I love this forum, and I think it helps a lot, so it's time to give back to the community. I believe I read in one of the threads that someone is running 245/40/18 in the front and that's almost the same as stock size, which made me check it and let me to believe not everyone is aware of the site below. It is very useful tire size calculator, and everyone should have this in their favorites. Just type in your original tire size, followed by all other sizes you think might work or be similar and click the botton below.
For example type in:
225/45/18
245/40/18
255/40/18
then click Compute Sizes and it will show you that the latest one is the way to go when upsizing your front tires if you have 18s.

Hope this helps some of us. Good luck, enjoy and be safe.
