Hi forum! I'm new in forum, and I am trying to find rim sizes and stuff like that. Well, i have a Audi A4 avant 2003 (B6) and I currently wearing the stock 205/55/R16 with.. uh I dont really know the rims. So I want to go to a 18" wheel but I don't really know what search. For sure it will be the same diameter, so I do not lose a lot on speedometer. So you have any suggestions why I cant understand the difference from the 7Jx18 ET35 and the 8Jx18 ET40 for instance. I mean how thiw numbers affect the driving experience. Thank you, any suggestion much appreciated and sorry for my English.

Should not be that different but running wider tires will cause you to use lower profile tires to make the outside diameter the same. This could make your ride harsher. Also the wheels and tires could make them heavier.
