We will be going through tires about one set per two races, give or take. We would like to have two sets on hand, one on the car and one as a backup. We are looking at the Falken Azenis RT416k+ for our tires in the 215/45/r17 size which are about $125 per tire. All we are asking is for the tires to be covered and we will handle the taxes and other fees to go with. In return, we will place a 4″ tall sticker on each side of the car.
