Bro, ur profile too low... thus with using BLM.... i believe ur current tyre doesn't give u much comfort . Just like my own brother, doesn't listen, then regret.
185/55/15 would be a good choice for BLM size, otherwise 195/55r15 would be too heavy for ur car.

185/55/15. 195/55/15 will rub the inner sidewall on full load due to softer stock suspension. higher fc and further braking distance.
ze912 or ps3 is decent.

imho, yngwie was mentioning using 195/55/15 will cause the tyre rubbing especially when carrying full passengers or full with luggage / stuff because of
1. thicker profile than 185/55
2. soft / comfort stock / oem suspension

but the saga flx 1.6 is already running on stock 195/50R15 rubbers right? perhaps could consider this size too, no?

overall diameter for:
stock 186/60R14 = 577.59 mm
185/55R15 = 584.45 mm (+1.19%)
195/50R15 = 575.81 mm (-0.31%)
195/55R15 = 584.45 mm (+3.08%) 

NVH is among the best comparable with continental's  cc5

grip on dry is pretty good, whack the car all day erry day.

wet is decent too though not as good as competitors considering it is a comfort/low NVH based tire. that said, i've driven on heavy rain on MEX highway straight line for over 170 km/h. (kids please do NOT try this yourself)

195/55/15 c drive 2.
~220-230 or so per tire iinm (quite some time already)

uncommon sizes hard to find. perhaps can pm kent aka nestum (LYN ID) in this forum

195/50/15 should be okay on blm with stock suspension setup.
and since the stock suspension is on the soft side, changing to thinner sidewall should not affect the comfort so much. the handling improvement can compensate the different.
btw, by looking at the tread's depth / grooves, tires experts could tell that c.drive2 isn't the quieter tires around.
wet handling may increased over the older c.drive but it can be noisy at high speed.

bad train of thought. if comfort is your priority, please forget about lowering the car unless you're gonna invest in good spring/absorbers or adjustable (easily minimum of 2-3k ringgit even on basic proton rides)

i use r3 with 60 series profile, comfort ok la, not much rattling and noise... less bumpy also

very expensive ones such as eibach/H&R/titan/RCS those kind

thats why if you want comfort, forget about lowering rides

go for neuton nt5000 for budget tire. Good wet n dry grip + very cheap. worth the money
