Tyre technicals...

Lobo:
Today had Michelin Road 5s fitted to my Guzzi. They are correctly orientated.

Intrigued, cause logic suggests to my wee brain that on a soaked road, the tread will gather water, and with further rotation trample / channel / squeeze it towards the centre of the thread... lifting / aquaplaning the tyre.

What am I missing here?

Ta.

royhall:
Push the water away from the tyre centre I would have thought, but I do see where your coming from with the tread pattern and rotation.

Nurse Julie:
I think its 'cos you're in Australia Simon. Gravitational pull of the moon, magnetic fields and all that, pulls the water out, not pushes it in 😊😊😊😊

Ooh I like a good tire discussion.

"I think its 'cos you're in Australia Simon. Gravitational pull of the moon, magnetic fields and all that, pulls the water out, not pushes it in 😊😊😊😊"  ;D

It looks at first description as you see it Simon doesn't it.  I do that "if you roll it round, then which way up is it meeting the tarmac" thing too.

But believe it's because the front wheel has absolutely no traction requirements as it's just rolling along and the curved profile prevents any serious water buildup.

Now put the brakes on and the tire goes straight to traction, but that force is backwards,  so the tread orientation is correct as the tire comes under this load,  flattened a little and water having a wider gap to travel toward under maximum demand of grip.

It’s all in the sipes.

You’ll have to look it up as I couldn’t possibly explain it
