So your saying.. I don't need any specific tires on the front and back so long as they fit staggered and are for 18's... I'm confused[&:]

 

You don't need "special" tires for your wheels. It's generally a good idea to have the same brand/model of tires all around. I also am noticing I left some other info out.

I'll put this in the simplest terms possible to spare you any confusion:

You have two choices for the "best" route to go for your tires:
225/40's and 255/35's
or
225/40's and 245/35

By "best" I mean these will look the best on the wheel (won't look like balloon tires, won't be too stretched, etc.), will offer you the best handling performance, and they will be properly matched as to not do any harm to your drivetrain.

HOWEVER, if you would like to run the 265's in the back since you already have them, you aren't going to hurt anything on your car. Get the wheels, put the tires on them and drive the car. Once you lower your car, you may have some rubbing issues in the rear though with all that tire back there.

 

what brakes are those?

 

In the first pic? Stock 1.8T brakes painted red with a white Audi sticker on them.

 

Alright, thanks a ton cap'n.

You got my confused mind on the straight and narrow

 

i wouldnt run staggered. get a nice lip on all 4, that looks sweet enough if you ask me. but if you must do staggered just make sure you do it correctly.

 

If you want to run a staggered setup, the diameter of each of the wheels must be the same, meaning the sidewalls have to be all equal. If they are even a little off, the tires will rotate at different speeds, thus impacting your center diff. I believe the diff only has a tolerance of 3%, so be careful with tire sizing if you don't want to fry it. I do not know a great deal about tire sizing, but I think you would want to run both tires with 40 so the sidewall will be the same. It's going to be a pain, but just make sure the rolling diameter is equal all around.

 

Well like Captain Obvious already pointed out... it is entirely safe to do it if you match up the sizes properly.
You can definitely run a 265/35/18 rear and 235/40/18 up front... that would keep you at the same diameter as the stock 235/45/17 I believe.
Anyways, I've got 255/35/18 on the rear of my B5, and I'm lowered on coilovers fairly low. B6's have a hell of a lot more fender room, so you'd definitely be fine with a 265 back there. It's what I'd do if I had a b6. Only, I'd get 10" wide rear wheels, and I'd not use the HP Evo (again, repeating what he said).

I used to like the HP Evo's too... but the look slowly wore off, and now I don't even like them.

 

=\!

 

Don't worry about what we think about the wheels... it's your car not ours. If you like them, get them. Lots of people don't like my wheels, and I could care less because I love them.

Remember the old adage: opinions are like ********, everybody has one.
