Estimate Tire Dimensions from a Photo
Need to know your tire size for a replacement but cannot read the sidewall numbers? Our AI measures the overall diameter, width, and visible dimensions of your tire from a photograph. This gives you a starting point for finding compatible tires at auto shops or online retailers.
Understanding Tire Size Numbers
Tire sizes are expressed in a format like 225/45R17, where 225 is the width in millimeters, 45 is the aspect ratio, and 17 is the wheel diameter in inches. While our tool estimates physical dimensions from a photo, reading the actual sidewall code is always preferred for purchasing replacement tires.
Works with Car, Truck, Motorcycle, and Bicycle Tires
Our measurement tool handles tires of all sizes and types. Photograph any tire from the side to get an overall diameter estimate, or from the front to gauge the width. Including a person, car door, or other known object in the frame helps the AI calculate dimensions more accurately.
