Hi, I'm thinking to upgrade my tyre..
currently using GY NCT5 195/60R15.

is it adviseable to upgrade to 205/50R16?
the grip is improve abit(actually i'm satisfy with my NCT5 grip). but the tyre price is very very huge difference.
Michelin Premacy LC
15 = RM 280
16 = RM 410

Another thing.... if compare Premacy LC vs XM1, which one is better? i prefer more quiet tyre but the shop guys told me XM1 have better grip than PLC? As he said during raining, the PLC grip is very bad and worst than NCT5

Wanna check with you guys,
normally u go change tyre when is the manufacture date? 1month? 3month, 6month 9month or 1year?
I just change from my 17k mileadge NCT5 to Michelin Primacy LC, but the noise level is almost the same and i cant feel so much improvement, is it bcoz of my new michelin LC tyre is 9month old? Yr 2609.
Compare to when i got my new car with new NCT5, its more quiet than current tyre.
Can i request them to change to new tyre for me?
