TireSizer

Own a car or truck? Need to replace tires? TireSizer is an easy and fun to use tire size calculator and provides other useful information about your vehicle's tires. You can use the input sliders or keyboard text labels to 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.

TireSizer uses your passenger or light truck tire size data such as P235/75/R15 (tread width, aspect ratio and rim diameter).

TireSizer also works with flotation truck tire sizes such as 31x10.5R16, high flotation agricultural tires 66x44.00-25, high flotation forestry tires 68x70.00-32, and large P-metric flotation tires 700/55-34 and 850/50-30.
