Sadly ADAC have been dead asleep again and missed to assess the presumedly best performing tire in this 205/55 R16. The Michelin PS4 seems to be superior or at the very least as good as Conti's PC6 (see https://www.tyrereviews.com... ) and the PS4 is available for several years in question of this size (even both LI91 and 94). I'm aware it's a classic 911 size (front) and that's surely also what they make them in 225/50 R16 too (rear).
I recently did a test in this size and Michelin really wanted the primacy 4 in it, not the PS4. I will test it sometime though
Agreed, quite probably indeed. However ADAC claim to decide the testing theirselfs. They also say they purchase the tires on local stores. If they actually ask the manufacturer what product he likes to see on the review, the ADAC appear to be somewhat dishonest. Add that to the lack of test data. Entirely contrary to TR. I truely appreciate your job.
ADAC do decide what they want, and buy. But I'm sure they also take suggestions and information from the manufacturers to help decide what to include, and in defense of them, the 16" PS4 would be out of place in a test full of premium touring tires (Though I agree it would be VERY interesting!)
The lack of ADAC data is frustrating, but I believe there's a good business case for them (they sell it back to the manufacturers)
Does anybody know for what weight index were 205/55 R16 tested?
91V, 94V?
I’m in position to buy all 4 new summer tires. I need your expert opinion.
On my VW Passat Variant 2.0TDI is written, weight front 1120kg, back a 1110kg.
I can install 205/55 R16 91V or 205/55 R16 94V or 215/55 R16 97W.
Does the body roll less with bigger weight index?
What is the ride comfort?
Is the smaller tire quieter?
Thanks and regards, Bostjan
Is there any info on the Hankook being the standard or the 4PR version? And what's the difference between them? All I could find out is the 4PR is generally more expensive and a tad lighter, but what's the point in making both versions of every single spec? Rim protection and EU label-wise they're the same too.
You're ahead of me on this one, I don't know anything about the 4PR version!
In 205/55 R16 91V the EAN & MPN are 8808563411880 & 1021023 for the standard version, 8808563390086 & 1019317 for 4PR.
Since EAN means European Article Number and MPN means Manufacturer Part Number, that can explain a lot why we've had such different test results with this particular tire. Most certainly, they come from different factories that don't work with the same specifications. Hankook's quality control to blame!
Premium manufacturer?! Maybe not there yet!
I quoted the numbers for identification only to let those who are interested check what I'm talking about (and is relevant to this particular test).
ADAC's findings here are basically the same as Jonathan's from last year, what stands out is Auto Bild's recent braking test which it aced. So either they got something tweaked, or a midlife update came quietly (delaying the Ventus Prime 4 (or maybe 5 if they don't like 4 for being Asian culture's 13 as Conti & Goodyear do)). Difference in test results can come from the circumstances (weather and track conditions, cars, etc) too.
I have a gut feeling about the 4PR being related to sidewall design. Not that it makes too much sense, but that seems to be the easiest and cheapest to do, and as far as I know Hankook has some history with different sidewall designs (although the SBL mark should cover that). However I doubt it's worth the extra manufacturing and logistics resource.
I'm going to ask Hankook. I expected mid-life update has happened!
Yokohama tires also not included in most recent tests... don't really understand why not...
I'm sure they will have been spoken to about all these tests but declined to be included.
But in this case, the tires were bought by ADAC... Can I assume It's a uninteresting brand in the german market ?
Yokohama declined to be in my tests this year too but no reason was given
Sad to hear that a brand like Yokohama don't attend these tests.
Agreed, I've calls with them planned in the near future to hopefully get them included more :)
You could read Yokohama user reviews here. Later on they could still appear in some independent tests though.
I've used Yokohama tires for quite a while, a few years ago... and still use in one of my cars, and very pleased, specially the with Advan V105. Also used the Bluearth AE-50, which proven to last long and good behavior in wet conditions.
My surprise, is related to the absence of the brand, in recent tire tests... because I think they're always a strong contender.
The V105 has been tested quite a bit - https://www.tyrereviews.com...
It never did really well, and for the price point (they're not cheap) I feel you're better off with your money in a Goodyear or similar.
"It’s a shame there was no Michelin in this test" - couldn't agree more.
I never really was a Michelin fan, but now in need to get new tires in
this size, I'm seriously considering Primacy 4, yet still would love to
see a comparison of more touring Primacy 4 with a bit more sporty Pilot
Sport 4. Both in this size. And here we have test where EGP2 is present
and yet no Primacy. Why, oh why did they do this to us? ;)
True, the Michelin Primacy 4 is in this Autobild recent test: https://www.tyrereviews.com...
Update: ADAC 2021 test with Michelin Primacy 4: 2021 ADAC Summer Tire Test - 225/50 R17: https://www.tyrereviews.com...
Indeed. I read it before this one came out. It's just that this was just braking. Previous test with this tire checked more in-depth was in a different size and then the issue is that the 'same' tire in different sizes is not 'the same' and winner in one size can loose a lot in another one. Side walls change, thread pattern changes (or additional row of blocks is added / removed compared to different width) and so on. And hardly ever anyone compares different types from the same manufacturer, to show touring / HP etc. in one test with multiple brands from the same class - same car, same size, same conditions, just different brand's. Hell of a work, but that would really be something :)
It's actually interesting as to why. ADAC buy all the tires on the open market, and it turns out they accidentally bought an OE approved tire (S1 I believe) and as the marking was so small, they didn't notice it until later in the testing.
As the tire was modified for the OE, starting with less tread depth for lower noise, they didn't think it was fair to include it in the overall grades.
Lol! Thanks for sharing that. It's really hilarious that they realized late enough not to buy another, regular set and do the test with them.
