Re: Tires

OK maties
Your dead right Mayf stuffed up big time using coefficient of friction , it
should have been coefficient of rolling resistance  I use this little dity to
calculate rolling resistance CCRWTVG(5-15%) where CCR= coefficient of rolling
resistance (see note ) WT = total weight of vehicle and driver / rider  (
newtons) VG = ground velocity ( meters per second)
note I use 0.013 as an average figure for calculations
does the radius and or the width of the tyre change the CCR ? my knowledge in
this area is sadly lacking  still waiting for an explanation why 13inch dia is
no good and 16 inch dia is good?
