With stock tires you get a true reading on your speedo and true MPG calculations. So, if you get larger than stock tires your speedo reading will actually be less and your mileage less? right? So if you are running 31's for example and a 50mph reading is actually 55mph, your mileage calculation will be lower than it actually is; about 10%, right? I was just curious, it doesn't really matter, it's all good fun anyway!
In a way it does matter. If you are tracking your mileage for reimbursement is one example. 35 cents a mile can add up quick. I may have lost $600 to $1000 by not adjusting my mileage for the incorrect readings. Enough to buy me a lift kit.
"Reimbursement is one example." Very true. Another is, "Officer, you mean you're going to give me a ticket for ONLY 5 miles over the speed limit? How Chi---- Sh--." "Well, no.....11 miles over the speed limit, smile, smile, gotcha, smile, smile!!!"
My bad on the keyboard. /wwwthreads_images/icons/frown.gif I should have said 32 cents a mile. And Hey, it was Carolina Power and Light, And I don't work there no more! /wwwthreads_images/icons/laugh.gif
I'm running 31's and I'm about 5mph less than actual; tested by driving side by side with my wife and telling her to give me the 5 - 5 sign when we get there. Due to recent technical advances we now calibrate via cell phone. It's been rare that I've ever owned any vehicle with true readings. So on my Jeep when it calculates to 12.8 mpg it's really about 14.08
