General Grabber HTS were original OEM tires for 2022 Lightning Lariat ER. Hankook AT tires were an option. Now it appears Hankook AT have replaced the General Grabbers as OEM. Probably a supply chain issue but who knows for sure. I have been very happy so far with the General Grabber HTS. Smooth, quiet, very little if any hydroplaning and good braking. Rated very highly in Consumer Reports, actually just ahead of my favorite tire in this class Michelin Defender LTX. Only 3k miles on my truck so obviously too early to tell on mileage rating but hard to believe they will compete with the Michelins in mileage especially on such a heavy truck.
