1% is quite small difference.
Thinking of changing back to stock 15" rims and tires.
Wanna see the difference.
Heavier rim affect torque output hence consume more petrol
Suspect la... we see how.
not entirely true that bigger rims are heavier.
my stock Ford Focus TDCi 16' rims are heavier than a Vossen CV5 17' rims.
it really depends on which type of rims you buy.

Actually I didn't change them.
It came with the car ..bought 2nd hand.
You think 16" is ok?
Looks nice though ... I like it.
But I heard the tyres price is a killer.

16' tyres cost is definitely higher than 15's.
a PS3 205/55/16 cost RM380-420 per pcs, whereas a cheaper alternative like Kumho Ecsta7 cost around RM250-280 per pcs.
On the extreme part, my friend installed Advan AD08R RM880 per pcs on his TDCi.

again, depends on what brand and model of tyre you want.
