20" stagger Quattro help. Wider up front?
Right now I have 20x7.5 245/35/20 all around.
however last night I hit a curb and destroyed one.
so now I’m looking at getting just two 20x8.5 and putting them upfront
what would be the best tire for it

Make sure the tire you get matches the circumference of the tires in the back.

I think he means the tire and wheel, regardless of the width, must be the same size on the outside circumference as the remaining tires. With all wheel drive this could be very important I think from a mechanical as well as a control aspect. I'm also new to these cars but makes sense. I would question why you want wider wheels on the front though. I'm not aware of any benefit to having wider wheels up front. On my C7, the rear are considerably wider to put more rubber on the road for traction, but with all wheel drive, what's the reasoning?

upon doing slight research prior to posting, the A6 is known for its under steer and putting wider wheels on the back further exacerbate that issue, however putting the wider wheels upfront help counter act that.
however most people don’t like that look so they tend to stick with same size wheels all the way around or go with the rwd staggered look.
but for performance reasons, wider is better in the front.
which is better if I’m using the car in the track, which I’m not, however I’m a spirited driver so I’d rather not add more under steer and Id rather not buy a full new set of wheels because one is destroyed lol.
so when you say the same size…
how does that correlate in relation to the current tires which are 245/35r?

You will probably need a tyre wider that 245 for the 8.5 wheels in order to ensure the rotational distance (ie circumference of the combined wheel and tyre are the same for all wheels). This is because a 245 tyre on an 8.5" wide wheel will be flatter than it is on a 7.5" wide wheel. Whilst we are probably only talking small amounts of differences it will upset the differentials and gearbox big time if for every revolution of one wheel it is only doing 0.97 for another. This will cause stress and ultimately expensive failure of the drive train. It is why you should always change both tyres on a given axle unless there is going to be less than 2mm difference in depth tread between the new and existing
