Mileage difference?

How much will mileage drop just by changing from a stock sized road tire to a stock sized mud tire? I'm not looking for exact numbers, just an idea (1-2mpg)???
Thanks

Thank you for the post Shinny.

Mud tires typically have more rolling resistance and also weigh more which will affect the MPG. I would anticipate a 1-2 MPG change but it all depends on the Mud tire you go with.

Just swithed from Nitto All Terrains, to Toyo Mud Terrains, and haven't noticed a bit of difference. Stock sizes of course.

I changed from the stock 275/70-18 to Hankook Dynapro MT 325/70-18 which is the same diameter as the factory tire and lost 5-6 mpg due to the added rolling resistance.

I lost about 1 -2 mpg. Same size, same load range. I went from a Mesa AT on the bakc and Transfomer HT on the front, to the Wrangle Autority AT on all 6. These tires so far sound like a AT but have the looks of a MT. Not bad so far, but still lost about 1-2 MPG.

This is what I had, 235-85-16 LRE

Almost no difference at all. Most people forget to add in the added difference in tire size when computing mpg. I know when I went from 285/75/17(stock) to 35 inch mud tires i saw no difference and maybe even a little better mileage. But what you need to figure in is that those 35's are almost 10% larger than your stocks. So when your odometer says 400 miles you actually went 440 miles. On 24 gallons thats the difference of getting 16.6mpg or 18.3mpg. Thats a big difference. Plus with the larger tire size you'll actually have lower RPM's at cruising speed so that will help your mpg.

i dunno, a good buddy of mine has had a set of those on his f150 for about 2 years now and they still have about 50% tread left.. and his truck is a daily driver.

They're the same rim diameter, but the overall diameter is significantly bigger on the Hankook. The stockers are 33.1574803 in and the Hankooks are 35.9133858 in. Give or take a little bit.

It takes more energy to get the bigger, heavier tire moving so in town or on short trips it normally costs 1-2 mpgs, but on long highway trips you may actually pick up a 1 mpg
