Hi Kevi
Those 14 inch wheels do look bad and 15 inch alloys would look much better. However there's more to it than fuel efficiency. While upsizing the total difference between the current tyre wheel combo and the one you intend to put shoulnt be more than 3% and it will effect your tachometer and speedometer. With a upsized tyre technically the speedometer should be calibrated again as well to match the increased diameter of the wheel however this is not very common. Following is a tyre calculator link: Tyre Upsizing, Tyre Upsizing Calculator, Tyre Upgrade, Upgrading tyres, Michelin Tyre dealer in chennai, Authorised Michelin Tyre dealer in chennai, Michelin India, Michelin Tyres, tyrestore chennai
Use this to check which tyre alloy combo will be with the 3% difference range. With 15 inch wheel I think you may have to decrease the tyre's sidewall to keep it within 3% or close to it. Good luck.
