Slipping all over the place

It's not been icy recently, in fact it's been about 6 or 7 degrees C and quite dry. But for some reason my back end keeps slipping out if i accelerate too hard from a junction.

Obviously it's worse if I turn the traction control off. But I don't recall this in the summer at all, I could be failry heavy footed anywhere and not experience this slipping.

Does anyone else experience this ? Maybe the roads are just greasy with dirt and old salt etc.

The Z4 is my first rear wheel drive car.
 
Look OK to me. They were new on shortly before I bought it off my brother in law in May.

Or did you mean tyre pressure ?
 
I've been having exactly the same problem. Was starting to wonder if my right foot was getting heavier.

Must check my tire pressures, the tread seems fine.

Run flats yes..but they always have been.

Could tyre pressure have an effect,..I thought low pressure caused other issues like uneven tyre wear and bad fuel consumption...but slipping ?
 
Funny you should mention that I had same issue tonight. Guess I better check the pressures tomorrow. As an aside driving down the a19 tonight I heard a massive 'pop' noise like when a tyre is inflated slightly at the garage to fit it to the rim. It's fair to say I needed new pants! Upon inspection all seems fair with my zed though :)
 
If you have the performance summer tire fitted they do not do well when temps drop down near freezing. It is usually suggested to switch to a winter tire when temps are running around 5 C or colder. Loss of traction on even dry pavement is the result and is very noticeable.

OK thanks,..but it's not icy right now...this is why I don't understand it.
 
If its like where I am in Sussex the roads are greasy as anything, so combined with poor tyre temperatures its easy to see why they break grip I think.
 
I've found this too in the last few weeks since the roads were heavily salted. I'm using correctly inflated Vreds.
I agree with the above, it's a combination of greasy roads and cold tyres, without even consideration the frost and ice.
 
I find the bridgestone RE050A RFT's seem to go from decent in summer to craptastic at lower temperatures, probably the rubber compound and the lack of flex in the tyre.

They were very slippery wed morning around chailey, even my old pug felt unattached to the road
 
Rubber goes off with cold.
Sure it's something like 7 degrees when standard tyre performance drops right off.
I recently chucked 4 continental winter tyres on the van - fantastic modification.
When getting back in the z4 - it's like bambi on ice.
 
from a recent Goodyear press release

December 28, 2010 – Goodyear wants to ensure that all truck, bus and coach operators who have vehicles operating on German roads, including transit traffic, are aware of current new tire safety regulations. These cover all trucks over 3.5 tonnes and buses with more than eight seats operating in winter conditions on German roads. Such vehicles now must have M+S marked tires on their drive axles or their drivers face penalties.
The change to German traffic regulations came into force on December 4 and covers conditions where a road is covered with hard-packed snow, ice or slush. In these conditions M+S marked tires must be fitted to drive axles. Failure to do so will result in fines and driver penalty points.
All current Goodyear drive axle tires available in Europe for such vehicles are M+S marked but drivers and operators should check other brands to ensure they are not only legal but safe, and that tread depth is sufficient. Goodyear recommends a minimum of 6mm tread depth in these conditions unless local regulations state otherwise.

Bedales corner on the Scaynes Hill road is very nasty as well, plus the road down to Lindfield as there are so many pot holes on that stretch
 
Good to see it's not just me. My guess is greasy roads due to recent salting. Maybe we need a good amount of rain to sort it. I'm glad I've had my warnings while the traction control has been on though...
