i think ur question already been asked so many times until we lost count...
for Myvi the recommended will be 195/55 R15 you will get better performance tires and also some comfort performance tire in the range... u can get Yokohama A Drive, Yokohama C Drive,Toyo DRB, Michelin PP2, Michelin Primacy LC, Bridgestone GR80

but if you don want to upgrade stick to 14" then 185/60 R14 which is good in comfort... u can get Yokohama A Drive, Michelin XM1, Toyo Teo Plus

what kinda noise are you talking about please be more specific...

i know the Ori is 175/65 R14 la... lower profile does give you a lil edge but 185/60 R14 we told u here is merely the same height only tire thickness will be different if you upgrade to 15"...
go to the shop tell them i want 195/55 R15 tires Yokohama C Drive... they will tell u... don listen to the recommendation just tell them that... ask them to quote u the price...
write down the names that i give u... that is the comfort tires for ur ride except i wrongly put in the Michelin PP2...

Michelin PP2 is Ultra High Performance tire... slightly lower diameter reading will now affect the handling and comfort too much but the tire side wall stiffness will... compare to Michelin PP2 and Toyo T1R which ppl complaint that PP2 will give you harsher ride but T1R is quite comfort... so it is your choice... whether to change to 185/55 R15 or 195/50 R15 or 195/55 R15 where all of the size PP2 have stock...

from the pic we cannot see lah... even expert also very hard to tell... looks like 16" rim for me..

where do you get that??? the price list with some summary...

applicable for 195/55 R15 only...
For comfort - Michelin Primacy LC, Yokohama C Drive, BS GR80
For Value for money, comfort and a entry performance - Falken Ziex 912
For good Braking in wet/dry, UHP tire with a lil comfort - Hankook V12 Evo, Toyo T1R, Toyo DRB
For anti-hydroplaning, wet handling - GY F1 GSD3, Michelin Pilot Preceda 2 (lower noise compare to other UHP tire)

but the list will never stop... give me ur indicated price/tire... the rims u set a budget for urself also maybe u can get CT or Vios 2nd hand... Klang has a lot...

912 is nice with the Value of $$$... it is cheaper almost similar price with C Drive around RM180 only... but Michelin LC will not give you the 185/55 R15 size i think... so does the 912 also... i think the best bet if you want to use 185/55 R15 is Michelin PP2... actually all the newer cars now they use special size... so tire range is a lil limited... cheers...
the best bang of buck is to 195/55 R15... ur bros will be 195/60 R15...

well it is ur preference... 195/55 R15 has better tires than 185/60 R14, but 185/60 R14 tires is cheaper Michelin XM1 around RM150, Falken 912 RM140... but 195/55 R15 good tires Falken 912 RM180, Michelin PP2 RM240, Yokohama S Drive RM250, Toyo T1R RM250...
of course u pay more u get better tires but if you opt for comfort yes stick to 185/60 R14... 185 width will give you optimal FC while wider tires might increase rolling resistance so FC will increase...

haha... i know a lil only... more on 17" and below... 15" and 14" know already coz using this 2 sizes myself mah...
i threat car tires as no1 priority coz it give away then our life might also... dangerous to have tire that did not give us good amount of traction especially during wet condition...

on the leather seat i suggested u ask in the Myvi thread as there is 1 for it already... sure some of the Myvi owner had already gone thru this process...
