Was going to post in another thread, but deserves its own post imo:
Quick Lesson on tire-grip dynamics:
Your rear tire has G amount it can grip. G is the MAXIMUM force your tire can manage in the form of grip with road surface. When you make a demand of your tire (eg. turning, braking, etc) these take away from G.
So, for example, when you brake, the amount of force it takes to brake will be subtracted from G.
G - B = grip that's left over
If the "grip that's left over" is more than zero, or equal to zero...you will not slide. Your tire will grip. If the amount left over is zero....you are at MAXIMUM braking force. Any more braking force or any demand made of the tire will cause it to LOSE grip and slide. So, that means, mathematically, that if you subtract anything from G, and the number you get is negative....your tire will lose grip and slide.
This is important to know because this formula holds when adding various demands of your tires together. For example:
You are braking AND cornering. Braking force = B.....the force your exerting on your tires due to braking. Cornering force = C.....the force your exerting on your tires due to cornering.
G - B - C = grip thats left over
G is always constant at constant tire temperatures and constant rubber compounds and constant road conditions. So if your tire is at a certain temperature you only have a certain amount of MAXIMUM grip to work with. If you brake AND corner at the same time, both of those are subtracted from your maximum grip. If you were to brake ALONE you can brake HARDER than if you brake AND corner. If you were to corner alone...you can corner HARDER than if you corner AND brake.
That is all common sense to some, but will offer some insight into why.
Also, another thing to learn is:
When road conditions change...your maximum grip changes. For example:
If you ride through gravel, for example, your G-value changes and you can brake less and corner less before you start to lose grip. Since G is smaller, the same formulas of:
G - B = grip thats left over
G - C = grip thats left over
G - B - C = grip thats left over
will allow for SMALLER values of B and C before you lose tire grip and slide.
I know all this is comes as common knowledge to some, but I think delving into it in a bit more detail offers insight and deeper understanding....which is a good thing.
