14 inch tubeless tyres with alloys will definitely improve the handling of the car and FE will remain the same. the pros and cons of tubeless tyres has been discussed on this forum , someone please help out with the link.
Warranty ? talk to the dealer , i think if u change it at the dealers end it shouldnt affect the warranty , still ask to be sure.
cheers
