265 to 315 tire calculation needed

My truck came with 265's. I am running 315's now. I am getting 500 miles per tank on the OD. What do I multiply my miliage by?

The 315's are roughly 10% bigger than the 265's so what ever your trip reads add 10% to that and divide by gallons of fuel.

Why not just get your CPU reflashed at the dealer? Then you would have the correct Odometer and Speedometer readings.
