Tires OEM Audi or Continental

M3 Non Snow: BFGoodrich gForce Comp 2...M3 Snow: Continental WinterContact Si (very, very happy with these over years of being a Blizzak driver)...Wagon Non Snow: Continental ExtremeContact DWS (very happy so far)

The DWS06 has been a phenomenal all season tire for me...These Contis have proven well worth it, as even with a FWD car, I'm able to drive on snow with minimal slippage.

Continental ExtremeContact Sport, 225/40/18

These are the tires this car should have come with from the factory. They are smoother, quieter, and (obviously) grippier than the OEM A/S tires in dry and wet conditions.

Got mine at America's Tire for 800. Best tires I ever owned!

The Michelin Pilot Sports A/S2 are the best tires you can buy for these besides Pirelli. I just put Continental DWS06 tires on my 2016 6 and it was like driving a different car. So much smoother and more responsive.

Not on your list but the best all season is the continental dws.

Well balanced and smooth at any speed. Tires are in great shape with almost new thread depth.

I have a set of the new Continental extremecontact sport ready to throw on very soon. These tires were designed to compete with the new Michelin summer tires. Tirerack did a performance test on the top summer tires and they performed just under the new Michelin PS4S but for way cheaper.

Most people conclude that Grand Prix are the best mix of puncture resistance, weight, grip and speed to sort of be the industry standard.

I rotate tires every 5k to keep even wear and am no longer a fan of Toyos ... Anyway, I'm hard on my car (ie: drive it like you stole it) and even with a track day under my belt, I'm doing better than 8-10k miles on my set of Contis although don't get more than 2 seasons out of summers (approx. 15k miles).
