If you’re eyeing 37-inch tires for your 4x4, you’re serious about capability and stance. From rock gardens to deep mud and long overland miles, we’ve got the right 37s, the tools to confirm fitment, and easy ways to buy and install.
Mud-terrain (M/T): Maximum traction in mud, loose terrain, and technical trails. Built with aggressive lugs, high voids, and reinforced sidewalls for durability when the going gets rough.
All-terrain (A/T): Balanced performance for mixed daily driving and weekend trails. You get confident off-road bite with better on-road comfort, noise, and tread life than most M/Ts.
Tip: Want strong off-road grip but still manageable on pavement? The Yokohama Geolandar M/T G003 is purpose-built for aggressive terrain and is noted for its on-road manners.

Will 37s fit my vehicle?
Many 4x4 trucks and SUVs can run 37s with the right setup. Most applications require a suspension lift and may need trimming, wheel offset changes, and/or re-gearing.
Use one of the options below to confirm fitment. We’re always adding new fitments, and we’ll verify the fit in store.
Fitment tools and guidance:
- Shop by Size: Enter width, aspect ratio, and rim diameter to browse 37s. Shop by size
- Shop by Vehicle: Enter year, make, model, and trim, then view optional sizes for your setup. Shop by vehicle
- Tire Size Calculator: Explore what larger sizes will work best before you buy. Use tire size calculator
Note: While we don’t install lift kits, we work on lifted vehicles every day and have the equipment to get your upgraded tires and wheels mounted and balanced quickly.
How to buy and get installed
1) Choose your size or vehicle in our fitment tools above and add your tires (or a 37-inch tire and wheel package) to cart.
2) At checkout, pick your preferred store and time or select mobile service where available.
3) After ordering, schedule installation. Alignment services are available at many locations and are recommended after suspension changes.
