Tire Mount and Balance

This procedure covers the removal, mounting, balancing, and reinstallation of tires on the 2018-2024 Honda Accord 1.5L Turbo, ensuring proper wheel balance and safe torque specifications.

Warnings

Tools required

Parts

• Tires (set of 4) × 4 — 235/40R19 or as specified on door jamb
• Valve stems × 4 — TR413 or TPMS-compatible valve stems
• Wheel weights (as needed) × 1 — Adhesive or clip-on type
• Valve stem caps × 4 — Standard valve caps

Preparation

1. Park vehicle on level, solid surface and engage parking brake
2. Verify replacement tires match the size specification on the driver door jamb placard
3. Loosen all wheel lug nuts 1/4 turn while wheels are still on the ground
4. Lift vehicle at factory jacking points and support securely on jack stands at all four corners
5. Remove all four wheels and place on clean surface to avoid contaminating tire bead surfaces

Procedure

1. 1

   Remove old tires from wheels
   Deflate each tire completely by removing the valve stem core. Mount the wheel on the tire changing machine and position the bead breaker arm to break both inner and outer beads. Rotate the wheel as needed to break the bead completely around the circumference. Position the mount/demount head and carefully pry the tire off the wheel, ensuring the TPMS sensor (located opposite the valve stem at approximately 180 degrees) is not contacted by the machine head.
   ⚠TPMS sensors are fragile. Keep tire machine head away from the sensor area during demounting to prevent damage.
2. 2

   Inspect wheels and TPMS sensors
   Clean the wheel barrel and bead seat areas thoroughly, removing any corrosion, old weights, or debris. Inspect each wheel for cracks, bends, or damage that would prevent proper tire seating. Check TPMS sensor torque and condition; sensors should be hand-tight plus 1/4 turn (approximately 4-6 Nm). Verify sensor ID matches the vehicle if reusing sensors.
   ℹ️TPMS sensors are programmed to specific wheel positions. Note which sensor came from which wheel position if sensors will be repositioned.
3. 3

   Install new valve stems if needed
   If replacing rubber valve stems (non-TPMS wheels) or TPMS valve stems, install new stems using the appropriate tool. For TPMS valve stems, ensure the O-ring is properly seated and torque the valve nut to manufacturer specification (typically 4-6 Nm). Verify the valve stem is perpendicular to the wheel and not angled.
4. 4

   Mount new tires on wheels
   Apply tire lubricant generously to both tire beads and wheel bead seats. Check tire directional arrows or inside/outside markings and orient correctly. Position the tire on the wheel with the upper bead in the drop center. Position the TPMS sensor at approximately 180 degrees from the valve stem location. Use the tire machine to lever the bottom bead over the wheel rim, then the top bead, keeping the mount head away from the TPMS sensor location throughout the process.
   ⚠Mounting tires without lubricant can damage tire beads and make seating difficult. Use adequate tire lubricant.
5. 5

   Seat tire beads
   Install the valve core and inflate the tire rapidly to seat the beads against the wheel. You should hear audible pops as each bead seats. Do not exceed 40 PSI during seating. Once both beads are seated (verify by inspecting the bead line around the entire circumference), adjust pressure to 35 PSI for balancing.
   ⚠️Never exceed 40 PSI when seating beads. Over-inflation can cause tire or wheel failure resulting in serious injury.
   ⚠If beads do not seat by 40 PSI, deflate completely and reposition the tire. Do not continue inflating.
6. 6

   Balance wheels
   Mount the wheel/tire assembly on the balancer and enter the wheel dimensions (diameter and width) as measured by the balancer arm or calipers. Spin the wheel and allow the balancer to calculate weight placement. Remove any old weights. Install the specified weights at the locations indicated by the balancer (typically both inner and outer positions). Re-spin to verify balance is within 0.25 oz or less. Repeat for all four wheels.
   ℹ️For best results, final balance should show 0.00 oz, though up to 0.25 oz is acceptable for highway use.
7. 7

   Set final tire pressure
   Adjust tire pressure to the specification shown on the driver door jamb placard (typically 32-35 PSI front and rear for the Accord, but verify). Check pressure with an accurate gauge when tires are cold. Install valve stem caps on all four valve stems.
8. 8

   Install wheels on vehicle
   Lift each corner of the vehicle slightly to allow wheel installation. Mount each wheel onto the hub, ensuring the wheel sits flush against the hub face. Install lug nuts by hand, threading each nut 3-4 turns to prevent cross-threading. Lower the vehicle until the tire just contacts the ground but the suspension is not fully loaded.

   Wheel Lug Nuts108 Nm (80 lb-ft)
9. 9

   Torque lug nuts to specification
   Using a calibrated torque wrench, torque all lug nuts to 108 Nm (80 lb-ft) in a star pattern. For the 5-lug Accord pattern: torque one lug, then move to the lug opposite (across the wheel), continuing in a star pattern until all 5 lugs are torqued. Make a second complete pass in the same star pattern to verify all lugs are properly torqued. Repeat for all four wheels.
   ⚠Lug nuts must be torqued in a star pattern to ensure even pressure distribution. Torquing in a circular pattern can warp brake rotors.

    Lower vehicle and perform final checks
    Remove jack stands and lower the vehicle completely to the ground. Perform a final torque check on all lug nuts in the star pattern with the vehicle weight fully on the wheels. Verify all valve caps are installed. If TPMS warning light is illuminated, drive the vehicle 5-10 minutes at speeds above 30 mph to allow the system to relearn sensor positions, or perform manual TPMS relearn procedure using the vehicle settings menu or TPMS tool as required.

Reassembly

1. No disassembly of vehicle components is required for this procedure beyond wheel removal

Verification

• Test drive the vehicle at low speed (15-25 mph) and verify no vibration or pulling is present
• Verify TPMS warning light is not illuminated after 10 minutes of driving above 30 mph
• Re-check lug nut torque after 50-100 miles of driving to ensure they have not loosened
• Verify tire pressures are correct when tires are cold
• Inspect for any air leaks around valve stems or bead seats by listening for hissing or applying soapy water
