Tire Mount and Balance

This procedure covers the removal, mounting, balancing, and installation of tires on a 2025 Rivian EDV 500 commercial delivery van with dual motor AWD configuration.

Warnings

Tools required

Parts

• Tires (set of 4) × 4 — Use OEM specification or equivalent size rating
• Valve stems (TPMS compatible) × 4 — Use OEM specification
• Wheel weights (adhesive or clip-on) × 1 — As needed for balancing

Preparation

1. Park vehicle on level, solid surface and engage parking brake
2. Place wheel chocks behind wheels that will remain on ground
3. Verify replacement tires match OEM size, load rating, and speed rating specifications from door placard
4. Inspect TPMS sensors on existing wheels to ensure compatibility with new tires
5. Loosen all lug nuts on wheels to be serviced approximately 1/2 turn before lifting vehicle
6. Identify proper jack points per Rivian service documentation (typically reinforced frame points behind front wheels and ahead of rear wheels)

Procedure

1. 1

   Lift and secure vehicle
   Using hydraulic floor jack at designated front or rear lift point, raise one end of vehicle until wheels are clear of ground. Immediately place jack stands under proper support points and lower vehicle onto stands. Verify stability before proceeding. Repeat for opposite end if servicing all four tires.
2. 2

   Remove wheels from vehicle
   Finish removing lug nuts in star pattern and remove from studs. Carefully remove wheel and tire assembly from vehicle and place on clean work surface. Note wheel position (FL, FR, RL, RR) if reinstalling same wheels. Inspect wheel studs and hub face for damage or corrosion.
3. 3

   Deflate and break tire bead
   Remove valve cap and depress valve core to fully deflate tire. Use tire machine bead breaker to separate tire bead from wheel rim on both sides. Work around entire circumference to ensure bead is completely free from rim before attempting removal.
4. 4

   Remove tire from wheel
   Mount wheel on tire machine turntable and lock in place. Position mounting head over bead and rotate turntable to work top bead over rim edge, then repeat for bottom bead. Remove tire completely from wheel. Inspect wheel for damage, corrosion, or cracks that would prevent proper sealing.
5. 5

   Inspect and service TPMS sensor
   Carefully inspect TPMS sensor valve stem for damage or corrosion. If replacing valve stem, remove sensor retaining nut and extract sensor. Install new valve stem with sensor, ensuring proper orientation and gasket sealing. Hand tighten sensor nut, then torque to specification per Rivian service manual (specification not available in database).
6. 6

   Mount new tire to wheel
   Apply liberal amount of bead lubricant to both tire beads and wheel rim edges. Position tire onto wheel with direction indicator (if applicable) facing outward. Use tire machine to press bottom bead over rim edge first, then work top bead over rim. Ensure TPMS sensor is not contacted or damaged during mounting process.
7. 7

   Seat tire beads
   Install valve core and inflate tire gradually while monitoring bead seating. You should hear and see both beads pop into rim seat position, typically between 25-40 PSI. Once beads are fully seated, adjust pressure to approximately 10 PSI below final specification for balancing. Check for air leaks around bead and valve stem.
8. 8

   Balance wheel and tire assembly
   Mount wheel/tire assembly on balancing machine and secure with proper cone or flange plate. Lower hood and initiate spin cycle. Machine will indicate heavy spots requiring correction weight. Install wheel weights at positions indicated by balancer, using adhesive weights on inner barrel or clip-on weights on outer rim flange. Re-spin to verify balance is within 0.25 oz or less.
9. 9

   Set final tire pressure
   Inflate tire to pressure specification listed on vehicle door placard. For EDV 500 commercial van, this is typically 60-80 PSI depending on load configuration. Use accurate tire pressure gauge to verify. Install valve cap to prevent contamination and moisture entry.
10. 10

    Repeat for remaining wheels
    Complete steps 2 through 9 for each remaining wheel that requires new tire mounting and balancing. Maintain organization of wheels by position if rotating tire locations during this service.
11. 11

    Install wheels on vehicle
    Clean hub mounting face with wire brush if necessary. Align wheel onto studs and push fully onto hub face. Install lug nuts by hand, threading each at least 3-4 turns to ensure proper engagement. Using star pattern, snug all lug nuts gradually with lug wrench before final torquing.
12. 12

    Torque lug nuts to specification
    With wheel still suspended, use calibrated torque wrench to tighten lug nuts in star pattern to proper specification. While exact specification is not available in current database, typical Rivian commercial vehicles use 140-160 ft-lbs. Consult vehicle service manual or door placard for exact value. Make at least two complete passes in star pattern to ensure even seating.
13. 13

    Lower vehicle and perform final torque check
    Raise vehicle slightly to remove jack stands, then carefully lower vehicle completely to ground. Once vehicle weight is on wheels, perform final torque check of all lug nuts in star pattern to specification. This ensures proper clamping force with wheel under load.

Reassembly

1. Verify all lug nuts are torqued to specification after vehicle is lowered and weighted
2. Install center caps or hub covers if equipped
3. Reset TPMS system using Rivian diagnostic tool or by following driver information display procedure (typically drive above 20 MPH for 10 minutes)

Verification

• Use TPMS scanner or vehicle display to verify all four tire pressure sensors are transmitting and reading correct pressures
• Test drive vehicle at low speed (15-25 MPH) and verify no vibration or pulling occurs
• Perform higher speed test (45-55 MPH) to confirm proper balance and no vibration at highway speeds
• Re-check lug nut torque after first 50-100 miles of driving
• Visually inspect all wheels to ensure proper seating and no gaps between wheel and hub
• Verify tire pressures match door placard specification after temperature stabilization
