Lawrence, I think you will be able to work with bicycle tires. There are some very stout ones and you need strength. Consider: http://www.amazon.com/Maxxis-Hookworm-Urban-Bike-Tire/dp/B0021G9ZIE To bad they don't make 24" tires. 24" wheels will be stronger than 26" Pump up the Hookworms to 1i0psi and they will be LRR.
Build the wheels using off road rims like: http://sun-ringle.com/bmx/rims/rhyno-lite-xl/ And consider tandem gear. Your steered wheels may require a hub that can be supported on one side. Hubs that take a larger, stronger axle (1/2") are used on trikes. Greenspeed (in Oz) has proprietary hubs that are extra strong because how the spoke holes are oriented. http://www.greenspeed.com.au/gtt.html They also have very nice proprietary rims but they are smaller diameter and you probably could not get hard durable tires for them. I should warn you that bicycle tires don't have the life of motorized cycle tires. I can't help you there, but it is worth looking into motorcycle tires. It could be very expensive with bicycle tires. You will pay minimum $30 a tire and they may not get you 5000 miles. Small road worthy motorcycles might be a good place to look for sturdy tires. There used to be little skinny tires on 200cc Ducatis, Moto Morinis, Yamahas, and so on. The "cafe racer" market, more of a Euro thing than US. The wheels and hubs for those might be a good idea for investigation also.
