One thing I always been thinking.., In F1, cold tyres runs faster right? or is it the opposite?
hot should be faster if I am not wrong. It is warming up theory.
and one more thing, Bigger profile tyres doesn't also means more distant to complete 1 revolution? if so, it would have appeared in the odometer that it cover lesser distant? thus the illusion for higher FC?
this depending on the actual profile of the new rims + tyre. Definitely there is a rounding up or down error for the odometer. It could be better (i.e. odometer show more mileage then actual) or could be worst. Typical should be fall under +/-1% to reduce such error. Then again.. it is still up to individual. Some just dont really care whether it is within 1% difference or not

When the tyre compound gets hot, it becomes more "sticky" aka better traction.. esp for semi slick or slick tyres :)

Simply put it.. over size circumference = under clock on odometer, under size circumference = over clock on odometer

Thanks lorddraco and kanzo, so means when people say higher fc when rim change to bigger size does not necessary mean fc really higher. 1%? that really small difference.
Thank u guys.

Simply put it.. over size circumference = under clock on odometer, under size circumference = over clock on odometer
under size = over clock on odo???
that mean we will clock high mileage = more servicing basd on milage = warranty used faster?
can we reset any setting to suit the circumference size?

yes and no. If you upsize your rim but maintain similar over circumference ie a lower profile tyre you wun experience much overclock or under clocking. the FC goes up coz of the additional weight from a bigger rim.. the car will need a higher torque to overcome the additional weight ( start up torque ) plus acceleration affected so maybe you will step harder on acc resulting FC going up. :devil2:
