Lorry tyre pressures

[qwertyuiop]

1 of my friends thinks that the tyres of my lorry might be a bit soft. I have no idea what pressure they should be and cannot find a plate on the cab door. Anyone any ideas? Its a Volvo FL4.

when you go to the garage to put air in yr tyres, it will display a chart (guildlines) that tell's you

about 90 psi should be near enough on a 7.5 ton upwards ... some normal garage air lines may not go that high, I would take it to a tyre place that does commercial stuff ,and get them to check all your tyres its cheap for piece of mind your and the horses safety...

Look on the tyre. It should give a max load rating at a set psi such as 3500kg at 95psi.

Running lorry tyres under inflated will cause them to heat up excessively and potentailly burst.
