Hi everyone

My current victa 18 project is nearing completion, I'm looking for an alternative to the ridiculously price original wheels. Does anyone know of some wheels that work as well without the crazy price tag? I'm having trouble finding any victa wheels around my area let alone some that will fit. Would be grateful for any readily available suggestions. Definitely don't need to look original just be functional.
Here's a picture of the mower in question
