Wanting tyre recommendations

[Legion]

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.

The Tare is 1655 kg. The gross vehicle mass of a 2013 Skoda Superb sedan is 3935 kg. You also need to consider the dynamic loads on the vehicle. There is a lot of weight transfer when you brake.

PS3 225/45R17 is available as 94W.

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.

That is true.

I have seen on eBay Michelin Pilot Sport 3 tyres available in 225/45 R17 94W XL several times in the past, though not recently.

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".

Tell me why there are manufacturers who differ from Skoda's recommendation.

I think you're referring to Michelin's Australian website (in reference to brad's findings), which in my observation, appears to make suggestions based on the tyre's size designation alone (225/45 R17) and doesn't take the tyre's service description (94W) into account. I think someone needs to go back to the drawing board here.

In contrast, Michelin's European websites (e.g. Michelin United Kingdom or Michelin France) correctly makes recommendations based on size designation and service description.

Despite that, tyre manufacturers almost always defer to the vehicle manufacturer in regards to recommended factory tyre fitments and inflation pressures. Vehicle owners and operators should do likewise. Do not rely solely on a third-party.

The vehicle manufacturer should always be your first point of contact.

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.

Yes, that is how I understand the regulations in NSW.

The Tare is 1655 kg. The gross vehicle mass of a 2013 Skoda Superb sedan is 3935 kg. You also need to consider the dynamic loads on the vehicle. There is a lot of weight transfer when you brake.

The gross combination mass (GCM) should be 3935 kg.

The GCM is simply the maximum braked trailer load of 1800 kg added to the gross vehicle mass (GVM) of 2135 kg.

Again, it is more relevant to focus on the maximum front and rear axle loads, rather than the GVM - but even so, that alone doesn't tell you very much. The only conclusion one can deduce from that is a 225/45 R17 94W XL tyre was deemed appropriate by Skoda to support these loads.

It doesn't necessarily follow that a tyre with a lesser load index would likewise be appropriate, even if it could support the same static axle loads. Apart from the engineers at Skoda, no-one could tell you for certain.

Remember, this just one of many factors which influence the vehicle manufacturer's tyre choice.

If you mean the Michelin AU website recommendation, I think they have stuffed up.

91 is 615kg isn't it? I'd run with it but wouldn't sell them to anyone as the placard says minimum 630kg (disregard the sizes). 15kg per corner difference wouldn't concern me & the chances of it becoming an insurance issue are insignificant. I can understand why others would be averse to this risk.

4" screwnail through the sidewall on RO of my 18k km Dunlop SP Sport Fast Response at the weekend. Too much on to trail across town to Tempe Tyres so settled for two 235/45 17 97W's Pilot Sport 3's from local B Jane on the rear. (If Nov/Dec weren't the months for multiple car regos/insurance etc I'd have had all four).
I'm certain the car is quieter and smoother running with only 50% of the rubber changed.

Bridgestone Turanza.. Serenity Plus... Around $150 each... 225/45/17.. Load 91.... but great grip! Currently Bridgestone has a set of four for $355 as you get one for free... damm good price if you ask me....,

Have these on an AU Falcon and quietness and grip is impressive.

Finally said goodbye to the two remaining Dunlop last week. Pleasantly surprised to get another two 235/45 17 97W Pilot Sport 3 for $139 each fitted and balanced from local BJT outlet. Saved me a drive across Sydney chasing cheap tyres.
