    Hi
    Can you guys help me with guidance on pressures for my 15" fuchs replica wheels fitted with 195/70 c r15 tyres (102H rated)?

    Typical camper van set up so often fully loaded at rear!

    Currently running 30psi front and 40 rear

    Thanks

    Same diameter as stock, same load, same pressure.
    Go a bit higher than 40psi at the rear maybe.

    If it has been lowered, looks maybe in your profile picture, then the inside edges will wear down to cords while there is well over 5mm tread on the outer edge, as the spring plates twist as suspension rises up.
    Too much camber looks cool but overdoes loading up the inside edge on corners.
    The bit that wears off first is not even touching the ground when the bus is sitting still.

    Thanks.
    I think it has been lowered but the camber does not look excessive and the current tyres are evenly worn [edit: just measured and rears are 5mm both inside and outside edge].
    So is 30 at the front correct? What extra at the rear then 42-45?
    Thanks

    I have the same size wheels and tyres and use 30psi front, 40psi rear. You could go up to 44psi at the rear.

    I see your problem, that’s quite an impact.
    Mine does have a slight camber too but cannot see the contact point as on gravel.
    Next time I am on the road I must have a look...
