How old are the Pirellis letters not necessarily in the right order

Had to go to North Wales at a good lick, last night in some of the worst wet weather I've encountered whilst driving. Went through several areas of inches deep water along a twisty road. Car and tyres behaved superbly. The tyres? Nexen Rodians! Previous cars:
S-Max 2007-2013 (only diesel I've had, good car but expensive when diesely bits go wrong, so what's the point?)
Galaxy 2001-2007
Mondeo Estate 1997-2001
Sierra Estate 1993-1997
Uno Turbo 1987 -1993
Fiesta 1984 - 1987
Fiat 127 1982 - 1984

Nexen are OK on a FFRR - not so much a performance car - they are considered mid-range.

I'd avoid economy & particularly budget brands
