That tread separation is pretty strange. I agree that it's time to change brands.
Absolutely the brand.
A few years ago I put 6 new Toyo H/T Touring (same as shown in the above pics) on my dually. A few months after installation I got a recall notice, told me to bring the truck back to the dealer so they could check the batch numbers because certain batches were have tread separation issues. Which I did; dealer told me my tires were not covered by the recall and I was good to go.
Since then I've had tread separations on two of the Toyos. I had to pay for the replacements - no warranty coverage at all. Dealer and Toyo refuse to replace the other four tires even though they have barely 20,000 miles on them, and I expect they will fail also.
But it is just this particular model of Toyo tire. I've run Toyo Open Country Mud Terrains for years now on my very heavy 4x4 van; they are all chewed up now because of rocks but I've never even had a flat on one.
