Thanks for doing this Marty! FYI guys- the tires are in the left white pit-box, upper left side. Near them is the sign-out sheet; please take a max of two pairs (4 total).
NOTES
These are ‘new old-stock’ – they do not have the ribs or the severe divots the new tires (from PSR) have. They do have a slight center molding flash and shallow molding divot/nipple.
You need to use the HUDY or the P&N truers – the newest truer does not have a 3mm axle yet.
Avoid using lighter fluid – it accelerates the gumming; just true slow (1.8amp? at 3v)
Don’t try and get rid of the divot, just get rid of the flash and get an even tread-face.
20.9mm trued diameter gives you the better roll-out Marty mentioned and leaves enough meat for two(?) races (and associated practice).
*Roll-out – effectively higher gear ratio (like having a smaller spur) giving more forward movement covered for every turn of the pinion.
