Default where did my MPG's go?????...

Well i put on some new rims. 18 OZ ultraleggeras with some 225 40 18 falken's on about two tank fulls ago, averaged around 340 miles. This one i hope that i get 300 miles on a tank. I know that they weigh about a half pound more than my stock rims and the radius is much smaller, but should it affect my mpg's this much? I used to get 375 to 400 pretty easy with my stockers on. Should i be concerned? Thanks for the advice.

Default My brother has the same rims

He said he did not notice any difference when he put the rims on. You probably are just driving a little different than usual.... showing off the rims.... I know when i do something to my car i usually drive alot harder then normal.... leading to less MPG.

Default Check air pressure, and perhaps get a more accurate way to measure MPG

Default could be due to tires - preformance tires are sticker then all season tires

which could be a reason why a drop in mpg - but that sounds about right cuz i have 18" and SL OZ
