I was looking around for tires and I noticed Hoosier has the D10 and D12 listed for rears. I have a 74-10-13 D12 on the lr and a 25.5-10-13gtw gf-3 (Old and used up too) on the rr. now but the rules say D15 or SP2 Hoosier and SD-38 American Racer as the minimum tread. Is this a typo in the rules or do I need to start hunting down legal tires? Any particular tire size to start with as I'm new at this and will be learning as I go. Thank you
