So go with 235-40-18 or 235-45-18 to be on safe side. I think that should do it...it seems like a small width size with 18. Does it look weird on the car? Anyone has any picture? Thanks

 

see above posts! to be safe 235... if yuo want to take a chnace, 245 and then return them if they rub.

No it looks fine in 235...

 

PPgoal sent you a message...plz respond. Any thoughts on Prelli P6 4 seasons tires?

Any special tire that works better on Audi 18 inch wheels? Thanks

 

IMHO, the P6 4 season is not a very good tire.The F1 AS in 18 inch is awesome, however, someone told me they might get noisey after wearing down a little. Mine are brand new. They are quiet and the handling is far superior to the P6s that were on the car previously.

 

Hiredgun,

What size tires do you have and what year is your A6? Thanks

 

I did a lot of research before deciding to go from summer tires to all season and it came down to the Goodyear F1 As or Potenza 960... They both provide great dry handling for AS tires. The goodyear remains quieter and has a stronger tire wall.
I bought the F1 AS in 245/40/18 as I had Khumos in 245 before but they were too big and rubbed all over so I returned them and had 235's installed instead, much better. The F1 As is a big suarish tire. Also a 8.5 wide rim will stretch it more, my rims are only 8 wide

 

I am wondering if 245 fits better on 06 model. I called Audi dealer and talked to someone in parts and they recommended 255-40-18. I know 235 will be perfect with no issues but I have 245 right nowthat works fine.

 

My A6 is a 2004 2.7T SLine. Tires are the Goodyear F1 AS size 235/40/18. The rims are 5-spoke wheels taken from a 2007 04 SLine and have a 43 offset. As has been stated, this tire is very square and leaves me with almost no clearance on the inside.

 

OKK...so no one had luck with 245...[sm=noooo.gif]

I think I'll take it from your experience and go with 235 too

 

How much of a difference does a 18x8 ET42compared to 18x8.5 ET45wheels will make on A6? Are there any concerns because 18x8.5 wheels are the same as the other one but $90 cheaper per wheel.

I dont want to go bigger size if it's going to cause some other problem. Thanks guys
