I'm newbie in tyre world , now I'm using 15inch rim and 195/50/15 tyre ~

Any blm owner put 16inch rim ?

Better just leave it as 15'. Your current tire is already pretty thin (9.75cm), if use 16' the tires will be even thinner like wafer and hence the ride quality will be harsh.

im using saga flx changed to r3 rims 16"

cosmetic wise : i like it a lot but comfort wise : kinda fell bumpy

using 205/45/16 tyre by the way

im using 15 last time with yokohama parada 195/50/15 after that upgrade to 16" and using 205/45/16, if 2 person at the back, my tyre will hit fender,
so im back to 15" , no more headache when got passenger

BLM auto or manual?

1st time to heard about put in 16inch... Sure can just over kill ur & engine as weekend car only.

I wonder, can.I use 195/55R15 so there is better ride comfort?

Using FLX Btw.
