Hi
I have A4 1.8 Avant 1998 B5

Want to put 18" wheels on, but dont know what type of specifications i need.
Offset: ?
Stud Diameter: ?
Rim Width: ?
Rim Diameter: 18"
Anything els ?
Thanks for your time
Doj

 

offset is +35
stud diameter (i assume you mean bolt pattern) is 5x112
rim width should be 8" inch since most 18" wheels are 18x8

 

i have the similar one
mine are
5x112
35 offset
18x8


But for tires :
tires i have on my r8 replica are Firestone Firehawk Oval Wide Indy 500 , and they are 235/40/ZR18

 

Just found these on ebay, for what i thinks a good price
Audi rs6 style alloys and tyres 18 inch
Rim Width: 8.5J
Rim Diameter: 18 inches
Offset: 40
Stud Diameter: 112
Sorry to be so dumb, but i guess these are no good for my car then as the rim width is 8.5j and off set is 40
Or am i wroung,,, lol
Thanks again
