Tire sizing odometer modifier?

[BuggyMeister]

Adding a percentage modifier to odometer readings automatically. Could an option be added to the vehicle profile to add or subtract a certain percentage of miles during the fuel up?

I would like revisit BDC's July 19, 2009 suggestion of adding a percentage modifier to odometer readings automatically. My truck has bigger diameter tires than then it was sold with stock. In my case the odometer shows that I went 7% less distance than I actually did. When I add a fuel up I have to first calculate the correct mileage then go to the web site to add. This feature would automatically add or subtract X% to the mileage when doing a fuel up. Many users would just leave this blank and their mileage would be calculated without modification.
