Bias vs. Radial
Ok, I have only used Radial tires prior to this experience. I've had good luck with BFG and Goodyear MT's. They have never demonstrated any significantly bad road manners. Here is The problem. I recently got a set of Swampers, 32x9.50's, Bias construction. Everyone told me they would "flat spot" when they sat for awhile. Well, I didn't know "awhile" meant overnight! But, that I could have lived with. Around town they are fine, no real complaints, once they are round again. But I just took them onto the highway for the first time, and I was appalled. They are down right Dangerous above 55 mph. The car has become very Darty, and is swaying all over the road! Now, the previous tires were 31x10.50 Goodyear MT's, and none of this was any problem at all. ANY IDEAS???? Or do I just chuck the tires?????
