For folks in the US, Amazon right now has Escape size
Carlisle Radial Trail HD Trailer Radial Tire - 205/75R15 107M tires on sale for $53 each plus an extra $15 off if it is your first tire order from Amazon. I just ordered 2 for my utility trailer that takes the same size as Escapes. These are the D rated models, the standard Escape install is the C rated version of this same tire. My delivered total was $91 plus tax for 2.
I don't have any idea how long this price will last - Amazon sometimes changes these things very quickly.
