Just had two new tyres on my A3 and they balanced them with steel
weights, not lead as they are toxic and not allowed to be used any more
incase anyone eats their wheels!
Since then my ASR light flashes when I pull away and has to be turned
off and on in order for me to carry on driving.
Could the weights be affecting the ASR or worse still could it affect
my ABS when I need it most?!
My garage is looking into it, but this could help if they find nothing
and others too in the future.
First thought: this guy is nuts. Second thought, maybe not!
OK, so you can't use lead... This is 100% correct, there are numerous
instances of smaller children chewing wheels and ingesting the lead
weights. Shocking but true, I read it on the Internet...
Yes, it is *remotely* possible that they are affecting the traction
control especially if they are magnetized! Try to find a heavy metal
other than steel of the same weight and substitute these for your
steel weights. You can stick them on with double sided foam tape
(that's still legal where you are, I hope!) making sure the wheel is
clean first. (One thought on a weight material is stainless steel flat
bar stock). You'll need a scale to weight each weight so your
replacements are the same weight.
And what country now doesn't allow proper wheel weights? I'd like to
avoid that country if possible--I have a low tolerance for extremists!
No, your new tyres are slippy and need to bed in. Take it easy for a
while. Steel weights are standard these days (EU Directive). It meant I
couldn't have stick-on weights on my A3 with 15" wheels as they fouled
Took the family to Wales for the weekend so have covered over 500 miles
and it still occurs. It is indeed tight with the calipers, the mechanic
tried sticking one weight on the other and that would have fouled so he
had to stick them alongside each other. They're right in the cap
between the spokes as well, quite unsightly but they'll soon muddy up
to match the rest of the car!
I had an ABS light after changing wheel bearings. VAG system showed left front
with a low reading compared to the other three wheels until it reached ten mph.
Turned out that the ABS sensor had been bumped so that it had twisted about 15
degrees out spec. I twisted it back straight and the problem was fixed.
As others have said I'd still suspect soft compound, colder, wetter and
slightly icy surfaces. UK is one of the few places we all insist on
driving all year round on 'all season' tyres and to be fair they are
pretty hopeless at this time of year.
Have you changed brands of tyre at the same time, so you are also
judging the old tyres capabilities to the new tyre?
I'd suspect putting the backs on the front will prove more about the
tyre compound than the balancing weights. Might believe it was the
weights if the problem went away running the fronts with no weights.
Hmmm, maybe, but surely when the front wear quicker than the rears,
there would be that slight difference anyway.
My garage is also going along with the weights being the problem now
and is trying to get some of the old ones for me. Tyres have done over
a thousand miles now so definately not down to slipping. Funny thing
is it only does it for about the first few minutes after starting off.
I turn the ASR off then on again and it won't do it again even if I
pull to a complete stop and start off again. It's only when the engine
has been switched off. Perhaps the ECU for the ASR learns to ignore
certain repeated signals?
Are you sure it says *must*?
It probably says something like ideally all 4 tyres should be of
equal tread depth, or at least a maximum tread depth difference
front to rear of 4mm.
It probably also says you should ideally have the same type of
tyre (size, make and tread pattern), between front and rear, and
definitely in identical matched pairs on axles.
The ESP computer should re-calibrate itself, everytime you first
drive off from a cold start, in two stages, the first around
5mph, and the second stage at around 30mph (it could be 30kmh).
This really needs to be done on a straight flat road - could be
difficult if you live on a steep hill, or hairpin bend!
One of the other posters I think mentioned you need to *run-in*
new tyres - on the front - 100-200 miles, on the rear (of a front
wheel drive) 500-600 miles - to remove the releasing agent the
rubber is coated in when the tread is moulded during manufacture.
