Believe it or not, I got over 20 years out of a set of Armstrong Hi-Power Lugs. Bought the tractor used in 1990 and the tires were relatively new then. Replaced them in 2010 with Co-op radials.
Same tractor has a Kelly 10.00-16 tri-rib on the front purchased in 1990. Still going today. No loader of course.
Most any 23 degree Firestone rear will last 20 yrs. They will finally go flat when the cords in between the lugs wear out.
I don't want a Goodyear on the place.
