Single tire replacement RS7?

[gta7]

Hey all one of my tires is leaking the dealer wants to replace under tire warranty.

Car has a little over 16,000 miles they say it’s on the boarder but ok just to replace the one tire?

Should I replace two at a time? What’s the protocol for Quattro cars?

As long as the rolling diameter is within 3-4% you're ok. Not sure what tires are at tread-wise, but if they are 8/32nds and a new one is 10/32nds, that is likely ok. Obviously, the closer it is, the better. I've done this on my allroad and it was fine. Stick the new tire on the rear if you go this route.

Tire Rack will shave a tire to the requested diameter for a price, and I've done this before. A local shop may be able to do that, for a fee. Need to see if the dealer can work with someone to do that.

It will be fine. If the rest of the tires were completely bald there still wouldn't be 3-4% change in rolling diameter. Using my S6's 255/35/20 is 27". If your tires had 8/32 less tread that's 1/4" x 2 = 1/2" difference for a total of 26.5". The difference would be ~1.85%.
