The Jeep CJ, a true icon of American off-road history, has earned its reputation for rugged simplicity and go-anywhere capability. Whether you own a CJ-5, CJ-7, or CJ-8 Scrambler, the right combination of tires and accessories can transform your driving experience—taking you from a capable everyday vehicle to a trail-conquering machine. This guide covers the most impactful upgrades for your CJ, from selecting the perfect tires to must-have accessories that boost performance, safety, and storage. With the right choices, your CJ will remain a reliable and thrilling companion for years to come.

Why Tire Selection Matters for Your Jeep CJ

Tires are the single most important component affecting your CJ’s handling, traction, and overall safety. Unlike modern SUVs with complex electronic assists, the CJ places the responsibility of grip squarely on the driver and the tires. A well-chosen tire can mean the difference between confidently crawling over rocks and getting stuck in mud, or between stable highway cruising and wandering on pavement.

Key Factors to Consider

Tread Pattern

All-terrain tires feature a balanced design with moderate shoulder lugs and siping for wet-road grip. They work well for daily driving with occasional off-road adventures. Mud-terrain tires have aggressive, widely spaced lugs designed to clean out mud and grip loose surfaces, but they can be noisy on pavement and wear faster. For hardcore rock crawling, stickier compounds and specially shaped tread blocks provide maximum traction on slickrock and ledges.

Tire Size

Larger tires increase ground clearance and improve approach and breakover angles, but they also affect gearing, braking, and suspension travel. On a CJ, common upgrades range from 30-inch to 35-inch diameters (or even larger with significant lift). Check your Jeep’s wheel well clearance, axle gearing, and speedometer calibration. Oversized tires without gearing adjustment can rob power and strain drivetrain components.

Terrain Type

Match your tire to your primary driving environment. If you mostly drive gravel roads and dirt trails, an all-terrain tire like the BFGoodrich All-Terrain T/A KO2 provides a good compromise. If you frequent deep mud or rock fields, a dedicated mud-terrain tire such as the Goodyear Wrangler MT/R gives superior self-cleaning and durability. For a mix of sand, snow, and daily driving, consider a tire with winter rating certification (3PMSF).

Durability and Load Rating

CJ owners often load their Jeeps with heavy bumpers, winches, roof racks, and camping gear. Look for tires with reinforced sidewalls (such as BFGoodrich’s CoreGard technology) and higher load index ratings (C, D, or E load range). A stronger sidewall resists punctures and cuts from sharp rocks, and supports heavier loads without excessive flex.

Top Tire Recommendations for Your Jeep CJ

Below are the best tire options available today, each tested and proven on classic Jeeps. Prices vary by size, but all offer excellent value for their intended use.

BFGoodrich All-Terrain T/A KO2

The KO2 is the gold standard for all-terrain tires. Its 3D siping and interlocking tread blocks provide excellent grip in snow and rain, while the sidewall design resists cuts and abrasions. The KO2 is quiet on the highway and lasts longer than many competitors. It’s an ideal choice for CJ owners who want one tire for pavement, gravel, and light trails. Check current sizes and specs on BFGoodrich’s site.

Goodyear Wrangler MT/R with Kevlar

For extreme off-road conditions, the Wrangler MT/R is a top performer. Its Durawall sidewall reinforcement uses Kevlar strands to resist punctures, while the asymmetric tread pattern provides excellent traction in mud, rocks, and dirt. The tire is noticeably louder on pavement than an all-terrain, but its rock-crawling ability is outstanding. Many hardcore CJ owners run these in 33-inch or 35-inch diameters with a 4-inch lift. View product details on Goodyear’s website.

Cooper Discoverer STT Pro

Cooper’s STT Pro is a mud-terrain tire that balances aggressive off-road capability with decent on-road manners. Its Armor-Tek3 carcass construction increases puncture resistance, and the stone ejector ribs prevent rock drilling between tread blocks. The tread design cleans out mud effectively, and the tire wears evenly when properly rotated. It’s a favorite among CJ owners who tackle rocky trails and deep mud but still drive to the trailhead.

