Thanks Bro Vr2turbo,
I will seriously consider to the Falken Ze912 as most of the forummers also have good impression to this tyre. At the 1st place I dare not consider Falken as many of my friends saying that Falken tyres always have good performance in the early stage after some time it become worst. Anyways, i will keep browsing this forum to gather more info as I felt that the comment post in this forum is very useful & their opinion also moderate.

Bro Vr2turbo,
Just want to ask you any comment to Yokohama C-Drive? How much the price in the market?
Thank you.

Most tyres perform best when new.
Tyres with harder rubber compound normally have sipes (lines cut into the pattern to soften the block). If you take closer attention and look at a half worn tyres of this category the sipes will shorten or become smaller and therefore the rubber block hardens and tyre handling becomes bad especially in the wet. Same time the center grooves will become shallow and smaller.
UHP performance tyres normally have softer rubber compound and their pattern normally are in blocks, therefore when they wear down not much changes except that the grooves gets shallow and smaller.
Please refer to this website for more info on " Sipes "

>>>Just want to ask you any comment to Yokohama C-Drive? How much the price in the market?<<<
The C-Drive should be in the Yoko Mid range but the C-Drives are now made in the Philippines. Therefore I am not sure whether there are any changes in their performance.
Sorry, I do not have the price of this tyres. You can refer to "Tyre Shop" posting for some contact and call them for the price.

rdgs,

Dear all Sifu...
I'm newbie here. I'm planning to changed my City stock tyres soon. I'm thinking upgrade it from 185/55/R15 to 195/55R15.
I did read through quit no of the posting in this forum, many forummers are recommend to Falken 912.
I'm prefer comfartable & quit rides. In my mind, i have few options they are: Yokohama A-Drive, Falken 912, Goodyear Excellence and Hankook Evo V12. My budget is within RM180 per pcs. Need some advice from all expert here. Which is more suitable & value for money. I'm from Alor Star. Thank you very much.

If upgrading from 185/55 R15 to a wider 195mm tyre on the same 15 inch rim, you must drop the Aspect Ratio by 5 points, to 50. This will maintain the rolling radius and, hence, maintain accurate speedometer reading. So, the correct size should be 195/50 R15.

Also, watch the Load Rating. The replacement tyre must have a load-carrying-capacity that is equal to or greater than the factory tire. For example, if factory tyre is 91W, but replacement tyre is 87W, it’s a no-no!

Thanks again from your advice Bro Vr2turbo. rolleyes.gif

Bro Freshoil, 50 series tyre for me is too thin, hence i will become more pumppy. I will stick to 55 series as the different of the tyre diameter is 1.88% only it still within the +-3% changes. Anyways i will look in to the Load Rating as per your reminder. Thanks...

Normally what is the maximum load for 195/55/R15 tyres? The maximum load for my City stock tyres (185/55/R15) is 475kg if i not mistaken!

idsi,

The Aspect Ratio indicates tyre sidewall height in relation to tyre width. For a 185/55 R15 series tyre, the “185” is the tyre width in mm, and “55” means the tyre’s sidewall-height is 55% of its width (101.75mm). A 195/55 R15 series tyre’s sidewall height will be 107.25

That is why, as the width increases, the aspect ratio is reduced. To keep within the 3 percent rule when using the same rim size but wider tyres, for every 10mm increase in width, aspect ratio is lowered 5 points. 185/55 R15 to 195/55 R15 increases overall tyre radius/diameter by more than 3%.

For load-carrying capacity, look at the Load Index number on the sidewall of the tyre, like 87H, 90V...etc. The number is the load index. The higher the number, the greater the load-carrying capacity. The letter (H, V, W and such) is the Speed Rating. The common speed ratings found in tyres, currently, are H (210km/h), V (240km/h), W (270km/h), and Y (300km/h).

From 185/55/R15 to 195/55/R15 the overall diameter is increased by 1.84% only and not more then 3% as mentioned.
For 195/50/R15 it is smaller by 1.48%. Both can be used but since 185/55/R15 already looks small on the CT, the 195/55/R15 is a better option.
For load range you don't have to worry. The bigger the tyre the higher the load range, meaning from 185/55 to 195/55 the load range increases.

Ya, I felt that 195/55/R15 tyres is more match to the City as the stock tyres really looks "slim".
