Lol not at this place, just to give you a idea of how bad it is....the boss does it to. They are just that bad at math or whatever the explanation may be...i dont know. Its just a old, frequented by the same people bar.

 

would 225/45/18 be a good size?

 

If you run those tires compared to stock you are looking at this: 1.22"taller overall diameter, 1.18" wider, and the sidewall of thetire will be 4" highand if you are going 65MPH on your speed-o then you will actually be going about 68.2.
