That’s probably why some places sell the same exact tire with the same exact size/thread/rating have different prices…
I use to see some tires advertising an 80,000 mile tires. I thought this was ironic, because several most people think….”cool, I can keep my tires for 8+ years” I never keep my tires longer than 2-3 years tops. (thread usually goes faster for me)…And i check the manufacturing date too.

I drive very little now. 500 miles a month if that. I bought a new set of tires about 4 years ago and had to have them replaced because of “dry rot”. They only had maybe 15k miles on them. If you don’t drive a car the wheels degrade.
The place I bought the new tires at filled the tires with Nitrogen. Nitrogen is inert so the tire isn’t corroded by the oxygen in it which helps to mitigate the dry rot.
