I had the shake/shimmy/nibble since day 1...until yesterday. Spent numerous trips to dealership, they changed all 4 wheels and tires and still the shake, field engineer came out and said "normal"...basically gave me a big FU we aren't doing $hit about it. So I lived with it, it wasn't too bad. I even removed the rotor clips And never figured out what it was...then bought new wheels/tires about a week or 2 ago, still shook and had them road forced and still shook. At this point, after 3 sets of wheels tires, I figured it was something in the car and not a balance issue. Well after reading this thread, I read about the tire/wheel overinflation during shipping deal and checked all of min and they were each at 47psi!!!!! WTF!!! Anyway after let some air out, no shake/shimmy/nibble!!! Looks to have been a balance issue with the crappy stock pirellis...

Pirellis are square tires. After perusing enough forums from other car makes and manufacturers it became very clear to me that pirellis are probably the worst quality tire you can put on your car. Nothing but stories about square tires from them and shimmy after 40mph from everyone driving any kind of car. It's just beyond me how a road force balancer can't detect that though as I had my original set balanced 3 times and every time they were within spec even though they were square as bricks...

I'm new to this particular forum, having spent most of my time in the classics forum. I have a '68 coupe that I'm restoring. I'm here because I just bought a 2006 coupe. It was mint with only 53,000 miles. I took it for a test drive and loved it. Unfortunately, I didn't test drive it on the highway (stupid, right?). After buying it, I found that the steering wheel would shake at 60+. The tires looked new (Nankang). I had previously bought new wheels with Pirelli Nero tires from a newer Mustang (0 miles) off Ebay for the 68 but had yet to install them. Rather than try to re-balance the ones on the car, I swapped them out. The shake is gone.

While I've heard several people refer to Pirellis as square, I'm loving mine.
