What Are 40" Tires' Common Pros and Cons?
There isn't a single "average" tire size on 4x4 vehicles. However, many Jeep models use 31- to 33-inch tires. Equipping 40" tires is a significant upgrade from stock sizes, but it offers several notable benefits. Big tires provide a larger contact patch, which can improve traction and stability off the road. 
Meanwhile, you should consider the extra weight added to your vehicle by bigger tires and wheels. You may need to upgrade your suspension, steering, braking and drivetrain systems to accommodate your larger wheels. Also, remember that some mud tire models are unsuitable for paved surfaces because of their thick thread blocks and large gaps in between. If you plan to drive on paved roads at all, you may want to choose an all-terrain model like the Yokohama GEOLANDAR X-MT. 

Which 40" Tires Are Best?
With 4WP's extensive range of tires, you have many options from which to choose. Our inventory includes 40 inch mud tires like the Mickey Thompson Baja Boss M/T and the Pro Comp Xtreme M/T 2 Radial. Equipped with large tread chunks and wide voids, both the Baja Boss M/T and the Xtreme M/T 2 deliver solid performance on muddy terrain.
