Some more information about the Temperature/Traction/Treadwear Rating....
Quote:
The temperature rating - an indicator of how well the tyre withstands heat buildup. "A" is the highest rating; "C" is the lowest.
The traction rating - an indicator of how well the tyre is capable of stopping on wet pavement. "AA" is the highest rating; "C" is the lowest.
The tread-wear rating - a comparative rating for the useful life of the tyre's tread. A tyre with a tread-wear rating of 200, for example, could be expected to last twice as long as one with a rating of 100. Tread-wear grades typically range between 60 and 600 in 20-point increments. It is important to consider that this is a relative indicator, and the actual life of a tyre's tread will be affected by quality of road surfaces, type of driving, correct tyre inflation, proper wheel alignment and other variable factors. In other words, don't think that a tread-wear rating of 100 means a 30,000 mile tyre.

My first impression of the MRF Perfinza is extremely positive.
The ride comfort has gone up substantially. Keep in mind, the air pressure is the same. There is a certain plushness in the ride that I normally associate with Michelin tyres! Very surprising!
Over broken roads, the car feels a bit more composed and bounces around a bit lesser. On very sharp potholes, speed breakers, the car's stifer suspension still throws the car around a bit but it feels a bit more damped with the MRFs than I experienced with the Hankooks.
On rough roads (you know, the type where the road is broken, but there is no pothole as such, you can still drive at the same speed you were doing earlier, but the tyre noise is much more and you can feel more vibrations), the MRFs are in a different class compared to the Hankooks. The Hankooks transmitted a lot of the harshness into the passenger cabin (both, by sound and feel), but the MRFs do a great job isolating you from the harshness.
Road noise at 120kmph is much lesser on the MRFs. However, there is still a hum or a whoop whoop noise which is audible around 120. It was much louder on the Hankooks.
At other speeds too, the MRFs are a bit more silent and I'm enjoying that for sure.
Performance:
This is the critical one. Unfortunately, I do not have anything concrete to say about this. I havent pushed the car around a bend to really see what these MRFs can do. I did do about 160-180 kmph on a closed road (people familiar with NICE Road-Clover Leaf junction will know this) and the MRFs braked very well. No fuss, no drama, no ABS kicking in. The car just stopped smoothly but quickly.
I've taken a few highway curves around 80-100 kmph and the MRFs didnt break a sweat.
The true test would be when I go on a proper highway drive. Hopefully it will happen in a couple of weeks.
I shall update the thread when that happens.
Important Note:
I removed the suspension blocks in Calicut and once I returned to Bangalore, I could really feel the difference. The roads I drive on in the city are roads I'm very familiar with. I've driven my Civic, my vRS with the suspension blocks and now the vRS without the suspension blocks. The vRS' stock suspension is beautifully designed and works very well. It is a bit stiff and bad roads arent really something I can glide over but they are a thousand times better than earlier.
Even before I changed the Hankooks to MRFs, I really started enjoying the ride of the car and started looking for reasons to drive, even within the city!
So, I did experience the lovely ride of the car with the Hankooks and that is what I am comparing with the Perfinza.
Drawbacks?
Frankly, cant think of anything at the moment. As I mentioned previously, my only concern is how well they hold up under sustained highway high speed cruising. Higher temperatures generally lead to poorer tyre performance and I'm curious to see how the MRFs perform.
My old Hankooks:
It was a shock to see one Hankook tyre(I'm not sure where it was running) having a cut on the beading. It could be due to an impact (given how much I've driven), but it's unlikely. In any case, it's yet another proof of Skoda's poor decision to give these tyres with the car. A clear case of trying to save a few bucks. What really riles me up is the behaviour of Skoda. Each and every media car talks about the Michelin PS4 and how great the tyre is. But all customer cars have been delivered with Hankooks, thus robbing the paying customer of actually getting the best available tyres. And to save what? 20k per car?
I wonder why Autocar or Overdrive or any of these publications even pander to such nonsense? They should jsut mention in their reviews that the test car came with Michelins but customer cars are being delivered with Hankooks and keep silent about it.
Anyway, apart from that, the other tyres are in good shape. It is very evident that the front and rear are worn differently.
The below pics show one front and one rear tyre. You can see the front tyre is worn more. The edges of the grooves are sharper. The rear tyres on the other hand have more rounded edges.

The MRFs arent cheap as such. At least not in this size. They are somewhere close to 11k or so. Need to recheck. Michelin PS4 ST in the same size costs 12,210/-. So, the MRFs are about 10% cheaper than the Michelins. They have a big task ahead of them at this price.
