Message: <blockquote data-quote="astroboy" data-source="post: 365325" data-attributes="member: 4527">Fact 1: Oxygen molecule is small, so it will seep through the tyre wall and gap. So tyre loss pressure over time and at the same rate for all 4 tyres which RFI will not pick up because the spin rate for all 4 tyres remain.Fact 2: Run Flat tyre has thick side wall to retain its shape when pressure loss, so its impossible to detect visually for pressure loss, even the RFI can't tell if one tyre lost 5 psi. Only pressure gauge can tell.So next question is what pressure is suggested for our rides?? I know there's a tyre pressure guide on the driver's side B-pillar but did u follow?Okay, more confusing or "mafan" stuffs... <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite7" alt=":p" title="Stick Out Tongue    :p" loading="lazy" data-shortname=":p" /> not all petrol kiosk's tyre refill gauge are calibrated the same, always stick to the same pump for consistency or best use a personal air pressure gauge. (I don't have.. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite7" alt=":p" title="Stick Out Tongue    :p" loading="lazy" data-shortname=":p" />)Want to know more? what is the ideal tyre temperature to preform a refill? When tyre is heated up after a drive, the pressure is inflated by a good few psi.. do y'all take this into consideration?</blockquote>
