I have 406-47 Schwalbe Marathon Plus tires , Option was stock on my Bike Friday Pocket Llama,
you can order them on line from the Bike Friday Store if you cannot go to any Bike shops ..
Bike Friday used Sun CR 18 in my bike build, I see them in distributor catalogs at the Shop.. (Rims & tires)
check Your Local.