General Grabber ATX

The General Grabber ATX is a versatile all-terrain that performs exceptionally well on wet roads and light snow. Its Duragen technology fortifies the tread compound, while the rugged sidewall design protects against cuts. This tire is often chosen by CJ drivers who want a smooth ride for daily commuting but don’t want to hesitate on a muddy two-track. It’s also more affordable than many premium brands without sacrificing quality.

Mickey Thompson Baja Boss M/T

For the CJ owner who demands ultimate off-road traction, the Baja Boss M/T is a modern mud-terrain with PowerPly XL technology for enhanced load carrying. The stepped shoulder lugs and angled tread bars provide excellent bite in loose terrain. Its variable-pitch tread pattern reduces road noise, surprising many drivers for a mud-terrain tire. Available in sizes up to 40 inches, it’s a serious upgrade for heavily modified CJs.

Essential Accessories to Enhance Your Jeep CJ

Beyond tires, the right accessories can dramatically improve your CJ’s off-road capability, safety, storage, and comfort. Here are the most impactful upgrades to consider.

Lift Kits

A lift kit accomplishes two main goals: increased ground clearance for obstacle clearance, and space to fit larger tires. Two primary types exist:

  • Suspension Lift: Replaces springs, shackles, and often adds longer shocks. Provides real wheel travel and maintains suspension geometry. Ideal for serious off-roading. Common lift heights for CJs range from 2.5 inches (to fit 33-inch tires) up to 4-6 inches (for 35-inch and larger tires). Kits from Rough Country, Skyjacker, and Old Man Emu are popular.
  • Body Lift: Uses polyurethane or aluminum pucks placed between the frame and body to raise the body without altering the suspension. Typically 1-2 inches. This allows slightly larger tires but does little for wheel travel. It’s a budget-friendly option when combined with minor fender trimming.

When choosing a lift, consider your CJ’s steering, brake lines, and driveshaft angles. A professional installation is recommended for anything over 2.5 inches.

Skid Plates

Your CJ’s undercarriage—oil pan, transmission, transfer case, and fuel tank—is vulnerable to rocks and stumps. Skid plates made from 3/16-inch or 1/4-inch steel offer robust protection. Aluminum plates are lighter but less durable. Look for full-coverage designs that protect the entire drivetrain. Brands like Poison Spyder, Warn, and JCR Offroad offer bolt-on solutions.

Winches

A winch is essential for self-recovery or helping others. Winch capacity should be at least 1.5 times your Jeep’s weight (a typical CJ-7 weighs around 3,000 pounds; a 4,500- to 6,000-pound winch is a safe range). Two cable types exist:

  • Steel Cable: Durable and abrasion-resistant, but heavy and can be dangerous if it snaps. Less expensive.
  • Synthetic Rope: Lighter, floats, and is safer (less kinetic energy if it breaks). More expensive but easier to handle and kinder to winch hands.

Warn is the industry standard for reliability, with models like the VR Evo and Zeon series. For budget builds, Smittybilt and Superwinch also offer solid options.

Roof Racks and Storage Solutions

Jeep CJs have limited interior space—especially the two-seat CJ-5 and CJ-7. A roof rack adds cargo capacity for camping gear, spare tires, or fuel cans. Look for racks made from aluminum or steel that mount to the roll bar or gutter rails. For heavier loads (like a rooftop tent), reinforce the mounting points and consider a safari-style rack.

Alternatively, a rear tire carrier that swings out on a hinge provides room for a full-sized spare without blocking rear visibility. Brands like Warn, Garvin, and Smittybilt offer bolt-on swing-away carriers designed for CJ models.

Bumpers and Recovery Points

Upgraded front and rear bumpers serve dual purposes: they provide mounting for winches, lights, and D-rings, and they protect the body from trail damage. Look for bumpers made from heavy-gauge steel with integrated recovery points (rated shackle mounts). Popular choices include ARB, Poison Spyder, and Rock Hard 4x4.

