need help on sizing

[gerdaland]

i was looking at a set of miro m02's and saw they offered a couple different sizes and wondered which to get and also what tire size to run. i have an 01 b5 s4, stock brakes and h&r coils, the sizes i saw were 18 x 8" or 8.5" et45 or 35. i do not like the stretched look at all, i was thinking the 18x8.5 w/ et45 on a 245/?/18 but will it rub? any help would be appreciated.

The proper fitment for your car would be 18x8.5 ET35 with a 225/40/18 tire to avoid rubbing issues on stock suspension.

+1, or you could run a 235/35R18 (with ET35) and take a chance that you may have to roll the fender lip or adjust ride height

would the same work for 19"?

Same goes for 19s except for obviously the tire sizes. If you were going to run 225/40/18 on a 18x8.5 +35 and wanted to switch to a 19x8.5 +35 then you would run a 225/35/19 so that you have roughly the same rolling diameter (or within 3%).

I'm looking for a good tire size, I have 2006 Audi A6 Avant the wheel setup I have is the MRR HR3 20x8.5 ET 35 my car is also lowered on H&R springs about 1.2" but I will be going lower in the future. I was thinking about going with a 255/30/20 but I think it may rub the 245/30/20 looks like a better option but I don't want to effect my ABS or brakes, would the size difference be that dramatic?

Sorry, no recommendations on 20" fitments... To get the correct load capacity (around 1,500 lbs per tire), everything we have would be way too wide or tall
