Tire Mount and Balance

Remove wheels from vehicle, dismount old tires from wheels, mount new tires onto wheels, balance tire and wheel assemblies, and reinstall wheels on vehicle.

Warnings

Tools required

Parts

• Tires (set of 4) × 4 — 215/50R17 or as specified on door placard
• Valve stems (TPMS compatible) × 4 — Use OEM specification for TPMS sensor compatibility
• Wheel weights (clip-on or adhesive) × 1 — As needed per wheel balance

Preparation

1. Park vehicle on level surface and engage parking brake
2. Loosen all wheel lug nuts approximately one full turn while vehicle is on ground
3. Raise vehicle using floor jack at designated lift points and support securely on all four jack stands
4. Remove all four wheels from vehicle and mark each wheel with its position (LF, RF, LR, RR) if reusing wheels

Procedure

1. 1

   Deflate and inspect existing tires
   Remove valve caps from all four wheels. Use valve core tool to remove valve cores and fully deflate existing tires. Inspect wheels for damage, cracks, or bends that would prevent proper tire mounting. Check TPMS sensor condition through valve stem opening with flashlight.
2. 2

   Remove old tires from wheels
   Place first wheel on tire changer machine. Break both upper and lower beads using tire changer bead breaker, working around circumference. Position TPMS sensor at 12 o'clock position away from dismount head to minimize damage risk. Use tire changer arm to dismount tire from wheel, exercising caution around TPMS sensor location. Remove old tire and set aside. Repeat for all four wheels.
3. 3

   Clean wheels and inspect TPMS sensors
   Clean wheel bead seating surfaces thoroughly, removing all old weights, dirt, and corrosion. Inspect TPMS sensors for damage. Verify sensor nuts are tight (hand tight plus 1/4 turn). If installing new valve stems, ensure they are TPMS-compatible metal valve stems, not rubber stems which can fail with TPMS sensor weight.
4. 4

   Mount new tires onto wheels
   Check new tire directional arrows and inside/outside markings for proper orientation. Apply tire bead lubricant to both wheel beads and tire beads. Position TPMS sensor at 12 o'clock and align tire on wheel with proper rotation direction. Use tire changer to mount lower bead first, then upper bead, keeping mount head away from TPMS sensor location. Verify tire is properly seated in rim drop center. Repeat for all four tires.
5. 5

   Inflate and seat tire beads
   Install valve cores into all wheels. Inflate each tire to approximately 40 PSI to seat beads, watching for even bead seating around both sides of rim. You may hear popping sounds as beads seat properly. Once beads are fully seated, adjust pressure to 38 PSI cold or as specified on door placard. Inspect for any air leaks around bead and valve stem.
6. 6

   Balance tire and wheel assemblies
   Mount first tire and wheel assembly on wheel balancer machine. Enter wheel diameter and width parameters specific to Bolt EUV 17-inch wheels. Spin wheel and allow balancer to determine heavy spots. Install wheel weights as indicated by balancer readout, using clip-on weights on inner barrel or adhesive weights on outer rim as appropriate for wheel style. Re-spin to verify balance is within acceptable limits (typically under 0.25 oz). Repeat balancing process for all four wheels.
7. 7

   Reinstall wheels on vehicle
   Clean wheel hub mounting surfaces and brake rotor hats to remove any rust or debris. Install wheels onto vehicle in their original positions if rotating, or according to rotation pattern if applicable. Hand thread all five lug nuts onto each wheel to prevent cross-threading. Snug lug nuts in star pattern by hand.

8. 8

   Torque lug nuts to specification
   Using calibrated torque wrench, torque all lug nuts to 190 Nm (140 lb-ft) in proper star pattern sequence: start at top position, then move to opposite bottom, then opposite sides, completing the star. Make at least two complete star pattern passes to ensure even torque distribution and proper wheel seating. Verify each lug nut reaches specified torque.

   Lower vehicle and perform final torque check
   Carefully raise vehicle slightly with floor jack and remove all four jack stands. Lower vehicle completely to ground. Perform final torque check on all lug nuts in star pattern at 190 Nm (140 lb-ft) with vehicle weight on wheels. This ensures proper torque with suspension loaded.

    Reset TPMS and verify operation
    Start vehicle and verify TPMS warning light illuminates briefly then extinguishes. Drive vehicle at speeds above 25 mph for at least 2 minutes to allow TPMS sensors to transmit data to vehicle computer. TPMS system should auto-relearn sensor positions. If TPMS light remains on, use factory scan tool to manually initiate TPMS relearn procedure according to GM specifications.

Reassembly

1. Install valve stem caps on all four wheels to protect valve cores from debris
2. Record tire pressures and verify they match door placard specifications
3. If tires are directional or asymmetric, verify proper installation orientation on vehicle

Verification

• Verify all lug nuts are torqued to 190 Nm (140 lb-ft) in star pattern with vehicle on ground
• Confirm tire pressures are set to 38 PSI cold or as specified on driver door placard
• Test drive vehicle at low speed and verify no vibration, pulling, or unusual noise from wheels
• Verify TPMS light is not illuminated on instrument cluster after driving for 2+ minutes above 25 mph
• Perform visual inspection of wheels to ensure no weights are loose and tires appear properly seated
• Re-check lug nut torque after 50-100 miles of driving as best practice
