I need some assistance. i lost the formula u gave me on how to calculate the tire size difference verus miles traveled.

i went from 235/85/16s to 315/75/15s on my F-350 and wanna figure out the different. u did the same for my g/fs Ranger Edge when she went from stock 245/70/16s to 285/75/16s and it came out to multipling the miles traveled by 1.084. id like to know how to figure that out.

 

Try THIS. It's a pretty good conversion chart.

 

that site makes my computer freeze up, i tried it when i google searched :(
