Interesting, so I could run 4x 245/40/19's on my 19x8 wheels? or that may impact my speedometer too much?
here's a link I found that ( answered my question above) shows how changing the stock tire sizes affect the speedometer, diameter, revs per mile etc. Pretty nifty calculator which has helped me decided that 235 is the ideal size I need for my purpose.
