I suspect, with 002'' increments and different wheel possibilities, we are talking more than a few minutes!

The rule is before you buy any tyres buy something to put them in, those little flip-top things from Maplins I told you about are ideal.

I hope you solve the issue....

I always keep a note of what tyres are on what cars. I number those little flip lids I mentioned earlier and have a list of what numbers corrospond to which tyres.

Tedious, and maybe a little anoraky, but you have already discovered the alternative.

Bear in mind the plastic gauges are OK as checkers more than being definitive.
