NITTO Ridge Grappler A/T Tire (33" - 33x12.50R20)Find parts that fit my vehicle

For Streets and Mountains. Switching back and forth effortlessly from cruising on the highway to driving fast on a soft dirt trail to moderate mudding, the Nitto 33x12.50R20 Ridge Grappler Tire is a heavy-duty hybrid giving your 1987-2024 Wrangler a mix of all-terrain and mud-terrain skills. While this tire can be used on a daily driver – thanks to a special variable pitch pattern that makes it ride smoothly, quietly, and reliably on pavement – it's meant to get out and play in the dirt often, too.

Trail-Ready Features. The shoulder grooves have alternating widths and lengths, encouraging mud to slip out and keep the tire clear for better traction, while the lateral Z-grooves put extra biting edges to work building grip in loose materials. Scoop-like shoulder serrations and rugged sidewall blocks complete the powerful array of high traction features.

Low-Flex Stability. The Nitto Ridge Grappler Tire in its 33x12.50R20 format offers 3,000 lbs maximum load at a maximum pressure of 80 psi, and keeps its strong traction both fully inflated and aired down. The reinforced block foundations, included on the sidewall blocks too, keep the tire stable and greatly reduce flex for better steering response under load. The tires are made tough and have high chip and tear resistance.

Application. Any 1987-2024 Jeep Wrangler, from the YJ, TJ, and JK series, can be equipped with Nitto 33x12.50R20 Ridge Grappler Tires.

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.
