Wheel & tire calc 2

About

This calculator is meant to aid in finding alternative wheel and tire dimensions for a car. Input the measurements for two different wheel/tire combinations and you will get the difference between them so you can see if they will fit inside the fender.
For example if your car have 165/70 R14 and you want to exchange them for wider 17 inch wheels with a different offset.

Usage

Fill in the boxes below with the 2 wheel and tire specifications that you want to compare and hit "Calculate". This will produce an image beneath. The image then displays the two wheel and tire combos on top of each other (the first tire above and the second tire below), aligned at the mounting surface. Dimension lines will display how much they differ.

A selection must be made in all drop-down menus and text inputs below.
