Good info, thanks for the link. I had been keen to give the K117s a try but won't bother now. Think I'll stick to the GYs wherever possible.

All of these tyres are top performing bits of rubber. Differences are very small in most sections and I would challenge anyone not knowing what was on the car being able to rank them.

Do you know if the drivers were blinded to what they were driving? If not, the results are worthless.

40% of the score was 'subjective', the rest was all based on measurable data.  Of course it's only one tyre size on one car so the value of the data is limited to that context.

Noticeably absent are the bridgestones, stonebridges, goodrides etc.

:laugh:

No mention of blind testing but that's a red herring anyway, the best testers are professional enough to not be swayed by brand names.

I'm passing the link onto a chap I correspond with in the 'States that has an RS and needs tyres after a track day, so nice timing - so thanks for him  8)
These are my thoughts and opinions - sometimes I'm wrong, but not often ;-)

Are you serious??!

Anyone with a scientific background knows that investigator bias is real, can skew results to meaningless levels and is incredibly hard to eliminate.
Properly controlled blinded testing is the only valid test.

Serious !

When it comes to qualitative judgements, blind testing is next to useless.

All it will tell you is if a quantitative difference exists, not whether the difference is better or worse.

Take high end audio for example, its full of real scientists, engineers etc.
None of them use blind testing to sign off on new products.

I couldn't disagree more.
Simply wrong, and allows brand bias to unconsciously influence outcomes. And absolutely true in high end audio too.

I was involved in high end audio for 20+ years and can assure you brand bias is not an issue with the more seasoned participants.

When it comes to artisan endeavours blind testing doesn't get a look in.

Nor does any notion of absolutism.
