Tire Balance

Balance all four tires on the 2022 Rivian EDV 500 to eliminate vibration and ensure even tire wear on this electric delivery vehicle.

Warnings

Tools required

Parts

• Adhesive wheel weights × 1 — Use appropriate size for commercial vehicle
• Clip-on wheel weights × 1 — Use appropriate size for wheel type
• Valve cores × 4 — Standard TPMS-compatible

Preparation

1. Park vehicle on level, solid surface and engage parking brake
2. Shift transmission to Park position
3. Verify wheel balancer is properly calibrated per manufacturer specifications
4. Locate tire pressure specification on driver door jamb (typically 60-80 PSI for commercial delivery vehicle)
5. Inspect all wheels for existing damage, bent rims, or excessive runout before beginning
6. Mark wheel positions (LF, RF, LR, RR) with chalk or marker for reinstallation reference

Procedure

1. 1

   Lift vehicle and remove first wheel
   Position floor jack under front jacking point per owner's manual. Lift vehicle until tire clears ground. Place jack stands under frame rails for safety. Remove lug nuts and wheel assembly. Repeat for remaining wheels one at a time or work on all four if shop space allows.
2. 2

   Deflate tire and prepare for balancing
   Remove valve cap and check valve core for leaks. Deflate tire completely by removing valve core if wheel needs to be dismounted for cleaning, or maintain pressure if wheel is clean. Inspect TPMS sensor battery status if vehicle has monitoring capability.
3. 3

   Clean wheel mounting surfaces
   Use wire brush to thoroughly clean both sides of wheel rim, especially in areas where weights will be applied. Remove all old adhesive residue, dirt, and corrosion from weight mounting surfaces. Clean hub mounting surface on wheel to ensure proper seating during reinstallation.
4. 4

   Mount wheel on balancer
   Select proper cone or plate adapter for EDV 500 wheel bolt pattern and center bore. Mount wheel securely on balancer spindle, ensuring wheel is centered and seated flush against mounting plate. Hand-tighten pressure cup firmly but do not over-torque.
5. 5

   Input wheel specifications
   Measure and enter wheel diameter, width, and offset into balancer computer. For EDV 500, verify wheel size matches specifications (typically 16-18 inch commercial wheels). Select appropriate balance mode (dynamic balance recommended for commercial vehicle).
6. 6

   Perform initial balance measurement
   Lower balancer hood or guard and initiate spin cycle. Allow balancer to complete full measurement cycle. Note imbalance readings for both inner and outer wheel planes. EDV 500 commercial application requires balance tolerance of 0.25 oz or less per wheel.
7. 7

   Apply corrective weights
   Based on balancer readings, select appropriate weight sizes for inner and outer positions. For inner barrel, use adhesive tape weights if clearance to suspension components is limited. For outer rim, use clip-on or adhesive weights as appropriate for wheel type. Apply weights at exact positions indicated by balancer.
8. 8

   Verify balance correction
   Spin wheel again to verify balance correction. Balancer should show readings within 0.25 oz or green/acceptable range. If readings are still excessive, remove and reposition weights as needed. Repeat verification spin until proper balance is achieved.
9. 9

   Inflate tire and check pressure
   Reinstall valve core if removed. Inflate tire to specification listed on door jamb (typically 60-80 PSI for EDV 500 delivery application). Use accurate tire pressure gauge to verify exact pressure. Check for leaks around valve stem and TPMS sensor.
10. 10

    Remove wheel from balancer and repeat
    Carefully remove balanced wheel from balancer and set aside. Repeat steps 2-9 for remaining three wheels, maintaining organization of which wheel came from which position.
11. 11

    Reinstall wheels on vehicle
    Mount wheels back in their original positions (or new positions if rotating). Hand-thread all lug nuts to prevent cross-threading. Lower vehicle from jack stands until wheel makes light contact with ground to prevent spinning.
12. 12

    Torque lug nuts to specification
    Using torque wrench, tighten lug nuts in star/cross pattern to manufacturer specification. While no specific torque value is listed in database, EDV 500 commercial application typically requires 120-140 ft-lbs. Verify exact specification in owner's manual or on wheel itself. Make at least two complete passes in star pattern to ensure even torque.
13. 13

    Lower vehicle and perform final torque check
    Remove jack stands and lower vehicle completely to ground. Perform final torque check of all lug nuts in star pattern with wheels fully loaded. Verify TPMS system recognizes all four sensors if vehicle is equipped.

Reassembly

1. Verify all lug nuts are properly torqued to specification
2. Confirm all valve caps are reinstalled
3. Check that TPMS warning light is not illuminated on dash
4. Remove wheel position markings if no longer needed

Verification

• Test drive vehicle at various speeds (25, 45, and 60+ mph if safe) to verify vibration is eliminated
• Steering wheel should remain steady with no oscillation at all speeds
• No unusual tire noise or humming should be present
• TPMS system should show correct pressures for all four tires
• Re-check lug nut torque after 50-100 miles of driving
