Tyres comfort question

[Ventsi]

It's probably fair to say that there is plenty of evidence to be found in online forums (admittedly a lot of it anecdotal rather than scientific) that Bridgestones by and large have rather stiff sidewalls, leading to road noise and ride comfort complaints.
I'm also a fan of the F1 Assymetric 5 ; although I only have experience of these on a Mercedes.

I have the same experience and also the representative from the company I've been buying tires from for the past 20 years told me the same (bar the road noise, which varies quite a bit)
There is this test that I found yesterday that kind of concerns me. Look at the "subjective comfort" graph:

& that's confirmed by the ranking published in the review at the end.

I'm the management scientist that works on the basis of scores why I use the published tables generated by experts on slid pan circuits rather than board chatter . The guy from Tyre Reviews gets access to the test facilities whilst Autobild do their own testing.

Those All Weather tyre reviews I used on the selection of the Michelin ones. I had a bit of random posting on one thread before the market opened up on the un-usual fit of VAG SUV tyres.

I suppose people who dont believe in the scientific method in decision making may accept straw polls. Expect we will be debating decision theory soon, objective functions and utility objective functions. That is true that those rankings will have a weighted scoring system in them between the factors which you may wish to trade in your own decision . That's if the user had the ability balance those themselves.. ...

Can you please provide some scientific data on which tires are more comfortable?

Your best bet for anybody in the market and wants testing information is the German Autobild site

There are EU standards on testing which it explains. They are sifted and sorted on that and tested by the mag. Opens fine in Edge on English translate. They are the goto site.

The English speaking site does their own testing and reviews but uses theirs as well for reference:

You're best asking questions there since the guy is very helpful and runs a business on his tyre reviews. Anybody who spends their life testing tyres will be an expert.....

As the German article points out it's a fast moving market and prices change as they become popular. With annual improvements I would say user board recommendations get dated which is why I go to these links and not what people say on boards based on old information. You got the cost obviously so you might not want to pay for the best, another variable.

None of these websites provides any scientific data on tire comfort. What they have, on some reviews, is the graph "subjective comfort".

So I ask again, do you have any scientific data on which tires are more comfortable? Because it seems to me that the best we have right now is "straw polls", but I'd love to be proven wrong.

Is comfort not subjective ?.

It's those EU parameters you see in the reviews. You will have to dig.

Starting point:

Tyre Labelling Services | Regulation (EC) No 1222/2009 | CIRS

The REGULATION (EC) No 1222/2009 set out the labelling requirements of tyres with respect to fuel efficiency, wet grip and external rolling noises. Tyre suppliers and distributors are encouraged to label their products before 2012.

www.cirs-reach.com

• the fuel efficiency class (letter A to G, A - the best, G - the worst);
• the wet grip class (letter A to G); at this stage the Regulation only provides classification for wet grip performance for C1 tyres, but intends to introduce a classification for C2 tyres and eventually C3 tyres once tests are available;
• the external rolling noise measured value (in decibels);

Vehicle Certification Agency

Rolling resistance accounts for up to 30% of fuel consumption. EU tyre labelling regulations require manufacturers to display information labels on all tyres.

As been pointed out to you on the thread if you can adjust the DCC you have control over comfort . Personally I don't have DCC. Seats / Cupras have a firm ride, it comes with the territory like Fiats. If you want a soft ride a Citroën might be the car for you.

You are best to take up the conversation on a tyre board...
