Yes those thing make a difference too. To me the biggest thing is air.
You almost never see a radial tire wear out in the middle from over inflation. ONly the edges first because of under inflation. A tire that is low on air can not disapate the heat properly.
The video is about selling tires that have been sitting on a shelf for many years. Basically tells people to look at the tires they buy.
Don't except a 6 year old new tire.
I work at a gm dealership.
Sold tires at Monkey Wards and two dealers.
Grew up in a gas station back in the late 1890's. Tires were different back then though. Made from wood. lol
