FIELD: transport engineering; measuring facilities.
SUBSTANCE: invention provides two methods of measurement of automobile run taking into account changing of tires of one size-size by tires of other type-size. Coefficients of proportionality or run increment measurements errors for type-sizes of tires which can be mounted on automobile are put into memory of automobile measuring system. Having replaced the tires, coefficients of proportionality or run increment measurement errors corresponding to type-size of installed tires are take from memory and used for measuring run of automobile. Said measurement is based on generation of pulses whose number is proportional to run o automobile. Group of inventions provides higher accuracy of measurements.
EFFECT: provision of accurate measurement of automobile run.
