When it comes to building an off-road or overland vehicle, tire size is one of the biggest decisions you will make. It affects everything from appearance and ride quality to capability, reliability, and daily drivability.
Over the years, we have had the opportunity to run a wide variety of tire sizes on different builds, ranging from conservative all-terrain setups to full 37” and 40" off-road packages. Through that experience, one thing has become very clear, there is no universal “best” tire size. The right choice depends entirely on how you use your vehicle and what you value most.
In this blog, we will break down some of the pros and cons of larger versus smaller tire setups to help you decide what works best for your build.
Why Larger Tires Are So Popular
Larger tires, especially 35” and 37” setups, have become increasingly common in the off-road world, and for good reason. Beyond the aggressive appearance, they offer real performance benefits once the pavement ends.
Improved Ride Quality Off-Road
Larger tires typically have taller sidewalls, which help absorb impacts and smooth out rough terrain. On washboard roads, rocky trails, and uneven terrain, bigger tires can dramatically improve comfort and control.
They also roll over obstacles more easily, rather than dropping into every rut or hole in the trail.
Better Ground Clearance
One of the biggest advantages of increasing tire diameter is added clearance beneath the differential. Even a small increase in tire size can help reduce contact with rocks, ruts, snow, and other obstacles.
Increased Traction When Aired Down
Larger tires generally create a bigger contact patch when aired down, helping improve traction in snow, sand, mud, and technical terrain.
With more sidewall and tire volume, drivers can often run lower tire pressures while maintaining confidence and stability off-road.
More Confidence on Technical Terrain
Bigger tires can make difficult terrain feel more manageable. Improved traction and obstacle clearance often allow drivers to approach technical sections more slowly and with greater control.
And of course, there is the appearance factor. Larger tires can completely transform the proportions and stance of a vehicle, which is a huge reason many enthusiasts choose them in the first place.
The Benefits of Smaller or Lighter Tire Setups
While larger tires offer impressive off-road performance, smaller and lighter setups still make a lot of sense for many drivers, especially those who spend more time on pavement.
Better On-Road Performance
Lighter tires generally provide:
- Better fuel economy
- Faster acceleration
- Improved braking performance
- Sharper handling and steering response
- Reduced road noise
For daily-driven vehicles, these factors can make a significant difference.
Reduced Wear and Mechanical Stress
Heavier tires place additional strain on components like:
- Wheel bearings
- Suspension parts
- CV axles
- Steering components
- Brakes
Smaller, lighter tires can help improve long-term reliability and reduce stress on the drivetrain, especially when paired with factory gearing and suspension components.
Easier Fitment
Larger tires often require:
- Suspension modifications
- Body trimming
- Re-gearing
- Aftermarket wheels
- Brake upgrades
Smaller tires are typically easier to fit while maintaining factory-like drivability and comfort.
So, What Tire Size Is Right for You?
The best tire size ultimately depends on how you use your vehicle.
If your build spends most of its time on pavement, commuting, road trips, or light trail use, a smaller and lighter setup may provide the best balance of comfort, reliability, and efficiency.
If you regularly explore rough terrain, deep snow, technical trails, or remote backroads, a larger tire may provide noticeable improvements in capability and confidence.
And realistically, appearance matters too. Many enthusiasts want a setup that performs well but also makes them look back at their vehicle after parking it.
There is nothing wrong with building a vehicle that reflects both your functional needs and your personal style.
Final Thoughts
Tires are one of the most impactful upgrades you can make to an off-road vehicle. The right setup can completely change how your vehicle looks, drives, and performs both on and off the trail.
Whether you prefer a practical all-terrain setup or a full 37” off-road build, the goal is to choose a tire that matches your driving style, terrain, and long-term goals for the vehicle.
Over the years, we have had the opportunity to test and run a wide variety of all-terrain and mud-terrain tires across many different builds and conditions. Through that experience, we continue to be big supporters of Yokohama Tires and have had consistently great experiences with their off-road tire lineup both on and off the trail.
