Why Upgrade Your Tires and Suspension?

Upgrading the tires and suspension on your Jeep XJ Cherokee is one of the most effective ways to transform its capability, comfort, and safety. The XJ’s stock components were designed for a blend of on-road civility and light off-road use, but as you push the vehicle harder on trails or tackle rougher terrain, limitations become obvious. A properly matched tire and suspension setup delivers four key benefits:

  • Improved Traction: All-terrain or mud-terrain tires with deeper tread blocks, stronger sidewalls, and specialized rubber compounds grip loose gravel, rock, mud, and snow far better than worn or highway-focused tires.
  • Enhanced Ride Quality: Upgraded shocks, coils, and leaf springs absorb impacts from ruts, roots, and washboard roads more effectively, reducing fatigue and improving control.
  • Increased Ground Clearance: Lift kits raise the chassis, allowing you to clear larger obstacles and reducing the risk of undercarriage damage on uneven trails.
  • Better Handling and Stability: A well-engineered suspension kit improves steering response, reduces body roll, and keeps the tires planted through corners and over off-camber sections.

When you combine upgraded tires with a suspension lift, the Jeep XJ becomes significantly more capable off-road while often improving on-road manners when properly aligned and matched.

Choosing the Best Tires for Your Jeep XJ Cherokee

Selecting the right tires depends on your typical driving environment. For most XJ owners who mix daily driving with weekend trail runs, an all-terrain tire is the sweet spot. However, if you frequently encounter deep mud or rock crawl, a more aggressive mud-terrain tire may be worth the trade-off in road noise and rolling resistance. Below are four of the most proven options for the XJ.

BFGoodrich All-Terrain T/A KO2

The BFGoodrich All-Terrain T/A KO2 has become a benchmark in the off-road community thanks to its legendary durability and balanced performance. It features a three-ply sidewall construction that resists punctures from sharp rocks and sticks, while the tread pattern includes interlocking tread blocks for solid traction in loose dirt and snow. Many XJ owners run KO2s in 31×10.50R15 or 33×10.50R15 sizes with a 3- to 4-inch lift. The tire is also Severe Snow Rated, making it legal for winter driving in many states. One minor drawback is its weight, which can slightly reduce acceleration and fuel economy, but the trade-off in longevity and toughness is hard to beat. Check out the BFGoodrich KO2 on their official site.

Goodyear Wrangler Duratrac

The Goodyear Wrangler Duratrac is a favorite among XJ owners who face snow, mud, and rocky trails in equal measure. Its aggressive, self-cleaning tread pattern features large shoulder blocks and deep siping that bite into snow and slush. The Duratrac uses a unique Tractive Groove Technology that helps evacuate mud and debris, maintaining grip in messy conditions. It’s available in many common XJ sizes, including 30×9.50R15 and 31×10.50R15. On the highway, the Duratrac produces slightly more noise than the KO2, but it’s still tolerable for daily use. For those who live in regions with harsh winters, this tire is an excellent compromise between a dedicated winter tire and an all-season all-terrain.

General Grabber AT2

For budget-conscious XJ owners who don’t want to sacrifice capability, the General Grabber AT2 delivers impressive performance at a lower price point. It combines an all-terrain tread pattern with reinforced sidewalls and a robust construction that resists cuts and chips. The Grabber AT2 has a symmetrical tread design that wears evenly and remains quiet on pavement, making it a great choice for a daily-driven Jeep that sees regular off-road use. Off-road, it offers reliable traction on gravel, dirt, and moderate mud, though it will struggle in deep slop compared to a dedicated mud tire. Many owners report exceptional tread life, often exceeding 50,000 miles with proper rotation and alignment.

Cooper Discoverer STT Pro

The Cooper Discoverer STT Pro is an extreme mud-terrain tire built for hardcore trail use. Its massive, open shoulder lugs and full-depth three-ply sidewalls provide unmatched bite in rocks and deep mud. The STT Pro uses an Armor Tek3 construction that minimizes carcass damage, while the specially formulated tread compound remains flexible in cold conditions. This tire is significantly louder on pavement than all-terrain options, and it will reduce highway fuel economy, but for dedicated off-roaders who tackle serious obstacles, it’s one of the most capable options available. Common sizes for the XJ include 33×12.50R15 and 35×12.50R15, which require at least 4.5 to 6 inches of lift and careful wheel offset selection to avoid rubbing.

Top Suspension Upgrades for Jeep XJ Cherokee

Upgrading the suspension involves more than just achieving the desired lift height. The best kits include matched springs, shocks, and control arms that maintain proper geometry, articulation, and ride quality. Here are four highly regarded options for the Jeep XJ Cherokee.

