How to Size Your Tires - Multiply the width by the aspect ratio expressed as a decimal (225 x 0.55 = 123.75).
- Convert the aspect height to inches (123.75 / 25.4 = 4.87).
- Multiply the aspect height by 2 (4.87 x 2 = 9.74).
- Add the inside diameter of the tire (16 + 9.74 = 25.74).
- Repeat for the size of the new tire.
