How to Read a Tire Size

Tire sizes follow a standardized format. Understanding each part helps you find the right replacement or alternative tires for your vehicle. Here is how to decode a tire size like 235/45R18.

235
Section Width (mm)
The tire width from sidewall to sidewall in millimeters. A 235 tire is 235mm (about 9.3 inches) wide.
45
Aspect Ratio (%)
The sidewall height as a percentage of the width. A 45 means the sidewall is 45% of 235mm = 105.75mm tall.
R
Construction Type
R stands for Radial construction, the most common type. Nearly all modern passenger vehicle tires are radial.
18
Wheel Diameter (in)
The diameter of the wheel the tire fits, measured in inches. This tire fits an 18-inch wheel.
235/45R18

Tire Size Database FAQ

Common questions about VehDB's tire size database, Tire Finder, and tire sizing.

Use VehDB's Tire Finder wizard: select your vehicle's make, then choose the model and year. VehDB will display the OEM tire size and all compatible alternative sizes. You can also find the tire size on your vehicle's door jamb sticker, owner's manual, or on the tire sidewall itself.
OEM (Original Equipment Manufacturer) tire sizes are the exact sizes specified by the vehicle manufacturer for your car. Alternative tire sizes are compatible sizes that fit your vehicle's wheels and wheel wells while maintaining similar overall diameter and performance characteristics. VehDB lists both OEM and alternative sizes for every vehicle.
Plus-sizing means increasing the wheel diameter while adjusting the tire width and aspect ratio to maintain a similar overall tire diameter. For example, moving from a 16-inch to a 17-inch wheel with a lower-profile tire. Plus-sizing can improve handling and appearance but may affect ride comfort. VehDB's alternative sizes include plus-size options where applicable.
A tire size like 235/45R18 breaks down as follows: 235 is the tire width in millimeters, 45 is the aspect ratio (sidewall height as a percentage of width), R means radial construction, and 18 is the wheel diameter in inches. So a 235/45R18 tire is 235mm wide, has a sidewall height of 105.75mm (45% of 235), and fits an 18-inch wheel.
Yes. VehDB's tire size database cross-references tire sizes with the car database. When you view a specific tire size, you can see all vehicles that use that size as OEM or as an alternative. This is helpful when comparing tire prices across shared vehicle fitments.
