Boxster wheel load rating

Hi,

Can anyone please tell me what the maximum load rating is for a standard Boxster wheel.

I have an aircooled VW T3 Westfalia and bought a set after seeing that other people fit them to their vans and seeking advice on a van forum. However, embossed on the back of one of the spokes is FR=4800N and I'd like confirmation, or otherwise, that this is the maximum load rating.

This is the type of wheel:-



Thanks in advance,

Chris
