KS was acquired by Goodyear at some point and now claims to be Goodyear's "budget" brand. I bought a set a couple years ago for one of my beaters.... No complaints here and the price was right. They were made in USA which I assumed to be at KS's Freeport IL plant but I noticed recently that plant now makes tractor tires for Goodyear... So more likely mine came from Tennessee.I saw the signs for them at PepBoys the other day BUT haven't seen them on any cars in a long time - Kelly Springfield (owned by Goodyear). When I was young I saw them often on cars and trucks, now?
And yeah..... Sumitomo is widely known.
