Yeah I agree, Mastercraft is junk even though it's part of the US Goodyear/Cooper company it's one of those "enjoy our $1 taco at Jack-in a box of a tire" kind of relationship.
Goodyear is the only American owned major tire company left, Cooper used to be the other one, luckily they are still American owned as they got merged into Goodyear recently.
You have Hoosier and Vogue but they are not your regular consumer tire company.
