Tire Size Calculator

A tire size calculator can reveal itself an invaluable help when you are shopping for new tires.  A good tire size calculator can quickly calculate the height of your vehicle's tires and axles when you want to replace your tires or rims with wider or narrower sizes, or taller or shorter sizes to raise or lower your vehicle.

You need to know how to read the information.  If you enter a tire size calculator tire size, a variety of information is back.   Most tire calculators offer a lot of information, but most of that is primarily for advanced users.   Your main concern is usually finding a tire size that is very close to stock height.   After doing some research, always consult a tire professional before switching tire sizes.

Usually, 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.
