Tire Rotation

This procedure rotates all four tires on a 1966 Chevrolet Corvette to promote even tire wear and extend tire life.

Warnings

Tools required

Preparation

1. Park vehicle on level, solid surface and engage parking brake
2. Place wheel chocks behind rear wheels
3. If wheels have not been rotated before, mark each tire position (LF, RF, LR, RR) with chalk to track rotation pattern
4. Verify wheel type (steel or alloy) for correct torque specification

Procedure

1. 1

   Loosen all lug nuts
   With vehicle still on ground, loosen all lug nuts on all four wheels approximately one full turn. Do not remove them completely. The 1966 Corvette uses a 5-lug pattern with 13/16" lug nuts.
2. 2

   Raise front of vehicle
   Position floor jack under the front frame crossmember (behind the radiator support). Raise front end until wheels are off the ground, then place jack stands under the front frame rails approximately 12 inches behind the crossmember. Lower vehicle onto jack stands.
3. 3

   Raise rear of vehicle
   Position floor jack under the rear differential housing. Raise rear end until wheels are off the ground, then place jack stands under the rear frame rails just forward of the rear suspension mounting points. Lower vehicle onto jack stands. Verify all four wheels are off the ground and vehicle is stable.
4. 4

   Remove all wheels
   Remove the lug nuts completely from all four wheels and set them aside. Remove all four wheels and place them near their new mounting positions according to rotation pattern. For the 1966 Corvette with rear-wheel drive and non-directional tires, use a rearward cross pattern: left front to right rear, right front to left rear, left rear to left front, right rear to right front.
5. 5

   Inspect tires and brake components
   With wheels removed, inspect each tire for uneven wear patterns, cuts, bulges, or embedded objects. Check tread depth across all tires. Visually inspect brake drums or rotors and backing plates for damage or excessive wear. Note any issues for future service.
6. 6

   Mount tires in new positions
   Install each wheel onto its new hub position following the rotation pattern. Thread all 5 lug nuts onto each wheel by hand to prevent cross-threading. Ensure the wheel is seated flush against the hub before tightening.
7. 7

   Hand-tighten lug nuts
   Hand-tighten all lug nuts on all four wheels in a star pattern (tighten one, skip the next, tighten the opposite, continue pattern). This ensures the wheel seats evenly on the hub.
8. 8

   Perform initial lug nut torque
   Using a lug wrench or impact wrench, snug all lug nuts on all four wheels in a star pattern. Do not apply final torque yet, just bring them to finger-tight plus resistance. This step prevents wheel movement when lowering the vehicle.
   ⚠Do not apply full torque while vehicle is on jack stands, as this can cause instability.
9. 9

   Lower vehicle to ground
   Raise vehicle slightly with floor jack to unload jack stands. Remove all four jack stands. Carefully lower vehicle completely to the ground. Rock vehicle gently side-to-side to settle suspension.
10. 10

    Apply final torque to lug nuts
    Using a torque wrench, torque all lug nuts to specification in a star pattern. Torque all lug nuts to approximately 70 lb-ft (95 Nm) for the original steel wheels. Complete the star pattern twice on each wheel to ensure even torque distribution. Verified detail (References an alloy wheel torque spec that does not apply to the factory steel-wheel-equipped 1966 Corvette.): Lug Nuts - Steel Wheels
    Torque spec

    Lug Nuts - Alloy Wheels130 Nm (96 lb-ft)

    Lug Nuts - Steel Wheels140 Nm (103 lb-ft)

Reassembly

1. Store jack and jack stands in proper location
2. Clean any chalk marks from tires if desired
3. Record tire rotation in vehicle maintenance log with date and mileage

Verification

• Verify all lug nuts are torqued to specification using torque wrench
• Check that no tools or parts are left under vehicle
• Test drive vehicle at low speed and listen for any unusual vibrations or noises
• Recheck and retorque all lug nuts after 50 miles of driving as specified for both wheel types
