I put some Michelin PS3's on my car about a month ago replacing Pirellis but until yesterday did not really test them. I was in a bit of a hurry and on a mission due to an emergency and I was comfortably 20 kph better on every corner over the pirellis. For the $185 they cost me they are an awesome tyre. This reminds me of when I first used XAS's about a 100 years ago, a huge leap and fantastic value for money.

keep in mind you are comparing a worn tyre to a new one but yes, the PS3 are a great all-rounder & rarely dissapoint.

These are way better than the Pirellis when they were new and yes, new tyres always a better performance more so in steering input response than anything else.
I suppose unless you get up near the limit of tyre adhesion then they are all the same to the average person. I seldom drive in the metro these days so tend to push it a bit above what the average driver would do. I have always driven faster through corners than most according to some family members.
The Australian Michelin site does not appear to list a PS3 tire with a load rating to fit the Superb. It has a 91 but not a 94. Can you get a 94 load to fit the Superb?
This is the Superb section? No point arguing over something that can't be fitted to the car?
Just because it isn't listed on the Michelin AU website doesn't mean it isn't available as a parallel import locally or as a self import from overseas.
As I previously mentioned, Tempe Tyres carries the 94w. Maybe they haven't got stock at the moment but they can get it if you're willing to wait for the next container.
Just out of interest, would you be able to post a photo of the tyre placard from your vehicle? I'm trying to work out why the Michelin website lists the 91 load rating tyre when searching by "Skoda Superb Elegance".
thx

My tyres are a 91 rating, but let's not get too excited and yell they aren't suitable. The allowed wheel loading is 615 kg per wheel x 4 = 2460 kg. A Superb does not weigh that much and even if the weight distribution was 70/30 to the front the wheel loading would not exceed that figure. The 94 is overkill for the car.

Rather than being fixated on the gross vehicle mass, it's much more important and relevant to focus on the maximum front and rear axle loads of the vehicle. This information should be on a placard affixed somewhere near the bottom of the B-pillar or sill:
This is what's known as a manufacturer’s statutory plate (or "type-approval plate", or "type plate"), which is affixed to every vehicle sold in the European Union, and lists the vehicle's GVM, GCM, maximum front and rear axle loads, and maximum unbraked trailer load, amongst other information.
The trouble is, there's more to wheel and tyre selection than just being able to support the vehicle's static mass.
Even if the maximum axle load does not exceed the maximum load capacity of the tyres, manufacturers don't use this information as the sole indicator in determining what wheel and tyre assembly is suitable for the vehicle. As would be expected, vehicle manufacturers take into account a wide range of variables (including safety margins) when determining such matters, in order to ensure the vehicle remains safe in all conditions that it would reasonably be expected to encounter.
The other concern is that by deviating from the manufacturer's specifications or recommendations, the owner or operator potentially leaves him or herself open to liability, which may have implications on insurance if the vehicle is in breach of the regulations, depending on the nature of the claim.
It's one thing to deviate from the manufacturer's specifications or recommendations, which I have no problem with. You could fit anything from a 205/45 R17 84W tyre to a 255/45 R17 98W tyre on your Skoda Superb if you felt so inclined - it's not my job to enforce the law and it's none of my business.
However, it is quite another to claim the tyres specified by the vehicle manufacturer are "overkill", which is unsubstantiated and is only your opinion.
The only thing you can claim is that Skoda doesn't expressly forbid the fitment of 225/45 R17 91W tyres on a Superb.
(Aside from the fact that any vehicle driven on public roads, which are fitted with tyres of a lesser load index than the OE tyre or whatever the vehicle manufacturer stipulates, would be considered unroadworthy by most jurisdictions and is not recommended on principle by vehicle and tyre manufacturers).
You, nor I, nor anyone else on this forum I suspect, cannot claim with any certainty whether or not the fitment of 225/45 R17 91W tyres will allow a Superb to perform as intended by Skoda.
How you deal with that uncertainty, I leave up to you.
Tell me why there are manufacturers who differ from Skoda's recommendation.
I don't understand your question. You're asking why other other manufacturers specify different load ratings for their cars? They are different cars. Skoda is certifying their cars when they say they comply with all the relevant ADRs.
I believe you can fit different widths up to a point. Even lower speed ratings.
I don't think you can fit a lower load rating. You can fit a higher rating.
