What make are the tyres?

What age are the tyres?

Fronts are BF Goodrich
Rears are Kleber C501Z
Bought wheels and tyres in March 2011 so dont know age of tyres
Had them refurbished(tyres off) in June 2011

The date is a 4 digit number printed in a little 'tablet' on the tyre.
If you post up the 4 tyres individual code I will know.
Thanks!
