gas mileage new rims

i just recently installed x runner rims on my standard cab and wanted to know do people get less mileage with x runner rims compared to stocks???? it seem like im getting 15-20 mpg less. My truck is all stock

 

15-20 less? recalculate bud.....

 

it more????

 

or lesss

 

15-20 MPG less?!?! much much much much x1000 You should maybe be losing 1-3 if your losing but not 15-20 MPG

 

what like 10 mpg

 

theres no way its the rims. i honestly think if you are losing 15mpg theres obviously something else wrong

 

MPG is how many MILES your truck GOES per GALLON. So lets say before you did the wheels you were at maybe 25... if you LOST 15-20 MPG you would be getting 5-10 MPG so I think maybe you mistyped what you meant to say

oh and BTW the x-runners get the same gas mileage the V6 get more or less, depends on the setup but stock it should get the sameish

 

the rims wouldnt hurt your mileage that much.at least i dont think so

 

he has an I4. he just got xr rims

 

I know he has a I4 which is why I stated starting out at 25 mpg

 

ok....

 

are you sure you calulated it right?

 

i think soo soo would it drop a lot cause the rims are bigger and heavier

 

I think the OP meant per tank.

If the rims and tires are wider, you can expect a drop due to rolling resistance.

See it all the time on the Jeep forums.

 

If you are loosing 15-20 MPG they must of forgot to install the tires.

 

rolling resistance???

per half tank how much dropped

 

Yes, this caused a dramatic drop in mileage when I went from the horrible Dunlop steelies that came with my SR5 (inline 2.7L four) to X-runner wheels with brand new rubber. I did it at ~8000 miles, so was fully broken in. I was routinely getting 25-27MPG on highway driving to work. Then after I installed the new wheels/tires, I am getting 19.5 - 20.0 MPG same driving, same places!

There was a test in Car & Driver (I think) where they put a VW through the tests with stock wheels, then +1, +2, and +3 profile wheels/tires and the drop was very similar.

So, you're not crazy - it really happens!

To the above post, he is staying as low as 15 on a 4 banger! I dont get that low with a 4 cylinder prerunner, lift, 46 pound tires and aftermarket wheels...

 

i wqas guessing on the mileage loss
