I have purchased a new Swift VXi. I want to go for alloy wheels for my car. Swift VXi comes with standard fitting of R14 wheels. I will be going for 4 new alloys and keep one of the original tyres as a spare. Should I go for a R15 / R16 wheel by reducing the size of the rubber portion alongside (i.e. Big Alloy Wheel & Smaller Rubber Part) or shall i puchase alloys of R14 itself? Which alloys will give better comfort? What will be the estimated price of my current wheels. (My car is 2 weeks old.) Please suggest name of good alloy wheel manufacturers and a place in Mumbai where i can get a variety as well as good quality of alloys.
