On another forum for MV Agusta a question was raised regarding the shelf life of a tyre. The following amswer was posted

A friend had a crash earlier this year on brand new tyres and couldn't figure out why (he was a competent rider who has had a wildcard entry into the WSB a few years ago). On investigation he came up with the following.

Tyres have a manufacture date on them and an unofficial use by date. An internet search will reveal that m/c tyres has less than 1/2 it's grip after 4 years and should never be used after 6 years.

The manufacture date is:
look for the letters 'DOT', then look for a number series at the end. The first two digits indicate the week of the year the tyre was manufactured and the last two indicate the year.

for the sample below the tyre was made in the 27th week of 2007
 
It is the same for vehicles tires and anything over 6 years is recommended not to be used. I think it was 20/20 or Dateline, were conducting an investigation on the subject since Sears and local tires business knowing about the issue and danger of it were selling old tires to costumers.
 
Yes - excellent info. For those looking, rear is on RHS of tyre, front is on LHS on stock Pirellis.
Bad news is my new tyres (just fitted) aren't so new.
Rear is 48th week '08! At least the front is 3609 - I guess that's the main one..
