I'm gonna be racing on a 1/4 mile dirt track. It is pretty narrow and not banked. Its like the completly opposite of the other track This is a hard question to answer but what would be my best bet on tires and sizes. The 2 times i raced there last year I had my 215/65/15, which are the tires i use for the other track. I know I need to at least get 14's but i dont know about the other 2 numbers. I'm pretty sure 215 is to big but how small do i go 195?185? lower? What do you guys run on a track like this. Thanks in advance.
