Are there any bike tires that can hold 500 lbs (225 kg) each? I'm trying to design a 5 foot by 10 foot trailer to tow behind my bike and wanted to use bike tires.

I googled this: "bike tire load chart" — but found nothing useful there.

The most useful thing I found was a site for "big people" and they had bikes that supported up to 550lbs on 2 wheels.

I am looking for more like 1000lbs on 2 wheels.

Actually I found some charts here and it looks like that about 500 lbs is max.

It looks like a motorcycle tire might be a better bet.  See here
At those weights you're looking at three wheels minimum and maybe four.  

Simply loading 1000 pounds (500 kg) onto a trailer will be difficult without a lifter of some sort, and you would have to balance it perfectly over the axle.  On a car trailer, nose weight can be several hundred kilos acceptably, but on your bike any more than 2-5 kilos could see the whole thing rotate on the axle while loading.

Three wheels with a super-low slung platform would be safer.

You'll also require power brakes because 500 kilos is a LOT of weight.  I've ridden with 100 kilos on a trailer and it was really too much - had problems getting moving, and it was hard to get over intersections from stopped.

A 2 degree upslope in the road to go over a railway crossing damn-near stopped me cold, and the similar downslope on the other side was a surprise too.

Also check with your local road rules about what constitutes a maximum size and weight for a bicycle.  Could be the dimensions you're planning make the bike too big and could be classed as something else.

Don't be a danger to yourself and other road users - this project sounds dangerous.  I'm all for bikes in life, but look to hire movers or use a car trailer for this one.



bikecalculator.com says that a 500 kilo bike with a 75 kilo rider doing 150 watts on the flat will achieve around 15 km/h (9 mph)  Same combo with a bike of 10 kilos is 28 km/h

I haven't got a good calculation for stopping time for those masses from those velocities, but 5 times the weight will take a minimum of 5 times as long and your stopping distance will be much greater, to the point it would be unsafe for you and others to be sharing the roadway.
