Step-by-Step Instructions

Follow these steps carefully

Check and set cold tire pressure from the door-jamb sticker

Park level, brake set, engine off. Read the door-jamb label for your trim's cold pressure — not the sidewall maximum. Check all four cold (3+ hours parked), inflate or bleed to match, refit caps. An accurate baseline prevents false TPMS warnings.

Loosen the lug nuts and lift the vehicle safely

Crack nuts a half-turn on the ground in crisscross order — don't remove yet. (Spec: 65–79 lb-ft / 9–11 kgf-m.) Jack at the side-sill lift points onto stands; never under a jack-only car. Chock the grounded wheels.

Rotate the tires in the forward-cross pattern

FWD forward cross: fronts straight back same-side, rears cross to opposite fronts, about every 7,500 miles. Directional tires (sidewall arrow): same-side front-to-back only. While wheels are off, check tread depth, feel for feathering or cupping, look for cuts, nails, bulges.

Reinstall the wheels and torque the lug nuts

Hang wheels, hand-start every nut, snug in a star pattern. Lower until tires touch, torque to 65–79 lb-ft in star order, two passes. Fully lower, final check with full weight on tires. Recheck lug torque after 50–100 miles — nuts settle on the studs.

🔧 Mechanic's note — Ray Delgado

That 50–100 mile recheck isn't optional — lug nuts genuinely settle into their seats. I've found them finger-loose at 200 miles when it was skipped.

Let the TPMS relearn and verify the job

Final cold pressure check against the sticker. Still on: recheck pressures first. Flashing: sensor fault. Log the mileage for the next rotation; confirm no new vibration or pull on a test drive.

🔧 Mechanic's note — Tom Becker

Log the mileage now, not later — 'about 7,500 miles ago' is exactly how rotations get forgotten. I jot it in a glovebox notebook with the pattern used, so the next rotation isn't a guessing game.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

• Inflating to the sidewall maximum instead of placard PSI
• Using the wrong rotation pattern for directional or staggered tires
• Relying on an impact gun without final torque verification
• Assuming a TPMS light clears when a tire or sensor is damaged

Tools You'll Need

Tire-pressure gauge and air compressor or pump Floor jack, rated jack stands, and wheel chocks Lug wrench and calibrated torque wrench

⚠️ Safety First!

• Informational DIY. EZ Car Fix is not a shop.
• Use the door-jamb placard PSI, not the tire sidewall maximum.
• Never work under a vehicle supported only by a jack.
• Confirm directional, staggered-size, and TPMS requirements before selecting a rotation pattern.
