Re: Which kind of tire warmers??
i am no authority on the subject but i have taken a few siminars on tires, specifically motorcycle tires, even more specific sportbike street and racing rubber. some held by michelin, and good year/dunlop.
the tire manufacturers recommend keeping them on a low setting inbetween sessions, yes turn them on atleast one hour before use, but you dont always have an hour.... those same crew chiefs and serious racers change tires after every session...... for a club level, once a month trackday rider, we cant afford new race rubber every day or some of us every weekend, so heat cycles are important to keep cold tears from destroying the tire
if you over heat a tire it will kill the life of the tire. say tire's maximum performance is 'X'. the first time you heat the tire up your performance and grip level will be 'X', the second time it will be X-1, the third x-2, and so on, yes if you bake your tire on high all day they will get greasy, slick, and hard,
a racing compound tire does take a lot longer to heat up compared to a street tire. just bc the contact patch temp is 185 degrees doesnt mean the carcass is at operating temperature.
there are more than just a couple factors in todays tires, they are technologically advanced, i race the ccs amateur circuit and i doubt i will ever ride the limits of my tires
the next time you go to the track, do your first couple sessions on cold race rubber, then after lunch switch to warmers
