You guys have all been so helpful. My car has Yokohama Avid H4s. I got them about a month ago for $90 a peice. They seem like a good tire, they hug the road fairly well when cornering and are a good compromise to ride/comfort.
Just now, I went on a 2 hour drive through Orange County to deliver paperwork (part of my job) to numerous offices. The steering wheel vibrated much less when doing 80 or 90, than at 60. Prior to going on my drive, I ordered a new steering damper. NOw that I am back, I decided I do not need one! The order has already been shipped, so I suppose I will keep it and change it anyway (??) or wait until something happens to my current one??
I believe the shocks on my car are the originals, and will probably be needing replacement fairly soon (15K + miles), and figure that might slightly improve it as well.
As for my spare, it is the original COntinental spare that came with the car (I believe...). Or did they come with Michellins in 1995 (actually 10-94)??
And no the tires were not balanced at an MB dealership, so I am sure that that could also be part of the problem.
Maybe my next tire will be Michellin MX4s?? For now, I will have to drive the life out of these Yokohamas.
I am guessing that there are many minute reasons as to why it vibrates. But like I said, it doesn't vibrate hardly at all above 80, all the way up to 120.
I entered the 405 FWY from another (55) FWY and there were NO CARS, this is SO CAL?! What was going on?? There was not a person in sight in front or behind me!!! So I floored it all the way up to 120 mph, I have NEVER gone that fast in my car! I just wanted to see how it handled. It was surely pushed a bit by crosswinds, but other than my knees shaking from nervousness, the car drove wonderfully! And NO wheel vibration. Seems like it only occurs between (roughly) 40 and 65/70 mph.
Thanks again all.
