Side-by-Side Tire Visualizer
Draw two or more tire sizes side by side at the same scale. See nominal diameter, sidewall and rim proportions as scaled silhouettes.
Display nominal tire silhouettes.

How Side-by-Side Tire Visualizer Works?
The Side-by-Side Tire Visualizer works by converting every tire's diameter, sidewall and rim into pixels with one shared scale and drawing the silhouettes next to each other on a common ground line. The tool uses 4 steps.
Enter the sizes
Type 2 to 5 sizes, for example 225/45 R17 and 225/40 R18.
Set the shared scale
The visualizer finds the tallest tire and sets the scale so that tire fills the drawing height, for example 300 px for 859.3 mm.
Draw each silhouette
The visualizer draws the outer circle, the rim circle and the sidewall band for each tire on the same ground line.
Label the dimensions
The visualizer prints diameter, sidewall and rim values under each tire in mm and inches.
Side-by-Side Tire Visualizer Formula
The Side-by-Side Tire Visualizer formula is Pixels = Millimeters × (H_canvas ÷ OD_max), applied to every dimension.
k = H_canvas ÷ OD_max (px per mm)R_px = OD ÷ 2 × kr_px = Rim × 25.4 ÷ 2 × ky_center = y_ground − R_px- H_canvas
- Drawing height (px)
- OD_max
- Tallest diameter in the set (mm)
- k
- Shared scale factor
Worked example
With a 300 px canvas and a tallest tire of 859.3 mm (285/75 R17), the scale is 0.349 px per mm. A 225/45 R17 tire draws 221 px tall, and the 285/75 R17 tire draws 300 px tall.
Side-by-Side Tire Visualizer Conversion Table
The Side-by-Side Tire Visualizer conversion table shows how 5 sizes convert into pixels on one shared 300 px scale.
| Size | Diameter | Drawn height | Drawn rim | Drawn sidewall |
|---|---|---|---|---|
| 225/45 R17 | 634.3 mm | 221 px | 151 px | 35 px |
| 225/40 R18 | 637.2 mm | 222 px | 160 px | 31 px |
| 245/35 R19 | 654.1 mm | 228 px | 168 px | 30 px |
| 265/70 R17 | 802.8 mm | 280 px | 151 px | 65 px |
| 285/75 R17 | 859.3 mm | 300 px | 151 px | 75 px |
What is Side-by-Side Tire Visualizer?
A Side-by-Side Tire Visualizer is a tool that draws tire sizes as scaled silhouettes next to each other. Numbers like +2.9 mm are hard to picture. A scaled drawing shows the difference at a glance.
All tires share one scale and one ground line, so heights, rim sizes and sidewall bands compare directly.
The silhouettes use nominal dimensions. Real tires show tread pattern, shoulder shape and sidewall bulge that the drawing leaves out.
