| Mar 16, 2020 at 22:49 | comment | added | Bob D | @ÁrpádSzendrei Rolling friction, which is the major reason for the increase in temperature and pressure in the tire, is due to heat generated during the "squeezing" and "unsqueezing" of the tire synthetic material. Compared to other types of friction heating (such as kinetic friction when skidding) it is generally much less. So when you drive faster, there will be an increase in heating, but the amount of the increase may not be large enough to significantly change the pressure. Hope this helps. | |
| Mar 16, 2020 at 22:31 | comment | added | Árpád Szendrei | thank you, I try to ask why the pressure does not rise when driving faster, so why does the pressure rise only a little, however fast I am driving? | |
| Mar 16, 2020 at 22:30 | comment | added | Bob D | @ÁrpádSzendrei See my update. It's due to rolling friction that results from "squeezing' the rubber of the tire as it rolls. | |
