Default trailer hub question

I was speaking to a trailer parts supplier who said all trailer hubs carry the weight on the wheel studs instead of the centre spigot. Is there a reason for this as it seems strange to me and I thought it was illegal aswell? Does anyone have hubs that carry the weight on the spigot?

Our 3.5t boat trailer carries it on the nuts the center hubs have a 1cm gap all the way around.

Hi. the studs always have carried the load, If the wheel located tight enough on the hub to centralize it you would need a press to get it on and a puller to get it off. Thats why the nuts have tapered seats, to line the wheels up with the studs. Cheers MD

I was going to get in to all the problems of having interference fit wheels but you explained it much better.....

Ok then why did my dads LTD get knocked back during a roadworthy for having one of the hub rings missing? If the studs were meant to carry all the loads then wouldnt hub rings be obselete?

This is actually incorrect. The load is supposed to be carried by the hub and the studs locate the wheels.
In saying that, the studs take a heap of a torque form acceleration and braking.

Actually you're incorrect.

This is a common myth, the hub only serves to centralise the rim, the clamping force of the studs (friction between hub face and rim) bear the load.

On a road car it's a combination of both the studs and hub
Studs stop centrifugal forces being too high with the wheel nuts clamping it
The hub stops the studs from moving too much in any direction under force
Hence why you need hub rings with aftermarket wheels if the centre hole is bigger on the wheel
Plenty of broken studs on cars where people don't run the right hub rings on aftermarket wheels

Yeah a lot of the problem is the alloy reacting with the cast hubs, plus the small tolerances, sometimes welding the wheel to the hub haha
