Hi Toby,
Welcome to the forum. As you may know, the EXOs haven't been available in the UK for too long so there are not too many mods and tutorials around yet. The ones you have found on the old models have been created and improved over years. I imagine making tire armour would not be too different for the EXO's; Same process but with different measurements. The bit that would be different is where the frame connects to the spring. I guess you could have an area in the armour that just goes over the bolts at the back with a gap at the front or do the armour in 2 sections. I don't really know!!
There was a lot of emphasis on hoof protection for the old models because the hoof rubber wore very quickly, with these it is massively improved. Unless you need an increase in grip for wet grass or something I would stick to just the hoofs. They last amazingly, it's probably cheaper to use them than tires, the grip is generally good and you don't have the problems with slipping tiresocks or the hassle of making them.
If you do any mods maybe you could make a tutorial for others?
