Tire Direction

By this definition air and heat are also lubricants. If that is the definition we want to use, then I would agree water is a lubricant. However, the long term effect of using water as a lubricant will increase friction between to metalic surfaces. Therefore I would never say water is an excelent lubricant.

Try sliding down a dry pool slide or a slip'n slide without water and then tell me water is not an excellent lubricant. "Metallic surfaces" has nothing to do with the true definition of a lubricant.

I have never said grooved bike tires will or will not help.

You implied it by saying that hydroplaning is dependent on tread design, and then stating that slicks are worthless in wet conditions:

You are incorrect about hydroplaning. Depending on the tread design a road tire can hydroplane at extreemly low speeds. Racing slicks are worthless with just a sheen of water on the road.

As has been pointed out to you many times, both of these original statements of yours are completely false in regard to bicycle tires.

All of this depends on whether the bike has under steer or over steer in corners,
ie:
is it front engine rear wheel drive, TT-TRI
or mid engine rear wheel drive, Crit-Road,
or mid engine front wheel drive, a Tricycle. 🙄

Edit: I forgot to include,
front engine front wheel drive, a High Wheeler (Penny-Farthing). 🙂

But you're forgetting that force equations have to be balanced. And given that, you need to account for the gravitational force applied by Saturn, as well as the Crab Nebula. Also it's critical to calculate any static charge that might accumulate on the surface of the tire as the result of the tire sliding. If in this calculation it's found that the static charge distribution is not homogeneous, then you'll definitely need to calculate the effects of said distribution on the A-field, as well as caclulate how this charge distribution might alter the zeta potential of the tire surface. Changes in that zeta potential might cause the surface wetting properties of any liquid on the road to change in unpredictable ways. And if that happens--God forbid--then if you're running the tire backwards you might exceed the critical value for air pressure between the tread and the road surface as air accumulates in that space. :eek:

That's eaxctly what I wanted to say! Its amazing, on opposite sides of the globe and we think the same thing! 😄

Mmhmm, I agree. But you didn't contradict yourself repeatedly, close though.

As to oil, in Australia, our cars don't leak a constant film of oil all over our roads, we have laws to prevent that.

You contradicted yourself in regards to force. I know that force if their is no acceleration is equal. While riding a bicycle, the force equation is constantly imbalanced.

If you are pedalling hard and accelerating, you are applying a force greater than that of the aerodynamic and mechanical drag.

If you stop pedalling on the flat, the drag created will be greater than that of the momentum pushing you forwards, thus causing you to decelerate.

If you are accelerating uphill, you are producing a force greater than that of gravity, and all of the drag, thus accelerating.

If you are riding downhill not pedalling, you are accelerating because the force of gravity is greater than the force of aerodynamic and mechanical drag.

All of these situations where here is acceleration give an imbalanced force equation.

Try and hold a perfectly constant speed when you are riding. That never happens, so the force equation is constantly imbalanced.

But if you take into account the gravitational force of the Crab Nebula and the static electricity causing the axle to magnetise the bearings in a Northerly direction, then it would be different.

What a brillient read !! Well done lads.

Does anyone know if the Continental Ultra Gator Skins have to be installed in a certain direction?

Isn't it amazing how threads go off their original subject. 🙄

Friction is a great thing, after all, you can't have sex without it!! 😉
