Tyre pressures

Apparantly I need to have 80psi in my rears (and 61 at the front). Seems a bit high - especially as they're only rated for 69 max!

I had the van weighed, 3340kg, so I split the weight in half for that form - which appears to be a (semi) valid method - after all, it's the 'axle' load they're asking for, rather than the weight on each wheel.

The maximum pressure only applies to the USA ...

Even if you try different configurations of weights and tyre sizes it still gives 80 psi for a single rear axle. Strangely it is very accurate when I input my Tag axle configuration.

Hi

As per other posts, I weighbridged the van fully loaded, emailed the weights, exact make model of van + exact details of tyres, to the tyre manufacturer, Continental, and they emailed me back a chart matrix indicating the safe range of pressures for each axle for optimum safety, tyre wear and comfort.
Pressures were considerably less than Peugeot's generic standard door pillar/Autocruise's handbook readings. Improved comfort on our potholed roads and the tyres have now done 26000 miles with 4-5 mm left and are wearing very evenly with no excess wearing in the centre or outer edges such as you get with overinflation.
