Tyre pressure

[Lew_Alcindor]

Nabasa ko lang sa internet na during hot summer, halos nag-aadd ng +2 psi sa gulong mo ang hot temperature lalo na kapag nasa expressway ka. Kapag nagpapahinga na ang sasakyan mo e mawawala na yung +2 psi sa gulong. Do you think this is true?

Mukang may umabsent sa HS chem class? That is basic gas law. Guy Lussac Law. Pressure increases as temperature increase assuming same volume (tires can expand but only up to a certain point).

If you have TPMS, you would havfe observed that already. With ordinary air, I observe as much as 5psi increase from my garage to SLEX running at speed limit. With nitrogen, the increase is only around 2psi.
