Steps for a DIY Alignment with String

Pro Tip: After the DIY wheel alignment is complete, we recommend bringing the car to a shop for professional alignment.

1. Read the PSI of Each Tire

Take a reading of the psi of each tire and confirm the reading is accurate.

2. Place Cardboard Underneath the Tires

Stack two pieces of cardboard and place them behind the worn tire and the opposing tire on the opposite side.

Back the car up so the tire is centered on the cardboard.

3. Center the Steering Wheel

Turn the steering wheel back and forth and adjust it as close as possible to the center so it’s centered

4. Tighten String to Two-Step Stools Within Reaching Distance of the Tires

Wrap a piece of string between two step stools and place them within reaching distance of the tires.

5. Make Sure the String Reaches the Center of the Tire and Is one Inch from the Center Cap

Measuring the height of the string to the center of the tire

Measure the height of the string and make sure it reaches the center height of the tire. Do this for both sides.

Measuring the length of the string from the center cap

Place the string about an inch from the center cap and make sure it’s tight and not touching a part of the car.

6. Measure the Distance Between the Step Stools and Make Sure They Match
