Hi,
I just purchased my first Conti Grand Prix 4 season tires and reading the instructions it says that on the sidewall there is a mark for which way to rotate the tire. But I simply can't find this mark . Can anyone explain to me how i looks or help me out in any other way?
thanks

There is a hidden arrow on the sidewall, however it truly.doesn't matter in which direction you mount them.
It's an overrated subject for pretty much all road tires.

Not so much interested in the tread orientation as i agree this is likely irrelevent due to tread designs being symetric and the sipe depth being so low as to reduce the efectiveness to the questionable..
I do wonder though on the ply construction and angle, and its impact on rolling resistance . braking . accelaration etc...
i.e. the tyre may have gretaer stiffness in one plain than another, thus making fronts better on the brkes and the rears better under accelaration etc....
Not saying definitively here, but interested to know if anyone (tyre manufacturer) has data based info on this one...

I rode GP4000s for three years before I knew there was a proper rolling direction - I never bothered to read the directions and never noticed the arrow.
So, I don't think it matters too much. That said, now that I know its there, I look for the arrow and install them properly.

I'm not sure how a bias ply tire (like a bicycle tire) can behave differently depending on rolling direction. Afterall, the the ply threads that angle forward on one side will angle backward on the other, and vice-versa. If they are not made with symmetrical plys, then they will not only be forward/backward assymetrical, they will be right/left assymetrical as well. I'm not sure I'd want to ride a tire like that.

How does this differ from the GP4000 in black, 25mm, which also has the incredible black chilli substance.

Why would they mark it directional? As a marketing ploy suggesting "you see, it's like the expensive car tires, so it must be good!" ?
I guess it's because it's not a slick, it has some "theads"
