Mmmmm, shame I have to post this. After initially thinking I'd got a good deal, it is apparently NOT the case. Now had the wheels/tyres for just over 2 weeks. Had them put on and instantly felt vibration and movement to left and right through steering wheel which shook violently at speeds over 60mph! Thought it was road camber or they needed 'bedding in' for a few hundred miles. Vibration through accelerator pedal and judder on steering wheel if I braked or sped up to 70mph plus! Assured when bought that they were in perfect condition AND balanced correctly. NOT THE CASE. I finally took the car to my local ATS today and the news was not good. All 4 wheels were re balanced and ALL were well out! Old weights removed and replaced/balanced properly. EVERY wheel was wrongly balanced by a very wide margin. I was also informed that it was HIGHLY likely that the nearside front wheel was buckled! I was told by the seller that he ran 32psi in the fronts and 35psi in the rears. When checked, 27 in the fronts, 30 in offside rear and 28 in nearside! You are a Z4 Forum Member and I expected better. :thumbsdown: :thumbsdown:
Apologies for taking so long to reply to this, there are a number of reasons for this, but I don't think sharing them will help in anyway.
First and foremost, I can only apologise for the experience you have had. I can hand on my heart say that I did not know of any of these issues, and am completely baffled how from taking a set of wheels off my car (which i did myself) to putting them into my parents garage, to finding their way onto your car, that all these issues somehow came about. I can say without a shadow of doubt that the wheels ran perfectly true, and I would rather not admit any particular speeds on this forum, but say that I never had any balancing issues at any speed whatsoever.
Can I ask who fitted the wheels to your car? Im just curious to know whether the vibration could be explained by a loose wheel ? I've never personally experienced this, but after reading your message, I spoke to a mechanic friend, and the tyre fitters who balanced your wheels, and both said that wheels which weren't tightened correctly could have been the original cause. They also said that over a period of time, any wheel could work itself out of balance due to potholes etc so it could explain partly what went wrong ?
With regards the difference in tyre pressures, a small amount (about 3psi) could be explained by the difference in ambient temperatures. As the colder weather comes in, the temperature drops, as does the pressures. The weather has been warm until recent, so last time i checked, they could have been correct, but again things have changed.
Not sure how to resolve the issue, besides offer to at least cover the cost of the balancing. I know this doesn't resolve the issue entirely, but not sure how this has happened. Surely you could tell the type of individual I am, from the way the wheels were safely stored, with card and bubble wrap, and the way i handled them carefully and placed them into your car, and the condition of them. The wheels have only been near my wheel brace, which has been carefully placed not to mark the wheel area surrounding the bolt, and always tightened by torque wrench, no air tools ever. Somehow I doubt ATS would have given the same care and consideration I have to the wheels. Did you actually see the wheel on the machine show an imbalance? Sorry to ask, but this is the same ATS chain that fitted a tyre marked inside the wrong way around on an alloy for me, only to say that it wasn't an issue and I could simply swap it to the other side !! The same ATS chain that replaced all 4 tyres on my wife Audi TT some years ago, saying it was 4WD and it would have problems. On my return, I took the car back to them and pointed out that the car was in fact a 2WD model, and that the tyres they took off had over 5mm still on them, so I wanted them back ! So forgive me for not trusting what they claim, but experience teaches you everything.
Not sure what else to say. The whole situation has left me genuinely upset, so I can only imagine how annoyed you must be feeling.
Speak to my friends, even my neighbours, and I hope they would say how honest and helpful a person I am.
imo they sit & suit your coupe far better than the Tyrus do
