I just put on a set of 20 inch wheels/tires on my durango. Now my gas mileage has dropped nearly 3 miles/gallon. The Durango is a 4.7L, all wheel drive, 3.92 ratio diff and the 5 speed/OD auto transmission. I am not sure if the 20's can stay on the car with the way gas prices are climbing.

 

That's not uncommon. Change your gears and recalibrate your speedo for your computer and you should get some of that back.

 

Should of stuck with some nice new 18 inch to replace the ones that were on there.Plus you will have some tires to ride on with 18"S..........

 

i just pulled my 20's off of my 05 dak, 4.7 lost about 7 miles to the gallon overall. truck did not like the extra rolling resistance. went back to the factory 16's and got alot back.

 

I love my 22's

 

you guys with these big *** rims they look good but perform like crap on off road,I guess there just to look at.there also hell to ride in the city..........................

 

The rims ARE there to look at!! This Durango is the family cruiser not a off road beater.

I have 20's on my 03 Ram and that truck is getting 18+ mpg so it seemed safe to assume that the Durango would not suffer...guess not. Thanks guys.

You have to remember the Durangos are awd so it's putting power to all 4 of those beefy monsters.
