Specs. Nitto's Trail Grappler mud terrain tire is a hybrid between Nitto's Mud Grappler and their Terra Grappler. This tire balances aggressive off-road performance with comfort and road noise. This tire is a 285/70R17 and fits 7.5 to 9.5 inch wide rims. In comparison to its Mud Grappler cousin, the Trail Grappler is 36 percent quieter on the highway. The 3 ply, high turn up, polyester sidewalls reduces the risk of punctures. Nitto balances tread blocks with voids to enhance both off-road performance and on-road comfort. The Z style grooves provide lateral stability and greater mud traction. The voids and the chiseled shoulders also help to keep mud and rocks from sticking in the tire. Nitto backs this tire with a 60 month warranty.

Application. Fits 1987 - 2025 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.
