jdlamantia Posted August 12, 2011 Report Share Posted August 12, 2011 In the rules for the Bomber class it states no 50 or 60 series tires. Is that referring to thread width or aspect ratio. Or both? Quote Link to comment Share on other sites More sharing options...

top_shelf_12 Posted August 12, 2011 Report Share Posted August 12, 2011 Think it's meant basically no racing tires, pretty sure the Bombers use street DOT tires. I'm sure Owen or someone from the track will give you a answer though. Quote Link to comment Share on other sites More sharing options...

No 60 or 50 series tires." Quote Link to comment Share on other sites More sharing options...
AARC67 Posted August 12, 2011 Report Share Posted August 12, 2011 No 50 or 60 series tire is being referred to as the side wall aspect ratio, indicating rim to tread height. Quote Link to comment Share on other sites More sharing options...
