Pressures seem to make a big difference with the berlingo. Had mine a week now and TBH I wasn't impressed with the handling, seemed very vague, to the point I was thinking the tracking was out or I had a ball joint away!
Checked the pressures when I filled her up today, 30 all round, upped them to the recommended pressures and was amazed at the difference in ride, Very stable now. Berlingo pressures seem quite high compared to other cars Ive had, probably down to the van base?
It seems to be written into the mechanic's training guide that all tyres should be pumped up to 30psi. Mine came from the main dealer, brand new, with 30psi all round, and it handled like a bowl of jelly.
I've since nudged mine higher and higher, and it's currently at the maximum full-load pressure from the door plate. I don't know what it is in PSI, as I've since bought a pressure gauge that displays Bar so I don't have to muck about converting the numbers every time.
I occasionally carry a full load, as my multispace does get used as a delivery van too. It's a bit too hard for one or two passengers, but it doesn't seem bouncy or hazardous in any way. It's too early to check if the tyres wear evenly like this - theoretically it should wear the centre more, but I doubt it will make that much difference.
