At 9pm, TPMS alarmed on slow leak. I could hear the air escapingwhen I investigated.
First tire was a cracked stem.
Second tire was a partial delamination of the tread requiring replacement.
Manufacture date is 1919 - 2-1/2yrs old
I haven't contacted HiSpec yet but I'm looking to replace all tires.
My history with tires is once one starts tread separation the rest are close behind. I've had similar issues with a Chinese OEM tire and Hercules tires. I'm looking at Goodyear Endurance tires.

Welcome to the forum.

The cracked valve stem you can't blame on the tire. I have the same size tires and replaced my OEM tires over 5 years ago with Carlisle Radial Trail HDs. Don't know the miles but typically they age out before the tread wears out. Personally, I'll be replacing them next spring with the same tires.
