Title: tires on AWD car
Post by: TiNi on February 11, 2012, 08:24:52 AM
picked up a nail in one of my tires on the a4  >:(
tire guy says it can't be fixed because of it's location

good news is i have road hazard replacement on the tires,
but he also said he can't replace just one because the other 3 tires have 20K on them
...he wants me to buy 4 new tires!
i just got these last winter...

is this a scam or what?

You could get just two tires but then you'd be limited with the rotations (i.e. rotating just the two front w/each other and just the two back w/each other - as opposed to a full rotate that I try to do every other rotation:  left front gets swapped w/right rear, etc.). 

But I'm just a girl and that's all I know.   ;)

Damn nails.   [thumbsdown]

There is a possibility to damage the center differential of an all wheel drive car by running dissimilar diameter tires. They will tell you to not even replace two at a time as in both front tires but not the rear tires. Places like TireRack can actually shave tires down to the correct diameter to match you existing tires.

So the real answer is that it depends on how much wear the other three have gone through. At 20,000 miles the tires are most likely half way through their life cycle (assuming that they are all season). Since you most likely have road hazard warranties on all 4, I would push the place to replace all 4 tires.

I don't think there's much pushing on Tini's end.      ;)

Borderline scam, AWD likes having tires of equal traction and circumference.  As the tire wears the circumference gets smaller.  This throws off ABS and traction control too, since the smaller tire turns faster.  You have an A4, correct?  If so, you have a Torsen differential so there will be no mechanical damage like can happen on other systems.  Different specs for different cars.  Tread depth is the deciding factor. Most Audis allow a maximum difference of of 1/8'' tread depth between tires.  Your owner's manual should say something about this.  Another option is to have the new tire shaved down to the depth of the other three.  If no one local can do this, Tire Rack   http://www.tirerak.com (http://www.tirerak.com)   can provide you with a shaved tire for an additional charge.

Someone beat me to the punch, but Tire Rack can help you out. You have to pay for shipping, but the cost is nominal.

And by all means, ask what good the hazard warranty is.  It would probably help your cause tremendously if you paraphrased everything Howie said to impress the bejesus of your semi-scamming tire guy

The question should be why it was purchased, not what good it is.  ;)

1) COMPLAIN REALLY LOUD when they shop is full of other customers about the worth of the road hazard warranty. try and get the tire shop to give you a prorated price on ALL the replacements.

2) if that fails, try and get them to refund you the useless road hazard warranty. again, be VERY LOUD about it when their store is full of other customers.

3) then i would go with Howie's suggestion.

I've had 3 Audi's - A4 oil burner, S4 and now S3.  Had both the A4's leased and they only replaced 1 tyre in  similar instances.  Absolutely no difference I or Audi (at service time) could tell and I drove the two leased 4's pretty hard.

You'll more than likely find your tire on here: http://www.bestusedtires.com/ (http://www.bestusedtires.com/)

They should have more than one tire and in different tread depths.  I've bought multiple tires from this place.  Cheap tires and shipping and they last. 

BTW, A4 owner here, needing to buy 4 at once because one is shot is a load of crap.
