Excellent Off-Roading Treads and Quiet on the Highway. Get a tire for your Wrangler that is a perfect mix for aggressive off-roading and has functional street use. The NITTO Ridge Grappler is an all-terrain tire that has top-notch treads for off-roading and will give you a smooth, quiet ride on the highway. They perform well under any road condition.

Universal Design. NITTO Ridge Grappler Tires incorporate several unique features such as the dual sidewall design that has an aggressive block design on one side and a traditional sidewall on the other side to select the appearance of your choice. The shoulder grooves and stone ejectors keep the tires clean while providing improved traction for off-road adventures. The variable pitch tread pattern establishes a smooth quiet ride on the highway and facilitates even tread wear.

New Thinking from Nitto. The Ridge Grappler includes a variable pitch tread pattern. This prevents the harmonic resonance associated with highway-speed hum. Shoulder and lateral Z-Grooves help clear mud and improve traction. Alternating tapered edges provide increased bite and traction, especially in aired-down situations.

Works Great and Looks Even Better. The tough, aggressive looks of the Terra Grappler's deep lugs will set your rig apart at the trailhead and in the shopping center parking lot. Choose between two separate sidewall designs, depending on how the Ridge Grappler is mounted. Either way, you'll be riding in style - no matter where the road or trail might take you.

Application. This NITTO Ridge Grappler Tire fits all 1987-2024 Jeep Wrangler models. Please choose your correct size from the options listed above.

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.
