I can't seem to figure out the math...
Okay y'all I am plain dumb I guess. I use an app on my phone that is like the fuely app. I just filled up tonight and the app said I got 14.5mpg. Now I know its not right due to me having larger tires. So I am asking how to calculate it right. Truck came with 265/75-16 tires. Currently has 37/13.50-17 tires. According to a converter it shows that the tire I have now is 59.2% larger. Seems a little large. But If you all could help me please I would be appreciative of it.
