Data taken from a variety of sources
Fuel Consumption
Calculate your mpg. Tip: You can enter an mpg figure in the MPG field to just convert to Metric and U.S.
Tyre Heights
Compare different tyre and wheel combinations. To keep speedometer readings accurate keep to within 2.5%.
NB Not all combinations are available as tyre sizes. A tyre profile of 80%-82% is considered standard size.
Distance
Convert miles to kilometers and kilometers to miles.
