mazda 3 skyactiv & mazda 6 skyactiv also come with i-stop
m2 skyactiv spec showing 185/60 R16 (60 series), can we change to 185/55 R16 (55 series) which same with honda city?
60 series should be more comfort compare to 55 series 

185/60 R16 change to 185/55 R16 you get 3% speedo error.

185/60 r16 change to 205/55 R16 you get 0.9% speedo error.

But 205 mm width I believe would make the car more easy to aquaplane, which is a BAD thing.

is there a 195/55/R16 size? lol

Aquaplaning or hydroplaning by the tires of a road vehicle, aircraft or other wheeled vehicle occurs when a layer of water builds between the wheels of the vehicle and the road surface, leading to a loss of traction that prevents the vehicle from responding to control inputs. If it occurs to all wheels simultaneously, the vehicle becomes, in effect, an uncontrolled sled.

Aquaplaning is a different phenomenon from water on the roadway merely acting as a lubricant. Traction is diminished on wet pavement even when aquaplaning is not occurring

Does this counts? 

If we change rim then everything will be settle.
haha.

205 can fit into 185 width rim?

ya should be closest to our ori size i think 
how does that solve aquaplaning? 
should be ok, just the tyre will bulge out a bit then normal

Not sure leh. Change rim and suitable tyre size will it solve the problem? Based on our tyre for our rim is very rare.

Back to the tint question, base on your experience, which tint can effectively shield heat from the hot sun? Reading shows Huper Optik Ceramic 50 is not a good candidate for heat shield.

My current car is with Eco tint security tint (forgot which series) but it is damn good under hot sun. Can't feel the heat by putting my arm next to the window under hot sun.

However Mazda associated tint shop does not offer Eco tint.

i think the tyre is the one that will make the biggest difference.

What sanadi meant about the aquaplaning is based on the fact that the wider the tyre, the easier for it to aquaplane. but also depends on the tyre pattern and brand in the end
ya i heard ECO not bad but i think nowadays tinting got for 2 purposes

1 is of cause to block out the sun ray, ultra violet light, etc... which is the primary reason to fix tint in the first place

the 2nd is security, which to me i think is more important that blocking out 99% of UV rays but of cause the darker the tint the better la 

the problem is usually the security type tint, wont block out as much as a normal heat shield type tint

If you want Michelin for 195/55 R16, the only one available is Primacy HP. That one costs RM1001 a piece! GULP!

Other than Goodyear Excellence, any other suitable tyres?

Hey guys. Is ray tect cs75 good enough for out car? The spec is not as good as the price.

Hi Sir,

For front windscreen you can choose our 3M Ceramic 75 series which have no problem with smart tag. And the side using Nano series.

Spec for Ceramic 75
(72% VL Transmittance , 40% TSER, 44% IR Rejection, 99% UV Rejection, 19% Glare Reduction)

Spec for Nano 70
(66% VL Transmittance , 50% TSER, 97% IR Rejection, 99.9% UV Rejection, 22% Glare Reduction)


The one with smart tag issue will be crystalline series which have very high IR Rejection which cause Smart Tag that using Infrared to work. As you can see at below the IR rejection at 97%, so you have to compromise the heat rejection with slighly lower spec film so that smart tag can be work.

Spec for Crystalline 70
(68% VL Transmittance , 50% TSER, 97% IR Rejection, 99.9% UV Rejection, 22% Glare Reduction)
