Vibration and Wearing out Lexus LS400
They had an initial imbalance that could not be cured. I've replaced the front components on the car and still have a vibe I can't get rid of. They are also wearing out quickly.
I like my other Cooper(Discoverer AT3 for Tahoe) tires but not these. They seem to get worse as they warm up. In reading about their construction I found they use a unique method that changes as the temperature of the tire changes. I think this may be where the problems originate. Now I've found out that Cooper discontinued them......
Quote from Cooper:
"The CS4 is the first tire designed using Cooper's new R-Tech (Response Technology) construction. R-Tech's features include strategically placed, variable density nylon belts designed to minimize flat spotting and maximize even tread wear and a special nylon wrap that shrinks under heat to improve rigidity and dry traction. The tread design also features a wide tread arch, an open shoulder design, and wide grooves aimed at improving wet traction.."

Even though they spent a fortune and millions of miles testing something seems to have gone wrong.
I'd like an explanation from Cooper and a discount on another set of tires!!
