I had to replace all 4 tyres on my Boxster a couple of years ago in Cannes after taking part in the Grand Tour.
The Porsche specialist there obviously did not balance the wheels because as soon as I hit the about 70 on the peage the steering began to vibrate. He tried to tell me it was because the tyres were new and it took a bit of argument and a return visit for him to take me to the guy who fitted the tyres in the first place.
And I had to take Continentals as there were no replacements available for my preferred P Zeros.
Incidentally, does anybody else think that considering the level of personalisation available from Porsche that it' s a bit rich that you have to take whatever tyres they choose to fit on a new car?

Helen' s problem is most likely to be wheel balancing. Either they have worn enough for it to become noticeable, or a weight has fallen off.
It' s pretty quick and cheap to find out.
I was a little surprised that I didn' t have a choice of tyre brand for the car. They don' t have an exlcusive deal since the various 911 models come with different makes, some are Pirelli, somce Continental. I think both firms do tyres with suitable specs.
Yokohama wasn' t an option.

Jasmin have just told me the tracking is out which has worn the inside of the tyres?????
i' ve had tracking problems with a fiat coupe i' ve owned before and it was really noticable, made the car a real handful to drive. can' t say i' ve noticed any handling trouble with the boxster. have i just been conned into a set of front tyres!!

No there is no con. If you are concerned get them to show you the ones they took off.
If the tracking is out, a new set of tyres can wear to the point of being illegal in only a few thousand miles, <5000.
If is toes in too much, you will wear the outside edges of the tyres.
If it toes out too much, you will wear the inside edges.
Both will cause increased fuel consumption, lower top speeds, and less ease in coasting, i.e. it will feel like there is more engine braking than normal.
You may find it is more fidgety at speed, with directional stability affected requiring more steering adjustments. Camber changes and ruts will make this more pronounced.
It depends on how far it is out.
Kerbing, pot holes, and dry steering (turning the steering wheel while stationary) are the most common causes, along with just wear and tear.
With large tyres you put a lot of force into truning them when stationary, hence the reason for having power steering, but it masks the force you put in. I always try to make sure I am moving when steering, you only just need to be moving. (A result of owning a Golf when they used to not have power steering).
You should check the tyres regularly, to look for uneven wear. There are normally two locking nuts on the steering track rods that get adjusted. You need the correct alignment equipment, but the procedure is quite straight forward.

i had noticed power lose but put that down to expecting too much after driving a GT3.
Larry takes wheels off sometimes to clean he hadn' t noticed any unusal wear.but it must be a couple of months since he last looked.
