL Wranglers.
  • Still comfortable on a daily driver by Jeep standards.


  • Significant weight increase, leading to reduced fuel efficiency and acceleration.
  • Suspension upgrades will be mandatory to run 38s effectively while steering and drivetrain upgrades are highly recommended. Re-gearing will also likely be necessary.
  • Limited availability and higher cost compared to smaller sizes.

40" Tires:





















Some like to call them: "the new 37s." With Wranglers getting bigger and more capable, 40s are all the rage these days. What used to be reserved for the most hard-core of off-roaders is now becoming a regular sight on everyday rigs.

Running 40s might mean sacrificing a bit of your on-road handling characteristics, but for some, it's a trade-off they're more than willing to make to run some big ol’ tires.


  • Ultimate off-road capability and ground clearance.
  • Superior traction and stability in the most extreme conditions.
  • They’re big ol’ 40-inch tires.


  • Substantial weight increase, having a significant impact on fuel efficiency, acceleration, and braking.
  • Extensive modifications and upgrades necessary, including lift kits, re-gearing, steering, drivetrain, and brakes.
  • Limited availability and significantly higher cost compared to smaller sizes.
  • Your friends will kick your tires and say: “Man those are some big ol’ tires.”

Final Thoughts

To wrap things up, finding the perfect tire size for your JL Wrangler boils down to your unique needs, style preferences, and, of course, your wallet. Want to go big with larger tires? Keep in mind considerations like weight, fuel efficiency, intended use, and the need for additional mods.

Before you pull the trigger, take a second to think about how you'll be using your Wrangler.