Lighting Upgrades

Off-road driving often extends into darkness. Adding a set of LED spot or flood lights can illuminate trails effectively. Install lights on the bumper, above the windshield, or on a light bar. Ensure your CJ’s alternator can handle the extra load—older CJs may need an alternator upgrade to 60 amps or more. H4 LED conversion headlights are another simple upgrade that dramatically improves visibility on pavement.

Interior Comforts

Long trail days demand comfort. Consider replacing worn-out seats with high-back bucket seats for better lumbar support. Installing a lockable center console provides secure storage for phones, tools, and documents. Upgrading the sound system with waterproof speakers and a Bluetooth receiver keeps the music going through open-air driving.

Building the Ultimate Jeep CJ: A Step-by-Step Approach

Rather than buying everything at once, a phased approach helps you align upgrades with your driving style and budget.

Phase One: Safety and Reliability

  • Install a quality winch with a recovery kit (snatch block, tree strap, shackles).
  • Add skid plates protecting the oil pan and transfer case.
  • Upgrade to all-terrain tires in a size that fits your stock suspension.
  • Replace aging suspension bushings and shocks for predictable handling.

Phase Two: Capability

  • Install a 2.5- to 4-inch suspension lift to accommodate 33- to 35-inch tires.
  • Switch to mud-terrain or hybrid tires based on your trails.
  • Add a heavy-duty front bumper with recovery points and winch mount.
  • Add auxiliary lighting for night runs.

Phase Three: Comfort and Storage

  • Install a roof rack or rear tire carrier for camping gear.
  • Upgrade seats and add a center console.
  • Add a lockable storage drawer in the rear footwell (CJ-7) or behind seats (CJ-5).
  • Sound deaden the floor and install weathertight soft top for better daily usability.

Maintaining Your Tires and Accessories for Long Life

Proper maintenance ensures your investments perform when needed and last for years. Here are the essential practices.

Tire Maintenance

  • Check inflation monthly (and before long trips). Off-road driving often requires lower pressures for traction, but always reinflate to pavement pressure before highway driving. Overinflation risks center wear; underinflation causes sidewall flex and heat buildup.
  • Rotate tires every 5,000 to 7,000 miles using a cross-rotation pattern (rear tires move to the front and cross sides). This promotes even wear and extends tread life.
  • Inspect tread depth and damage after every off-road trip. Look for cuts, bulges, or uneven wear that may indicate alignment or balance issues. Replace tires when tread depth approaches 2/32-inch for all-terrains; mud-terrains often lose traction earlier and should be replaced at 4/32-inch for off-road use.
  • Balance tires when installing new ones and after any repair. An unbalanced tire causes vibration and accelerated wear on suspension components.

Accessory Maintenance

  • Winches: Spool out the cable every few months to prevent corrosion and ensure the rope spools evenly. Apply a light lubricant to the drum and free-spool mechanism. For synthetic rope, inspect for fraying and protect with a sleeve.
  • Skid plates: After muddy runs, wash off mud and debris. Inspect for bent or cracked plates, especially around mounting bolts. Torque bolts to spec to avoid rattles.
  • Lift kits: Grease shackle bolts, bushings, and any zerks every oil change. Check for loose fasteners and worn bushings annually. Uneven tire wear or squeaks often indicate worn suspension components.
  • Roof racks: Inspect mounting brackets and crossbars for rust and loose bolts. Clean the rack periodically to prevent grit from scratching the roof. Lubricate locks and hinges.

Final Thoughts

Upgrading your Jeep CJ with the right tires and accessories is one of the most rewarding projects you can undertake as an owner. Each component—whether a set of aggressive mud-terrain tires, a winch that gets you out of a jam, or a roof rack that carries your camping gear—adds a layer of capability and confidence to your driving experience. Start with a clear plan aligned with how you actually use your CJ, invest in quality products, and maintain them diligently. Your CJ is a classic that rewards thoughtful upgrades with decades of reliable service and unforgettable adventures. Whether you’re crawling over rocks in Moab or cruising backroads with the top down, the right setup makes all the difference.
