A little more information please:-
Were they all bought at same time/place?
How much have they been left out in direct sunlight - and how strong?
What pressures have they been run at?
What loads? What speeds? A vaccine does not stop you catching a virus, or passing it on, or getting ill from it, really ill. It does reduce the likelyhood of you dying when really, really ill. Stay Alive - KEEP AWAY FROM PEOPLE.

I saw 3 D3's at Pacific Maroochydore last month that had these tyres with the damage
you specify , especially chipped blocks. How these tyres last is dependent upon the points
that Navigator details ,and any bad road surfaces that some here just have an affinity for .
Chunking is common with this tyre , esp with the heat that generates in the climate.
IMO I thought the tread was OTT for speed bitumen driving , and I think this causes
alot of the damage.
What % of original tread depth do you have remaining ?

canyonero,
I've had GG's fitted for 38,000 km and I did notice circumferential grooves around the tyres roughly in the centre of the tread. They were grooves and not wrinkles or gouges as you have described. This would have been maybe 8,000 km ago. The grooves have worn away since. To be clear, I use the GG's only on the bitumen and fit STT's for off-roading.
I don't have tread blocks chipping or cracking either. This is something that happened on a set of Cooper ST's on the D3 but this is another story.

I haven't noticed any tread blocks cracking, but I do have the central wear line around all 4 tyres. I wouldn't say it was a groove though, to me it seems like something to do with the moulding/mfr process and nothing to worry about. On mine, it is flush, but a slightly different colour, as if it was a different composite rubber running in a band all around the centre. D3 TDV6 HSE 2008 Buckingham Blue (current)

Had alook at mine. I can see a different rubber round the centre. Agree with redjelly that is is part of manufacturing process. If you think it is actually cracked there speak to the supplier. “There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

Mine too. I'd say it's where 2 halves are joined in manufacture?? If anything I'd say slightly raised / harder.
I'd say Nowt to worry about  Long succession of Disco's since 2001...
