Been running Hankook AH12's for 5 years and 30K miles, very satisfied but had an inside dual blow-out on a tire that was 7 years old and hence needed to shop.
Replaced both inside duals (other was also 7 years old-datecode ignorance on my part).
Ended up putting 2017 date code Ironman I-502's made in China. These are 275/70/22.5's and are a J rated 18ply tire. Price was significantly lower than the Hankook's which I could not find locally.
After a 2500 mile trip up to Nashville, down the Nachez Trace and thru Mississippi, Alabama and the panhandle for Florida they have performed as expected (that is , I cannot tell the difference from their smooth riding predecessors).
Ironman is a subsidiary of Hercules and is really just re-branded as Hercules also has a line of I-502 all position commercial tires.
I know Chinese tires are a controversial subject, but J rated tires for 275/70/22.5 tires is kind of cool IMHO.
