You can put way more on there than recommended payload and still be ok by all accounts. I’ve got a rim and tyre at 40kg. 4x maxtrax , 1 hilift jack, 1 X 30l drum for my semi automatic washing machine and 5 x 20 L Jerry cans for petrol which I havnt filled yet as picking up proper Jerry can holder’s tomorrow which adds more weight again. The nod is I’ll be OKBut it uses up 33% of your payload.
It looks very strong though.
