How the Tire Size Chart Generator Works
This generator works by building a table of dimensions for a set of sizes you choose, such as every aspect ratio of one width on one rim. It outputs diameter, sidewall, circumference and revs per mile for each size.
- Choose the width, for example 225 mm.
- Choose the rim, for example 17 in.
- Choose the aspect ratio range, for example 35 to 65.
- Read the generated chart.
The Formula
The formula applies the standard tire equations to every row.
Sidewall = Width × Aspect Ratio ÷ 100 D = (Rim × 25.4) + 2 × Sidewall C = π × D Revs per Mile = 63,360 ÷ C (in)Worked example row: 225/55R17 has a 123.75 mm (4.87 in) sidewall, a 679.3 mm (26.74 in) diameter, an 84.0 in circumference and 754 revs per mile.
Conversion Table
The conversion table is a generated chart for a 225 mm width on a 17 in rim, with 7 aspect ratios from 35 to 65. Diameters run from 23.20 in (589 mm) to 28.52 in (724 mm).
Each 5-point aspect step adds 0.89 in (22.5 mm) of diameter and removes 23–32 revs per mile.
| Size | Dia (in) | Dia (mm) | Sidewall (in) | Circ (in) | Revs / Mile |
|---|---|---|---|---|---|
| 225/35R17 | 23.20 | 589 | 3.10 | 72.9 | 869 |
| 225/40R17 | 24.09 | 612 | 3.54 | 75.7 | 837 |
| 225/45R17 | 24.97 | 634 | 3.99 | 78.5 | 808 |
| 225/50R17 | 25.86 | 657 | 4.43 | 81.2 | 780 |
| 225/55R17 | 26.74 | 679 | 4.87 | 84.0 | 754 |
| 225/60R17 | 27.63 | 702 | 5.31 | 86.8 | 730 |
| 225/65R17 | 28.52 | 724 | 5.76 | 89.6 | 707 |
What Is the Tire Size Chart Generator?
The Tire Size Chart Generator is a tool that tabulates dimensions for a group of tire sizes you pick. It replaces running the diameter calculator once per size.
Shops use charts to explain options to customers. Owners use them to compare a range of profiles at once.
Common Uses
This generator has 4 uses: customer handouts, profile comparison, catalog building and teaching.
- Make customer handouts: Print a chart for one wheel size.
- Compare profiles: See all aspect ratios side by side.
- Build catalogs: Generate dimension data for listings.
- Teach sizing: Show how aspect ratio changes height.
