I didn't know he invented the radial tire, pretty amazing man.
He didn't, Michelin did in the 1950's. That bit of misinformation has been going around for a long time, WIKIPEDIA gives him credit for that with a link to the patent, the patent is not for a redial tire and it isn't even his patent, it's his son Arthur
John Savage. The patent is for a belted tire, but it is not a radial ply, look at the side wall fabric, it's woven and not radially strung where the side wall cords do no cross each other.
uspto.gov/patent=01203910 - It’s got woven side wall fabric, which is probably stiffer than modern bias ply tires where the cords layers just cross over each other at angles.
