Does a bigger rim cause the gas mileage to decrease? My mpg went down like 5 mpg when i got my rims.

And one more thing, I'm still a newb so please don't give me any meaningless responces. I need help not ridicule.

My rims are konig 17" hurry and they are wrapped in a khumo ecsta asx all season tire. I believe the wheels weigh 22 lbs.



Don't dig on the newb's sig!!!

I've noticed a very slight drop in fuel efficiency after installing my 18's, like maybe 20-30 less miles per tank. But thats it. I think it really depends on how much stop and go driving you do.

yup, mine went down a lot too. but in reality it has to do with how hard you acclerate and how many times you stop like previously stated. but everytime it has to accelerate it has to motivate something heavier.

okay that's cool. thanx for the replies.

...good choice on the wheels. i think they are beautiful...they were just a tad on the heavy side for me. your cornering will be real nice, though.







...don't hate!.. respect people that have talent, even if it is in something you don't like or understand.

yes it will decrease but not by much. if your wheels are heavier than your taking more effort to move the car. its not much to really notice but you will notice the gas mileage will be a little lower

You also have to take into consideration that the rotating mass is greater die to the increased diameter. The farther the mass is from the hub, the more energy it takes to turn the wheel. And since the rims are about as heavy as a stock wheel, it will effect some things. Same goes for braking.
