No, front 19s are going to be difficult in Cuzco. I don't live there and things are always in flux, but they are your best option. Lima definitely would but I recommend you ONLY enter and exit Lima from the south. North and East out of Lima is extremely dangerous traffic and even illegal for motorcycles.

Riding a F800GS, I left my home in New Jersey with Anakees mounted, plus a Heidenau rear and Mofo front strapped across the back seat. I had the luxury of swapping them out as the road surface went from tarmac to dirt and back to tarmac.

The Anakee wore out deep into Brazil and the Heidenau give up the ghost in Peru. Bought a Brazilian made Pirelli in Cusco, a street tire as the dirt portion of my extended trip was pretty much done. The Pirelli lasted until Mexico City... Yes, you can find tires, but you might not find the tire that you want. Would I do it again? No, because the next few trips will be in 250cc chinese bike and tires will be both cheap and easy to find in South America.

PS: I crafted a thin round sheet of plywood as a lid/cover for the stack of tires stropped across the back seat, then stored a few things in the space. Later I bought a small duffle bag to hold the things I probably didn't really need when the tires wore out.

Tell me about it! I got pulled over arriving into Lima from the North. Lima is unfortunately my least favourite large city in all of my travels. I reallt want to avoid it if I can.

Gonna stop in La Paz on my way out of Bolivia and might buy there if there is available tire.

Not sure what you are looking for, but there is a BMW dealer in La Paz which is easy to find. I don't think they sell tires. There is a cluster of motorcycle shops in the Calacoto neighborhood, the southeast part of La Paz. I checked a few out but couldn't find what I wanted, so I rode on to Cusco. The Honda dealer in Cusco took me to a shop near the center of town where I bought the Pirelli and Honda mounted it.

The next day as I climbed the western hills leaving Cusco, something didn't feel right in my back tire. Back to the Honda dealer to have the rear wheel bearing replaced... Another night in Cusco, not so bad.

I bought some Metzelers from Todo Moto in La Paz, asked him to produce a receipt with reduced cost just in case.

When I crossed into Peru, sunat guy pointed at my new tires and said "repuestos" then I pointed and my worn out tires on the bike and said. Boy a instalar en Cusco. And that was it. No fees.
