Colombia, Bogota source for tyres and chains
 

Good spot in Bogota for tyres - with or without install. They were working on a few big bikes when I stopped by and seemed to have access to a decent range of makes. I ended up with a Tourance rear & a Battlax front because I was in a rush. I also needed a chain and sprocket, and he got me one within the day so probably worth asking for anything else you need, and they may be able to help.
