What is the ideal tire size for a Ford Focus ST?

I recently bought a Ford Focus ST and I want to upgrade my tires. What would be the best tire size for this car? I want something that can provide good performance and handling on both dry and wet roads.

I would recommend going for tires with a width of 225mm. They provide a good balance between performance and comfort.
