Hi guys,
Can anyone explain to me why bigger rims will lead to worse fuel consumption?
I'm thinking of upgrading from 17" to 18".
Thanks!

In layman terms, an increase in rim size also equates to an increase in tyre width. Bigger contact patch, more rolling resistance and hence higher fuel consumption.
By that same token, more friction also means better grip, which is why you will feel an improvement in the handling of your car.
though to some degree you could theoretically get bigger tyres with less rolling resistance... and still not suffer too much in the fuel department but suffer in the handling
TS,If you dont want the FC to suffer take this example as a reference..
If you're using 215/50-17 wanna upgrade to 18 make sure your new 18inch rims weight less than the 17 one.Tyre recommend is 225/40 then the rotation will be quite same.
