      Specs. These Nitto Trail Grapplers are a massive: sized 37x12.5R17 and allowing 8.5 to 11 inch wide rims to fit, you'll have the perfect set of wheels to go along with a massive lift. The 3 ply high turn up polyester sidewalls plus thick rubber layer make these tires resistant to punctures. The tread surface features Z style grooves for lateral stability and for traction in the mud. The tapered grooves give this tire added bite into the earth for excellent off-road capabilities. Although this tire is centered around mudding, Nitto's engineers added characteristics so your Jeep retains its highway comfort and quietness. The gaps in the tread are balanced for reduced road noise without compromising off-road performance. The sipes within the tread blocks increases wet weather traction. The shoulder groves are an all-season design to retain off-road stiffness. Nitto backs this tire with a 60 month warranty.

      Application. Fits 1987 - 2024 YJ, TJ and JK Wranglers.

      What is the best gear ratio to run for larger tires? When you increase the diameter of your tires, your vehicle's engine has to work harder to turn them. Naturally, this will lead to increased fuel consumption and reduced performance. So, when upgrading to a set of larger tires you should re-gear your rig to regain this lost acceleration, performance and fuel economy.

      Find your original tire size and gear ratio using the chart listed below, the intersection should be your approximate RPMs at 65 MPH. Then find your new tire size and follow it across to the closest RPM to your original tires, this will be your gear ratio choice.

      This chart is based on driving at 65 MPH with a 1:1 gear ratio and a manual transmission in 4th gear. Please note if your vehicle is equipped with an automatic transmission your RPMs will be higher due to normal transmission and the torque converter slippage. In overdrive your RPMs will be approximately 15% to 30% less than indicated.
