That type of cracking is typical of extended heat exposure, drying the ozone protective chemical agents out of the rubber. This can be exacerbated by chemical exposure through harsh cleaners, road coatings for snow/ice, etc.
Socal sun eats tires! Same with norcal sun. Once tires are 5+yrs old its a fast down hill run in tire decomp. Rubber continues to cure add sun / heat it cures quicker, as it cures its less flexible so any flexing will cause cracking etcYeah, that is what I would see but living in San Diego, CA we don't get extended heat nor do I use any cleaners (outside of car wash soap). We figured it was a bad batch of rubber.

Truth. My driveway aligns East/West, so my van has one pair of tires that face South for all the stretches when I'm not out having fun. Even with frequent 5-tire rotation strategy, I can see a noticeable difference on the tires I pull from the South side of the van vs. the North.
I don't mean to underplay the fact that you almost certainly got a badly made set of tires. Sun/heat do their thing, but that's additive damage and you should have had better life from your set.I had thought the same thing, since I park on the street in a East/West config. I do not cross rotate so driver and pass side tires are always on the same side. I totally would have expected this to be on the south facing tires and had I only saw them on that side, it would have made sense. Give the north side was as bad or worse with cracking, made no sense.

People lacking in obvious basics are everywhere.
I could probably end the post there...
But a few weeks ago had a good tire story. Driving home with my wife and a car passes us on the freeway with sparks flying off the rear tire as the belts hit the asphalt. I comment on the overall intelligence of that person... well over 80 mph on bald tires down to the cords. She was in the process of accusing me of being a drama queen when we came around a corner and up on a 4 car pile-up caused by that guy’s blowout.
Amazingly, she took it back and agreed that I “might have a point”... it’s a big win!
Good follow up. Checking for condition is one thing, but date codes are another.Very good reminder, two weeks ago I checked my tires dates on my 68 camaro, tires looked new, always kept clean, shined and care is garage kept and rarely driven anymore, the tires looked new, but I was shocked to see the tires were dated 1999., I think I put them on in 2001...yikes. I immediately ordered replacement set.
To be fair to the Discount Tire tech, he'd have had to crawl under my van to check the codes (as I'd done). The confusion only lasted a few moments between him approaching my van, measuring the tread depth, then asking why I wanted new tires. As soon as I told him how old they were, he got it, and to his credit, he even confirmed the date codes on all 5 tires once he had the van on the rack.“The tread was good enough that even the Discount Tire guy was confused on why I was shopping tires until I told him about the age.”
Yup, similar experience at America’s Tire here in town. Had to “teach” the young tech how to find and read the date code on tires. Not quite sure why they use such a cryptic date code but I’m sure it must be a corporate conspiracy. ?
