Evening everyone.
Given context:
Ford Fiesta, 1150kg, tyre size 195/55R15
By reading the forum, I found people commenting about this tyre good, that tyre not good, this good on wet.
I would like to know, how do you guys judge the tyre performance? in what context and measuring method makes you conclude that this is good and that is bad?
Dry/Wet Grip:
Like do you test it personally in rain? Purposely run into the water in highway? jam break? sweep corner?
Noise:
Do you feel by your ears only or you have device to record the dB?
There are many factors can affect the noise, how do you judge if it is good? solely base on feel?
Comfort:
This is very subjective, absolutely hard to gather data such as vibration generated on this road
Treadwear:
This is easy, can count by mileage
I am currently using Toyo CR1, I can't tell if it is good and can't justify the money spent. I have also use XM2 previously, I feel both are same with RM100 price difference per tyre (absolutely noob that I don't have the capability to differentiate both), I feel XM2 seems to last longer than CR1.
The only reason if ppl ask me why I se CR1, i can only tell it is more budget friendly and it is not unknown brand.
Thus would like to learn how should I judge a tyre.
if your car got abs, then wanna test out performance in wet braking, just find an empty road, jam brake when safe, see how far it takes to stop. Next time when you change another tyre (different brand) try again and see? Given context:

as for wet grip, sometimes you can feel it when driving through corners, on painted lines.. you'll feel the tyres not reacting to your steering input.. especially when you passed by those construction areas with the temporary yellow lines for temporary change in the lanes.. those are slick af.. I kena before, steer right, but car kept straight.. sketchy
as for noise, just use your ears lo.. surely you'll drive the same road everyday in and out when go to work or coming home.. try to observe and see how loud / noisy is it when you're using 2 different set of tyres?
of course the road surface plays a role, rough or newly paved, but then its your everyday road.. surely you'll notice the difference
comfort - tough to judge. suspension also comes into play, unless you really go bump into potholes and go through speedbumps at high speed.. but why wanna wreck your car just to test comfort right? so pass...
