So, here's my story, hopefully someone can steer me in the right direction... About a month ago I bought new Kumho Ecsta SPT's for my e60, which was probably a mistake, but had to do it for obvious financial reasons. I wanted the PS2's but could not afford them right now...

Anyway, I am now getting a vibration that I can not get rid of, I have road forced these tires about 3 times and every time I road force the tires the car seems to be fine for about 1 day and then vibration comes back. I am beginning to believe that these tires just don't cut it for the e60 and I am now at the point that I want to throw these tires away and get the PS2's. I already checked all the wheels, one rear wheel was bent, so I had it repaired, vibration improved but did not completely disappear. I feel the vibration around 65-75mph, under 65 the car is smooth as silk. Another thing that I am noticing is that when I accelerate aggressively I notice the vibration becomes more evident. I don't know if it's because these tires are hopping or if something else is going on. I took it to my local dealer and they said the suspension looks fine...

BTY, I have 50k miles and I have oem 166m wheels. I already did a warranty exchange on 3 of the 4 tires and problem is still there. I previously had the PS2's before putting on the Kumho's and I never felt this vibration with the PS2's. I do not recommend Kumho's at all on any BMW.

Anyone experience this before?
Sounds like you got a bad tire...even the best tire manufacturer's turn out a dud once in a while. Go back to the tire dealer and ask for an exchange.

Kumho Ecsta SPTs and no vibration problem. I'll get PS2s next time though.

I already did they replaced 3 out of the 4 tires. Unless it's my luck and that 1 tire that was not replaced is out of round. Which is not according to Road Force.

I know you stated that your suspension was checked but how? I had a vibration and it turned out that one of the shocks was leaking. After replacing it, vibration was gone.

Well according to my local BMW dealership, everything looked fine underneath the car. But a lot of times these BMW service departments are not exactly the most reliable techs for our e60's. Most of time we know more about the cars by driving them and reading these threads.

Which brings me to another issue that I have... Click on the link for the topic of mediocre service departments.

Bty, I have put about 15k miles on these Kumho tires since this post and now the tires make so much noise that it's unbearable. Also, when I brake I hear a very loud "whoom, whoom, whoom" until a complete stop.

Has anyone experienced this?

Actually what I am interested to know is what happens if you do nothing about the vibrations?

For daily city driving, its quite difficult to reach speeds in excess of 50m/hr and as such, the car would not vibrate and drive as smooth as silk. Its only when on highways or maybe weekend spirited driving that you experiece steering wheel vibrations at higher speeds. So if I were to drive daily below 50m/hr (which will not cause any or maybe very slight vibrations), then can I ignore the high speed vibrations and drive as per normal as if nothing has happened? I asked my mechanic whether there would be any "danger" in doing so, he said NOPE.

Anyone has any comments or opinions? I also have vibrations at speeds above 50m/hr and am sick of going back to balance and re-balance the rims....

When the car's not vibrating at lower speeds, I guess it's ok. But when driving faster and you're feeling vibration, it will cause excess stress to bushings and suspension parts. How much, I don't know...
