I want a new set of wheels. What is the stud pattern and offset, and how large can I go?
The stock wheels have a stud pattern of 5×114.3 and the offset is +35mm. The largest that you can go on the Aurion without further modification or difficulty in finding load rated tires (load rating of 93 or higher), is 20 inches. A few members here have gone for 20 inches with no worries. That is with stock height though. Once you lower your Aurion, you may possibly get some scrubbing. Further information on this is further down. There is a website (http://www.1010tires.com/tiresizecalculator.asp) as well that is very useful in making sure your selected tire size gets as close to the stock rolling circumference as you can.
