Comparison of hot to cold tire fuel economy. Technical report

Technical Report ·
OSTI ID:6369035
As part of a comprehensive tire rolling resistance measurement program, a tire study was conducted on 33 different sets of tires at ambient temperature (approximately 75F). Each set of tires was installed on the rear two wheels of a fully warmed-up vehicle. The vehicle was then driven over an FTP driving schedule on a single large-roll dynamometer and the emissions and fuel economy values were determined for each phase of the schedule. The fuel economy changes due to tire warm-up are summarized and analyzed. In addition, the effect of tire type, size and manufacturer on the fuel economy values are investigated. Finally, the effect of tire warm-up on tire rolling resistance is discussed.
