There is too much difference between the air pressure for the circuit and the finger pressure for public roads, and I want to know what is really going on!
ANSWER: There is no problem without changing the specified pressure, try it if you can see the difference!
Why lower it so much for circuit use?
Most supersports air pressure should be around 2.2 in the front and 2.5 to 2.9 in the rear. When it comes to the recommended air pressure for circuit driving, it is 2.1 in the front and 1.6 in the rear, which is so low that you may have misheard it.
If that were the case, it would seem that it would be better or safer to lower it for better grip or safer enjoyment on a winding road. It is natural to be confused when one learns information such as the following. Some may wonder what is really going on and feel that their suspension settings have been turned upside down after they had already arrived at a setting that made riding easier.
So let’s clear up why we recommend such a low air pressure for track riding.
First of all, on a circuit, there are no bumps in the road surface or pavement-damaged holes as there are on public roads. The pressure specified for public roads is around 2.5 to 2.9 after the tire is inflated to avoid the risk of the tire crushing and bending the wheel rim in the event of a major impact.
If the rim of the wheel bends, the tire will instantly lose air pressure because it is tubeless, and the tire will come off the wheel, resulting in a very dangerous situation that can lead to a serious fall. The front tire has a small volume, or to put it simply, it is thin, so the rate of increase in air pressure relative to external pressure is high, and even a large hole with a pressure of 2.0 will not cause the tire to collapse. Remember that grip and handling are not easily affected by changes in air pressure.
The main purpose of lowering the air pressure on a smooth circuit surface is to facilitate control when the surface becomes slippery.
