How the Printable Tire Size Reference Generator Works
This generator works by building a customized size chart and formatting it for print or PDF. You choose the rims, widths and aspect ratios to include.
- Choose the rim sizes, for example 18 in and 20 in.
- Choose the widths and aspect ratios.
- Preview the chart with diameter, sidewall, circumference and revs per km.
- Print or save it as a PDF.
The Formula
The formula applies the standard tire equations to each chosen size and lays the results out for an A4 or US Letter page.
D (mm) = (Rim × 25.4) + 2 × (Width × AR ÷ 100) C (m) = π × D ÷ 1,000 Revs per km = 1,000 ÷ C (m)Worked example row: 275/60R20 has a 165 mm sidewall, an 838 mm (33.0 in) diameter, a 2.633 m circumference and 380 revs per km.
Conversion Table
The conversion table is a sample printable chart of 9 SUV and truck sizes on 18 in and 20 in rims. Diameters run from 29.5 in (749 mm) to 34.1 in (866 mm).
The chart uses metric and inch diameters together. A printed copy suits a shop wall or a garage.
