Audi Rocks

Another update from me.
Have been regularly checking the tyre pressures and just replaced the rears after 24,000 miles. The NSR was worn down to nothing on the inside edge of the tread - as per the fronts! (see photo)
The front NS tyre which I replaced 10,000 miles ago is again wearing excessively on the inside edge. (see photo)
The rest of the tread on this tyre is in excellent condition as I would expect from a tyre after 10k.
Audi checked the alignment on all 4 wheels at 14,750 but reported it was near to normal.
I am still baffled why the inside of the treads should wear excessively to the point of bursting if not caught in time. To do this on the rear as well is really confusing.
Is there an underlying problem with tyre wear on the RS5?
The car drives like a dream and I cannot fault it other than this issue.

In my opinion, there is no excessive tire wear judging from your post. All car companies of today equips their halo cars with tires that are made with very soft compounds to improve their handling. Adding to that the power these cars are putting down, 10K miles per set is relatively fair. IIRC, one of the worst offenders is back when the Acura NSX was first introduced in 1990, their tires would only last 5K miles or so on average. However, you never mentioned if you had rotated the tires or not in your post, if not, you should consider doing that once every 5K miles and that may give you a little more thread life.

Needless to say, one also must keep in mind that tire wear depends largely on location (hot vs. cool weather), road condition (abrasiveness of type of road surface in your area) and driving style. If thread life and cost of replacement is a real concern with you, you may want to down grade from these ultra or maxium performance tires to HP all-seasons or tires with better thread wear (If you are not familiar with tires, look at the tire wear index, the lower the number, the softer and quicker they will wear out). If you do, do be aware that you will be giving up some performance for thread life.

Check out these puppies. Shocked to discover this. No idea of this until I took it in for a routine tyre change cos one tyre was losing pressure.

The mystery continues. No one can explain the huge difference in wear between the inside and outside of the tires! Why is it only S5 and RS5's that exhibit this issue?

Not my experience. I had a '99 A4 and put 150,000 miles on it. And it ate tires - mostly from uneven wear as portrayed above. Then I put 254,000 miles on an '01 S4. Ate tires too. Now I have an '09 S5 and it does the same.
I spoke to my Audi tech about it and he said that it is not just an Audi thing but an all wheel drive thing. He tells his customes to take the estimated tire life according to the manufacturer and cut it in half. Sounds about right to me. It is aggravating to see one side of the tire dead and the other with loads of tread life left. I just accept it as the price of admission.

That makes sence actually. My RS5 has only done 13000 miles from brand new and yet look at the state of those tyres. You would expect to get at least 25000 miles out of a set of tyres. I haven't even taken the car on a track or raced around too hard.

Uneven tire wear like the photos above has NOT been my experience with my last 4 Audis... I guess it could have been less noticeable as I rotate my tires and switch between a winter & summer set each year. However, when the tires have been worn out, they have never looked like that!

the inner tread on my 997 C4S wore significantly more than the outter tread and to a lesser extent on my B7 RS4. my assumption is to expect a wheel set up that promotes this uneven wear as part of the design of a "track ready" car. pehraps moreso with AWD?

I'm 3 weeks and 3k km's on my RS5 and will monitor and report back....

Same here on my 2012 S5 (sold at 25k) and now my 2013 RS5. 4500 miles on a set of Blizzak's and no visible wear. Summer Proxes going on this weekend.

I don't think it is a fault in the design. I had a c5 Corvette and it had the same issue, the inside of the tire wears out and the outside almost new. It is the wheels camber same principle like the F1 cars..
