Hi,
I fitted 205/65/15 Avon ZV7 tyres to my 2014 Plus 4. No issues with clearance, slight increase in ride-height and they look better in the wheel arches. Also slight improvement in ride comfort (at 22 psi) with the higher sidewalls. No discernible change in handling.205/60/15 were standard on my Morgan alloy wheels -- maybe if u have wire wheels they fit skinier tyres as standard. Hope this helps.
