a) within all the principal grooves that normally contain moulded tread depth indicators, or

b) if the tyre does not normally have moulded tread-depth indicators (such as some retreaded or vintage tyres), across at least three-quarters of the tread width.

Just thought that I would throw that into your discussion
True Carlo but been outta date with what LTSA say's doesn't matter as this is a ruling for "Motorsport car racing" and is currently in the MSNZ manual so nothing needs changing just enforcement so Ray may as well use this!! also this helps alight ERC and Arrows to MSNZ and the H&C commission which Ray is eager to do so is gotta be good for old car racing! true?
