Very minor, if not insignificant, component IMO. Cars, and other
vehicles, used for speed record attempts invariably use the narrowest
tyres possible (which results in an increased loading on the contact
patch).
IIRC Donald Campbell's Bluebird (which broke the then land speed
record on Lake Eyre circa 1960's) weighed more than 5 tonnes. It
managed around 650kph (with a very long run up).
