Prepare
1. Remove wheel. See Front wheel or Rear wheel.
2. Check wheels for lateral and radial runout. See Wheel runout.
Remove
Note: Take care when replacing tire to prevent cosmetic damage to wheel.
1. Deflate tire.
2. Loosen both tire beads from rim flange.
3. Remove tire.
Install
Warning: Match tires, tubes, rim strips or seals, air valves and caps to the correct wheel. Contact a Harley-Davidson dealer. Mismatching can lead to tire damage, allow tire slippage on the wheel or cause tire failure, which could result in death or serious injury.
Warning: Use only Harley-Davidson specified tires. See a Harley-Davidson dealer. Using non-specified tires can adversely affect stability, handling or braking, which could result in death or serious injury.
Warning: Harley-Davidson front and rear tires are not the same. Interchanging front and rear tires can cause tire failure, which could result in death or serious injury.
Warning: Do not exceed manufacturer's recommended pressure to seat beads. Exceeding recommended bead seat pressure can cause tire rim assembly to burst, which could result in death or serious injury.
Warning: Be sure tires are properly inflated, balanced, undamaged, and have adequate tread. Inspect your tires regularly and see a Harley-Davidson dealer for replacements. Riding with excessively worn, unbalanced, improperly inflated, overloaded or damaged tires can lead to tire failure and adversely affect stability and handling, which could result in death or serious injury. Only install original equipment tire valves and valve caps. A valve, or valve and cap combination, that is too long or too heavy can strike adjacent components and damage the valve, causing rapid tire deflation. Rapid tire deflation can cause loss of vehicle control, which could result in death or serious injury.
Notes:
- Mount tires with arrows molded into the tire sidewall with the arrow pointing in the direction of forward rotation.
- If a tire has a colored balance dot on the sidewall, locate the balance dot next to the valve stem.
1. Install tire.
2. Inflate tire. For tire pressures, see Inspect tires.
3. Balance tire.
Clean and inspect
General
Warning: Replace punctured or damaged tires. In some cases, small punctures in the tread area may be repaired from within the removed tire by a Harley-Davidson dealer. Speed should NOT exceed 50 mph (80 km/h) for the first 24 hours after repair, and the repaired tire should NEVER be used over 80 mph (130 km/h). Failure to follow this warning could lead to tire failure and result in death or serious injury.
1. Clean the inside of tire.
2. Clean rim as necessary.
3. Inspect the tire for wear and damage.
4. Inspect tread depth, see Inspect tires, Replace.
5. Replace as necessary.
Tire Runout
Note: Avoid measuring tire runout on raised letters or vents.
1. Check tire pressure. See Inspect tires, Replace.
2. Check lateral tire runout.
- a. Mount the wheel and tire in a wheel stand.
- b. See Figure 3-21. Spin the wheel and measure tire lateral runout from a fixed point to a smooth area on the tire sidewall.
- c. Compare reading to specifications. Refer to Table 3-4.
- d. If tire runout exceeds specification, remove tire and check wheel lateral runout. See Wheel runout. If wheel is within specification, replace tire.
3. Check radial tire runout.
- a. Mount the wheel and tire in a wheel stand.
- b. See Figure 3-22. Spin the wheel and measure tire radial runout at the tread centerline.
- c. Compare reading to specifications. Refer to Table 3-4.
- d. If tire runout exceeds specification, remove tire and check wheel radial runout. See Wheel runout. If wheel is within specification, replace tire.

Balance
Static vs Dynamic
Wheel balancing is recommended to improve handling. Balancing wheels reduces vibration especially at high speeds.
Static balancing will produce satisfactory results for normal highway speeds. Dynamic balancing can produce better results for deceleration.
Weights
The maximum weight permissible to accomplish balance is 99.2 g (3.5 oz) (total weight applied to the rim). If more than 99.2 g (3.5 oz) of weight is required, rotate the tire 180 degrees on the rim and again balance the assembly. Balance wheels to within 14 g (0.5 oz).
All wheel weights currently supplied by Harley-Davidson are made from zinc which is lighter than lead. The weight of each zinc segment is 5 g (0.18 oz) as compared to 7 g (0.25 oz) for lead. Weights are stamped for easy identification.
Notes:
- If adding more than 43 g(1.5 oz) of weight at one location, divide the amount so that half is applied to each side of rim.
- On cast wheels without a flat area near the bead, place the weights crosswise through the opening.
1. See Figure 3-24. Place weights on a smooth surface of the wheel rim such that centrifugal force will help keep them in place. Make sure the area of application is completely clean, dry, and free of oil and grease.
Note: See Figure 3-23. When installing wheel weights, consider cosmetics. Keep snaking (1) within 1.02 mm (0.040 in) (2) of straight. Also keep the angle alignment of individual segments (3) within 3 degrees.
2. Remove paper backing from the weight. Press firmly in place and hold for ten seconds.
