Worn rear rear tyres and twitchy rear end

[Chris944]

HI Boxster fans,
My 2000 Boxster S seems very twitchy at the back when driving. The tyres are inflated okay and the wear is even across them, both front and rear. The rears are worm down to around the legal limit according to a non-Porsche specialist tyre shop, with wear at the front being fine. Can anyone offer advice on what's likely to be the cause of my twitchy-feeling rear end - mis-alignment, tyre wear or something else?
Cheers.... Chris.

So fully worn rear tyres then, and you're wondering why the back end feels twitchy?!

Get them changed before something bad happens. I tend to change mine when they hit 2.5mm, anything lower and the back end starts moving too much for my liking.

Thanks Ekona; that's nicely clear and crisp.

wrong tyres - the weather - the make of tyre (they are ALL different) - water on the road - oil on the road - your driving skills/style - suspension geo - blah blah blah!

I changed mine today, even excusing the fact that they've still got the release agent on the grip level is noticeably better, and that's only with a set of RE050As. It makes a nice change being able to get the power down for a change!

Greasy and cold road surfaces won't help matters either though.

A little tread always helps

Is this a wind up!?

Legal limit 1.6mm and they want to know why the car is not driving as it should, is it me or are people on another planet.

To be perfectly accurate "A little tread doesnt help at all!"

This may help the OP understand here

That was my first thought.

Words like complete, total and certainly spring to mind here.





In both spheres.

What tyres are you running ?

If you are running summer tyres during this time of year the back-end can twitch even on fresh rubber.

I ran PS2 summer tyres last year (on 19s) and it was an edgy experience in Dec/Jan. I sm on winter tyres this year, no twitching thus far.

I would say get fresh summer rubber fitted now and if you need to run it through winter next year, plan to swap them come Nov for some winter tyres.

Common sense and good video.

could be a multitude of things, I think more often than not it is the road conditions which catch people out

lots of people saying more tread needed, does this help in the dry?

[Ekona]

Err... yes. Tread helps all the time, although those tyres with very large treadblocks can feel a little unsettling at first if you're not used to them.

i thought the fastest tyre in the dry would be a slick tyre due to it providing the maximum contact area with the ground

Ops 2000 Porker S ... coming to a hedge near you! Courtesy of cold weather, summer tyres with no tread and a lack of stability control.
