Sid, with credit to Gambalunga, I changed the tyre profile last year, due to the low ground clearance on my 2011 Plus 4. It does make enough of a difference to be worth it.
The original tyres were 195/60/15 88H and the new tyres are 195/65/15 95H, these give approx additional 10mm clearance.
The tyre does fit into the spare wheel hole with the Cyclopes rear lamp. If you are unsure ask the tyre fitter to try the reacement tyre before you commit.
The accuracy of the speedometer readings inproved on my car when measured against GPS, and cosmetically I prefer the way the tyre fills the wheel arches.
