Our take on the Nitto Mud Grappler 37X13.50R20LT Tires

The Nitto Mud Grappler is a purpose-built mud-terrain light truck tire for lifted trucks, Jeeps and SUVs used in deep mud, loose rock, sand, dirt and snow. In 37x13.50R20LT it carries a 127 load index (3,858 lbs per tire), a Q speed rating (99 mph), load range E and 10 plies, with 21/32 inch of tread and a weight of about 88 lbs. Its blocky lugs run from the tread onto the sidewall for lateral bite in ruts and rocky ground. It trades quiet, smooth road manners for off-road traction, so it suits drivers who spend real time off pavement and accept the noise and wear of an aggressive mud tire.

About the Nitto Mud Grappler 37X13.50R20LT Tires

The Nitto Mud Grappler is a mud-terrain tire for light trucks, Jeeps, and SUVs. It is built for deep mud, loose rock, sand, dirt, and snow. This size is 37x13.50R20LT with a black sidewall.

Large, blocky tread lugs extend from the shoulder onto the sidewall for lateral bite in ruts and on rocks. A high void ratio clears mud and debris from the tread. The symmetrical tread pattern is designed to maximize surface contact.

A high-tensile steel belt package and a damage-resistant rubber compound handle rough, abrasive terrain. The 3-ply polyester sidewall supports aired-down off-road use. The dual sidewall design has a textured "lizard skin" face on one side and a standard look on the other, so either side can face out when mounted.

Questions and answers

Is the Nitto Mud Grappler good for daily driving?
It can be, but it is loud and stiff on pavement and wears faster than an all-terrain. Most owners use it on trucks that spend much of their time off-road.
How does it compare with an all-terrain tire?
It grips better in mud and loose rock and has tougher sidewalls. All-terrain tires are quieter, ride softer, last longer and handle wet pavement better.
What load and speed does this size carry?
The 37x13.50R20LT has a 127 load index, 3,858 lbs per tire, a Q speed rating up to 99 mph, load range E and 10 plies.
Does it fit a 20-inch wheel?
Yes, it is a 37-inch tire for a 20-inch rim, about 37.1 inches tall and 14.1 inches wide overall. A lift is usually needed to clear a 37-inch tire.
Will it fit my truck without a lift?
A 37-inch tire rarely clears stock suspension. Most trucks need a lift or leveling kit and may need trimming or wider wheels.
Is it good in snow?
It moves through deep snow and mud well, but its hard compound and wide voids give less grip on packed snow and ice than a dedicated winter tire.
