I am asking about 285/25 R20's because according to this ( diameter calculator it's the size of tire/rim the most closely matches the stock 18 setup (only a 2% difference). I'd like to make sure that DSC continues to work.
Go by actual specs of the tires you are considering, not a generic calculator. As you can see by my examples, other sizes are closer in PS2s. The best piece of data to look at in this regard is the revs/mile, which compares circumference.
