I once bought tires with an "all road hazard" warranty, which was denied
Way back, many years ago, many, if not most, tire manufacturers included a "road hazard" warranty. For no more than we had to give warranty on, I think the manufacturers made a mistake when they quit doing that. I don't know whether
any tire manufacturer still provides a road hazard warranty, but some dealers do; some charge extra for it and some just include it.
Before the days of radial tires, I liked nylon tires because they usually held together and lasted longer.
However, when bias ply nylon tires were cold, they did have a flat spot on the bottom that would make for rough riding until they warmed up. The worst I had personally was my 1973 Winnebago Brave motorhome. I never had to replace or rebalance a tire on that motorhome, but every time we started out with the tires cold, we had the thump, thump, thump and dishes rattling in the cabinets for the first few miles.
I don't know how often tires of different brands cause a vehicle to pull one direction or the other, but it sure does happen. The first time I saw it was in 1991 in Anchorage when a customer brought in a new small, compact Pontiac for a front end alignment and the alignment checked out perfect to begin with. Sure enough it pulled hard to one side, we swapped the front tires and it pulled hard the other direction. We moved the front tires to the rear and rear to the front and cured the problem, even though we couldn't find a thing wrong with any of the tires.
Then I bought my current 2001 Ford Ranger in December, 2004. It had what appeared to be almost new radial tires, but a brand I'd never heard of and couldn't find anything, even on the Internet, about them. But it pulled to the right. I had a front alignment done that didn't change a thing, but a tire rotation fixed it. I've since replaced those tires with BFGoodrich Long Trail Radials.
In fact, I've been using BFGoodrich tires with good luck for several years, and it really doesn't have anything to do with the fact that my brothers used to be Goodrich dealers.
