I have an edge evolution with custom tunes from php. I had them written with 275/55R20 tires. I'm having 305/55R20's installed and at the moment when I go to "correct" the tire size it says the current size is 2499.... So I have no idea what my new size should be? Any ideas anyone? I thought I would just put in the new size or the standard equivalent but now I'm not sure.

Never mind I used the lovely search feature and figured it out! Technology is great when you use it.
