Yea but no.
If the rubber outer layer cracks exposing the cords, then road grit gets into the cords and abrades them internally.
The general consensus among RV and heavy truck operators is that tire cracking means "your tire is very close to failure".

Replacing cracked tires isn't a big deal, as long as "not crashing at speed" isn't a big deal.
Also I repeat again, for those who think they know better--
send pictures to the tire manufacturer and see what they say about the tires still being safe.
