I wouldn't say miles better, just have slight edge. MC5 still give good grip and accepted comfort.

Why don't u change to 205/45/16 size? You'll have more choices of tyre.

Wah! So small the tyre width? What car is this?
Actually if don't want to affect car performance, advisable to only go up 10mm, means if you using 16" now, can use 185/50/16. But I think this size even harder to find. If not then go for 185/55/16. Bigger 3% than original size.

Fuel consumption will not be that high.
I was on 185 earlier and then switched to 205.

The fuel consumption has not much difference, still around 13km/l to 14km/l depending on my mood.
But the car stability is much more improved especially during rainy days, on 185, almost everytime when we press the brake harder, ABS will kick in, as the tyre is skidding.
It has never skidded once since I switched to 205 tyre.

my city 185/55/16 looking for tires.. any recommendation except xm2? My exp is xm2 doesnt do well in wet. thats why im not considering it.

currently looking at ps4, but smallest is 205. If i change to 205/50/16, will it be bumpy?

i would like less noise, comfort and grip. thanks.

for honda jazz, anyone using 175/65R15 Michelin XM2? hows the feedback?

i suppose it is better than the stock tyre goodyear gt3?
