Michelin Pilot Sport PS2 ZP

I read a lot of reviews which is why I ended up with the MIchelins, I'm wondering if getting rid of the Bridgestones on the back would help.

Fozzstar where did you get event tyres to visit to fit tyres, I noticed your in Bath which is where I work but checking their website they don't cover either this postcode or my me postode.

Just wanted to reinforce other people's views that the Michelins are far better than the OEM Bridgestones.

I own an E89 3.5i Z4 and have just replaced the Bridgestone Potenza runflats with Michelin runflats. I felt the Bridgestone RE050As were noisy, and had a tendency to tramline. Dry grip was excellent, but they were poor in the wet.

After some online research, Michelin runflats appeared better (quieter, better wet grip) so I had these fitted by Event Tyres (also chosen after much research - I didn't want my alloys damaged!). The result is great - the car is much quieter, grip in the wet is better, and it doesn't tramline.

Unfortunately the Michelin tyres are more expensive than the Bridgestones, but I guess you get what you pay for.

I had the following tyre sizes fitted - Michelin Pilot Sport 2 Zero Pressure (ie, runflat):
FRONT: 225 40 R18 88W
REAR: 255 35 R18 90W

Me to on E85 replaced original Bridgestones with PS2 ZP a total transformation as you describe ,certainly expensive but .................I am happy staying with run flats

Hi, I work in Chippenham and Event Tyres cover this area. So I got them fitted at work.

I would agree they are expensive - but in my experience they lasted twice as many miles between changes so they actually worked out cheaper...

I guess that's possible but I don't understand why this started to happen when the tyres were changed? Surely it would be something that would get progressively worse?

Just googled wishbone bushes and it sounds like if these were worn it wouldn't get through an MOT. I only had the tyres changed a couple of weeks ago as it failed the MOT because the front left tyre was worn... So the car had only just been MOTd.
Not necessarily - my car passed the MOT with no problems two weeks before the dealer suggested the bushes were worn, second opinion confirmed it so I swapped them out. Only then did I notice the difference. It could be that you were expecting more from the change to the new tyres?

I'd certainly get them checked out if it were mine...

But if it was worn bushes causing the problem then surely it wouldn't have started on the day I had new tyres fitted.
guessing here, but maybe just changing the wheels upset the status quo of the worn bushes and thus highlighted the problem :?

my dealer actually checked the condition of mine for free for me, can't hurt?
 
daviddi: Just dropped mine down to 27psi (fronts only) last night so will see how that works out.

gannet: Yes I can see what you're saying but it just seems too much of a coincidence to me. Unfortunately I have never been to impressed with the local BMW dealer here (Wellsway BMW) and very much doubt the word free is in their vocabulary. Both times my car had been to them they seem to have run out of time and only done half what they were supposed to.
 
Car has now been into BMW who can find nothing wrong with it, well they thought 27psi was too low for the fronts so have put more air in. I think the only thing I can try now is different tyres, I guess ditching the Michelins and going back to Bridgestones. Im getting concerned this could end up being something thats not going to get resolved and is going to end up costing a lot of money. Its seriously ruining any enjoyment of driving it though.
 
After going round in (expensive) circles with this I took the car into ProTyre in Bristol, one of their technicians diagnose this withing a couple of minutes as worn control arm bushes which they changed and everything is now back to normal. Currently very annoyed with Wellsway BMW for missing this, although on their paperwork they did provide a quote to replace the bushes when they called me to collect the car I was advised they had another 20,000 miles in them and didn't need doing. The final note on their invoice states the problem is a characteristic of the tyres.
