I was trying to put together a spreadsheet/matrix of some of the foam 1/12th tires available to us these days. list out the PN's, color designations, durometer readings, natural v synthetic. I was looking back at old Parma, Jaco, new Gravity, CRC, BSR and trying to just make sense of it all for myself. Where I am at is a pretty good list of the PN's and designations, but lots of holes in the type of compond and durometers.
Has anyone else cared or tried to do this, maybe we could share some information?
