My Buying Guide on ’37X13.50R20 Nitto Mud Grappler’

Before purchasing a set of ’37X13.50R20 Nitto Mud Grappler’ tires, there are a few important factors that you should consider. As an experienced off-road enthusiast, I have personally used these tires and can provide a first-hand review of their performance and durability. In this buying guide, I will cover the essential information that you need to know before investing in these tires.

Size and Fitment

The ’37X13.50R20 Nitto Mud Grappler’ is a popular size for lifted trucks and SUVs. The first number (37) indicates the overall tire diameter in inches, while the second number (13.50) represents the width of the tire in inches. The “R” stands for “Radial” and the last number (20) is the rim diameter in inches.

It is important to note that these tires are designed for vehicles with at least a 6-inch lift kit, as they are quite large and may cause rubbing if installed on a vehicle with a smaller lift or no lift at all.

Tread Design

The Nitto Mud Grappler features an aggressive tread pattern with large, chunky lugs that provide excellent traction in mud, sand, and other off-road terrains. The sidewalls also feature deep shoulder lugs for added grip in challenging situations.

I have found that these tires perform exceptionally well in both wet and dry conditions on paved roads as well. However, due to their deep treads, they may produce some road noise which can be easily overlooked by the impressive off-road performance.

Durability

One of the standout features of the ’37X13.50R20 Nitto Mud Grappler’ is its exceptional durability. The 3-ply sidewall construction provides excellent puncture resistance while also increasing load-carrying capacity.

I have put these tires through some harsh conditions and they have held up remarkably well without any signs of wear or tear. However, it is important to rotate them regularly to ensure even wear and prolong their lifespan.

Price

The price for a set of four ’37X13.50R20 Nitto Mud Grapplers’ can range from $1,400 to $1,800 depending on where you purchase them from. While they may seem expensive compared to other off-road tires on the market, their performance and durability make them worth every penny.

Conclusion

In my personal experience, I highly recommend the ’37X13.50R20 Nitto Mud Grappler’ for any off-road enthusiasts looking for a reliable and high-performing tire. With its aggressive tread design, exceptional durability, and impressive performance on both paved roads and off-road terrains, it is definitely worth considering as your next tire upgrade.
