1010tires has 72.62 to 56.15 on their list in both Aluminum and Plastic. Get the aluminum ones if you do. It may also be worth it to call and ask them what grade of aluminum they manufacture their rings out of. If it's a 2000-series aluminum then it will be pretty soft and may deform. If it's 6000-series or 7000-series then you should be fine!
In all honesty you could probably go to a local machine shop and ask them to make you a set out of high performance aluminum. Drawing up a hubcentric ring in CAD and transfering it to a CNC milling machine shouldn't take more than half an hour....it's not like these are complex forms to create in CAD, it's two circles. Could be easily cut out on a WaterJet from some aluminum plate and then refined on a CNC Mill super easily.
