I'll second that comment by Swampler. I had the same problem with the Coopers on my F-150. I too bought them for the cost savings and I also bought the BS that came with it. When I took my Ford to the dealer because of vibrations at highway speeds, he told me flat out it was the tires. I didn't believe him then since they were less than a year old. A second opinion changed my mind. Won't be fooled again!swampler said:I've never been impressed with Goodyear tires. The ones that came on my F150 were junk and wore out quickly. I replaced them with Michelins (in fact, they were LTX M/S just like on the RL) and were great. When they wore out, over 50k miles later, I replaced them with Coopers because of cost and I knew I was wanting an RL soon. They were junk...Lots of road noise and vibration.
