As the wheels are 5x112, I am talking about MK5 on which the standard Zolders and Omanyts are ET51The guru makes a mistake! Aristos are ET38...
No, they'll stick out one J (25mm/1inch) + 20mm = 45mm moreAs they are 8.5J wide and ET31 it means they will stick out 33mm compared to the standard 7.5J ET51 wheel. Not sure how much clearance there is before you start rubbing on the arch.
Although the wheel is an extra inch wider, only half of that extra width affects the outside rim, half goes on the inside rim as tbe offset is measured from the wheel centre.. 20mm due to offset plus 13mm due to extra width.No, they'll stick out one J (25mm/1inch) + 20mm = 45mm more
