We see it all the time on online discussions... "I dont need to worry about load ratings, as I never fully load my Camper".
These are car rated tyres. Rated "88" which is a MAX of 580kg per tyre - 1060kg for the axle.
Fitted to a relatively lightweight T3 Multivan... not a full camper.
The plated maximum axle weights are 1200kg and 1300kg for the front and rear respectively... so a rating of 98 on the rear and 90 on the front as a minimum.
