Were they relatively fresh date codes (not 3 or 4 year old
stock)? I have not seen any problems surface that early, but I did
have cracking problems on some 4 year old Michelin Hydroedge a few
years back and have had multiple problems on Continental OE on
F250 truck as well as Trailer and daughter's Nissan Altima.
All my problems about 3 to 4 years after Date of Manufacture. And
dealers will not cover unless you replace with same Continentals
and even then its prorated based on 5 year life so not much use. I
actually had pieces of tread chunk out on both the Trailer and the
F250 (both were LT tires) and Ford dealer service guy said they
have had similar issues with Continentals - recommended I replace
with Goodyear which I did - but that is another story - finally
got Michelins and did not have any further problems.
Impression is they are adding too much solids (high silica
content?) and it is decreasing long term flexibility / extension
capabilities. So it may be unique or more problematic on a
particular rubber formulation / tire model.
