OTR Trading made yet another handy application for all the 4x4 extreme fanatics out there. As any 4x4 or car enthusiast should know, when you are dealing with formulas dealing with gear ratios and such - you will need to know the tire diameter in inches. This calculator will offer just that for you and allow you to quickly work out the inches diameter from your metric size of your tires for your 4x4 or your normal road car.

The great part about this calculator is that you can work out any of the data you are missing and so it is not only a tire diameter calculator. Let's start with its basic functionality of working out the tire diamter for your 4x4 vehicle:
You will enter the specifications of your tire (for your P or LT which mean passenger vehicle or light truck or 4x4). For example if you enter LT275/95/R18 into our tire size calculator it would easily tell you that the tire diameter of your 4x4 is 38.6 inches. It will also be able to tell you the section width as well as the section height.

A fantastic feature of this calculator is that it lets you calculate any of the values if you enter the three other values.

This calculator lets you work out the following, all in one!:
- You can solve the section width of your 4x4 light truck / vehicle or normal for your normal road / passenger car.
- You can solve the aspect ration (width) of your 4x4 tires.
