yeah i'm looking to buy an xb and i want to put 18 inch chrome rims on an xb.
Does anybody know if 18's will decrease the said gas mileage of 30,34 on a stock engine.

What kind of 18's do you have big chrome or racing rims?

 

[iheartmyxb]

I actually found that there was about 5 mpg difference between Jeff's '06 (with 18's) and my '06.5 (with TRD 15's). Mine did better. You may have a different experience though.

My mileage decreased by 10%, it went from 30 to 27 mpg.

with your 18's what tires did you have? 225/40? if so do you have a problem with them rubbing?

 

[HULK]

the only way 18's will decrease your gas mileage is if they are like super heavy and ride like sheeeeeeet

It's all how you drive and the weight of the wheels and tires. Find the weight of the stocks and the aftermarket ones and go from there, i knew calculus was in school for a reason.
