Larger Tires Guide for Club Car Speed

Boost Speed with Larger Tires

Want to push your Club Car Precedent or Tempo golf cart past 19.6 MPH? Upgrading to larger tires can amplify your speed when paired with Speed Code 4. Here’s how it works:

• How It Works: Larger diameter tires increase the distance covered per wheel rotation, effectively raising top speed without changing motor RPM.
• Example: Stock 18-inch tires vs. 20-inch tires = ~10-15% speed gain (e.g., 19.6 MPH to 21-22 MPH).
• Trade-Off: Slight torque loss on hills—best for flat courses.

Choosing the Right Tire Size

Selecting the correct tire size for your Club Car is crucial for optimal performance:

• 20-Inch Tires: A popular choice for a balanced speed increase (e.g., 21 MPH with Speed Code 4). Suitable for most Precedent and Tempo models without modifications.
• 22-Inch Tires: For maximum speed (e.g., 22 MPH), but may require a lift kit to ensure axle clearance—typically a 2-3 inch lift kit, costing $100-$200.
• Check Clearance: Measure the space between your current tires and the fender (at least 1-2 inches of clearance is needed to avoid rubbing).
• Tire Type: All-terrain tires are recommended for durability and grip, especially if you drive on mixed surfaces like grass, gravel, or pavement.

Tip: If you’re unsure about clearance, consult a golf cart dealer—they can recommend the best tire size for your specific model.

How to Install Larger Tires

Installing larger tires on your Club Car is straightforward but requires some mechanical work:

• Step 1: Gather Tools: You’ll need a jack, jack stands, a socket wrench (usually 3/4-inch), and a torque wrench.
• Step 2: Lift the Cart: Jack up your Club Car at each corner (one at a time) and secure with jack stands.
• Step 3: Remove Stock Tires: Use the socket wrench to remove the lug nuts and take off the stock tires.
• Step 4: Install New Tires: Mount the larger tires onto the wheels, ensuring they’re properly seated. If you’re using new wheels, ensure they match your cart’s bolt pattern (usually 4x4).
• Step 5: Tighten Lug Nuts: Hand-tighten the lug nuts, lower the cart, and use a torque wrench to tighten to 50 ft-lbs in a star pattern.
• Step 6: Test Drive: Test the cart on a flat surface to ensure the tires don’t rub and the speed has increased as expected.

Note: If you installed a lift kit for larger tires, double-check the alignment and suspension adjustments to ensure a smooth ride.

Additional Tips for Larger Tires

Maximize the benefits of larger tires with these tips:

• Adjust Tire Pressure: Larger tires typically require 18-22 PSI—check the tire sidewall for the recommended pressure to ensure optimal performance and prevent uneven wear.
• Monitor Speed Gains: Use a GPS app or speedometer to measure your new top speed after installation. If the increase is less than expected, check for other limiting factors like battery health or motor condition.
• Balance Speed and Stability: Larger tires can raise your cart’s center of gravity, increasing the risk of tipping on sharp turns. Drive cautiously, especially on uneven terrain.
• Upgrade Brakes if Needed: Higher speeds may require better braking power—consider upgrading to high-performance brake pads if you notice longer stopping distances.

Long-Term Maintenance for Larger Tires

Larger tires can affect your Club Car’s performance over time. Here’s how to maintain them:

• Regular Inspections: Check for uneven wear every 3-6 months—larger tires may wear faster due to increased speed and load. Rotate tires if wear patterns emerge.
• Alignment Checks: Larger tires can throw off your cart’s alignment, especially if a lift kit was installed. Have a professional check alignment annually to prevent steering issues.
• Suspension Upgrades: If you notice a rougher ride, consider upgrading to heavy-duty shocks (around $50-$100) to handle the increased tire size.
• Monitor Battery Range: Larger tires can slightly reduce your range per charge due to increased rolling resistance—plan your trips accordingly.

Tip: Keep a log of your tire maintenance schedule to ensure consistent performance and longevity.
