Slipping all over the place

ferrelscent · Post by **ferrelscent** » Wed Jan 19, 2011 11:06 pm

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.

Checked the Tyres?

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.

Tyre presuures should be checked every 2 weeks

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.

Afraid so!

That sounds like way too much time and effort taken away from me cleaning and waxing my Zed!

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.
