LoL....eh compare apple to apple pls....u compare 16" with 18" ??? how to compare...but if 18" is about 1-2kg heavier than 16" ....i consider it light..........

BUT if ur car is 1.8 and go for 18" 225/45/18 donuts........be prepared to feel the car like lorry drive..........cuz as it is now it's actually kinda under powered already.........

so.....solution..go for LCP if u wanna 18" .............

me, i will still go for 17" cuz it's more on application and the need of individual..........

i've dented all my 15" lins on 195/50/15...........so give me a 18" chances are i need to change LINS every year not just donuts........

so hopefully with 17" on 215/50/17 ,  it should be about the same as my 15, so still acceptable.....