Rusty’s Off-Road 3-Inch Lift Kit

Rusty’s Off-Road is a well-known name in the Jeep community, and their 3-inch lift kit strikes a balance between affordability and capability for XJ owners. The kit typically includes new front coil springs (with a choice of spring rates for different bumper/winch setups), rear add-a-leaf or full leaf packs, and Rusty’s own monotube shocks. It delivers enough clearance for 31-inch tires and moderate off-road use without drastically altering ride quality. Many owners pair this kit with Rusty’s adjustable track bar and sway bar disconnects to fine-tune suspension geometry and increase front articulation. Installation is straightforward for a DIY mechanic, and the kit is backed by a solid warranty.

Skyjacker 4-Inch Lift Kit

Skyjacker has been building suspension lifts for decades, and their 4-inch Softride kit is a popular choice for XJ owners who want more aggressive clearance for 32-inch or 33-inch tires. The kit features Softride coil springs that are designed to provide a smoother ride than stiffer budget options, along with Nitro 8000 series shocks. For the rear, Skyjacker includes either add-a-leaf or full leaf springs, depending on the version. A key advantage of Skyjacker’s XJ kit is that it includes pitman arm drop and often a transfer case drop kit to reduce driveline vibration. While not as fine-tuned as premium brands like OME, Skyjacker offers good value and proven durability for weekend trail rigs.

Old Man Emu (OME) Suspension Kit

Old Man Emu, manufactured by ARB, is widely regarded as one of the best suspension upgrades for the XJ. Designed to handle the weight of bumpers, winches, and rooftop tents, OME coils and leaf springs are load-rated and available in multiple options (medium vs. heavy duty). The Nitrocharger shocks are gas-charged and valved specifically for the XJ’s weight, providing a controlled, compliant ride on pavement and excellent damping off-road. The typical OME lift for an XJ is around 1.5 to 2 inches, which is perfect for fitting 30-inch or 31-inch tires without the need for major drivetrain modifications. OME kits maintain near-stock geometry, so they don’t require track bar relocations or slip yoke eliminators—ideal for daily drivers. Learn more about Old Man Emu suspension systems.

Teraflex 2.5-Inch Lift Kit

Teraflex has built a reputation for precision engineering, and their 2.5-inch lift kit for the XJ Cherokee offers a moderate height increase with minimal compromises. The kit includes progressive-rate coil springs that reduce harshness over small bumps, along with Teraflex’s Nitro shocks or optional Fox shocks for a custom feel. For the rear, Teraflex uses a full replacement leaf pack with military wrap for improved durability and a more linear spring rate. One standout feature is the inclusion of extended sway bar links and a rear sway bar drop bracket to maintain roll control. This lift is an excellent choice for owners who want to run 30- or 31-inch tires while retaining factory-like ride and handling. It also pairs well with aftermarket bumpers and recovery gear without sagging.

Installation and Maintenance Considerations

Installing new tires and suspension components on your Jeep XJ can be a rewarding DIY project, but it requires careful planning, proper tools, and attention to detail. Below are essential steps and ongoing maintenance tips to ensure your upgrades perform safely.

Pre-Installation Checklist

  • Gather the Right Tools: A quality floor jack, jack stands (rated for at least 3 tons), a torque wrench, socket set (metric and standard), penetrating oil, and spring compressors are essential.
  • Read the Instructions: Every lift kit comes with detailed instructions. Follow them step by step, noting torque specs and sequencing for bolts.
  • Check Tire and Wheel Compatibility: Ensure your chosen tires fit the lift height and that wheels have proper backspacing and offset to avoid rubbing on control arms or leaf springs at full turn.
  • Address Driveline Angles: Lifts over 3 inches often require a slip yoke eliminator (SYE) and a new driveshaft to eliminate vibrations. For smaller lifts, a transfer case drop may work, but it reduces ground clearance.

Post-Installation Alignment and Adjustments

  • Wheel Alignment: After any suspension lift, take your XJ to a shop that can align the front end. Adjust camber, caster, and toe to factory or slightly modified specs (more caster improves highway stability).
  • Track Bar Relocation: A raised track bar bracket or adjustable track bar centers the axle under the vehicle. Misalignment can cause the steering wheel to be off-center and uneven tire wear.
  • Brake Line Extensions: With lifts over 3 inches, factor in replacement or relocation brackets for the braided brake lines to prevent stretching or pinching at full droop.
  • Bump Stop Tuning: Ensure the bump stops are tall enough to prevent the tires from contacting the fenders or frame at full compression. Polyurethane spacers are easy to install.

Ongoing Maintenance

  • Rotate Tires Every 5,000 Miles: Aggressive tires wear faster if not rotated regularly. Use a 5-tire rotation pattern if you have a matching spare.
  • Inspect Suspension Components: Check shock bushings, spring isolators, and control arm bolts for looseness or deterioration every oil change. Re-torque after the first 500 miles of driving.
  • Monitor Driveline U-Joints: Lifted XJs put extra angular stress on driveshaft U-joints. Listen for clicking sounds and grease them if they have grease fittings.
  • Check Tire Pressure: Off-road tires often require different pressures for pavement vs. trail. Maintain recommended pressure around 30-35 psi on the road and lower (15-20 psi) for rock crawling, but always air back up before highway driving.
