Guest Posted June 12, 2008 Share Posted June 12, 2008 This information from "old hand" appears elsewhere on the forum, but it's pinned it here for easy reference. Where a manufacturer's recommended tyre pressure is not available, this formula will allow you to calculate the approximate tyre pressure for your caravan. MTPLM Kg x (Max tyre pressure in psi / (Max tyre load Kg x Number of wheels)) = Running tyre pressure in psi Example: Single axle so 2 tyres Max tyre press = 65psi (written on the tyre wall) Max tyre load = 600Kg (written on the tyre wall) MTPLM = 950 Kg (see plate on caravan chassis) 950kg x (65psi / (600kg x 2)) = 51. 46psi There is further more useful information on tyres from the link below. http://www. tyresafe. org/tyre-safety/caravan-tyre-safety Gordon.
