The problem has been solved!
The K02 tyre is visibly larger, a rough measurement across the diameter easily shows it coming up as 31", while the K0 TYRE is just over 30".
I tried everything, I didn't just remove the bracket on a whim!
My first attempt was cranking the tyre up without any changes to the car or the tyre.
Second I tried letting the air out.
Third I crushed the tyre with a ratchet straps AND removed the bracket.
All I can say is, it is impossible (on my car) to fit a 265/70/16 K02 TYRE In the stock location.
Also everything back there on my car is OEM!
Thanks for the topic, it pushed me to try. I can now run a spare off the roof, albeit a older version of what I'm running.
