Doubt you'll get any meaninful readings unless you use all brand new tyres of the same diameter. the first time you put additive on them they will drop 3-4 points then get slowly softer over following runs.
Diameter/ sidewall hight will also effect readings even in same conpound/brand

Thanks mate but my old mate the Madave Guru Gazza has worked it all out for me its just the digital reading +14 gives a bang on tyre shore every time.
So today with shore and bag all my tyres something to do this afternoon me thinks.

just spent all afternoon going through my tyres all makes sence now
