Ahh ok, so I need to see a tire specialist and give him this option that, all 4 should be the same size since I tried to lock the front tires all the way in and out and I couldn't tell if there will be more room for 285s, tho it looked like it will but my untrained eyes can cost me a fortune.

Do you suggest moving to 20" btw or 19" would be fine? I am going for a bit of an aggressive look as well as some performance.
