For the most part, I haven't had any vibration problems with any of the brands of tires that I have bought. The vibration problems that I have had come from a wheel problem, balancing problem, or mismatched radials on the same end of the car. The most baffling problem was when I bought an off brand tire to replace one of a set of Delta Durasteel's (another extinct brand of Wide White Wall Radial). I had let a tire go flat on a car that was in storage, and when I re-inflated it, and drove the car, the tire ruptured. The brand was no longer available so the tire store sold me a similar tire called Peerless (yet another defunct brand of wide white wall) but it had a different tread design. When it was on the front of the car it made the whole car shake at various speeds, even though it was in balance and did not have any internal damage. I finally bought a second Peerless Tire and put it on the front also so the each of the front tires matched each other (the same with those in the rear, which were still Delta Durasteels), and the vibration went away. There is no end to the fascinating stories that we can tell about tire adventures. What an interesting thread!
