Tyre size options

Would really appreciate some help/information regarding tyre size options on a standard 2016 Trophy 220 with standard 18” wheels.

The standard 205 40 18’s look mighty stretched on the standard 7.5j rims (not to mention limited choice of tyres and high prices) so was looking at either 215 40 18 or 225 40 18. Can anyone confirm if these will fit without rubbing issues and without having to fit spacers? Thanks all
