Granturismo tyre size

[V8Smith]

Has anyone changed the rear tyre size on a Granturismo, they have 285/35/20s on the rear but have been looking at options and am thinking to try 285/30 or 305/25 on the back to add grip, has anyone else tried this or any reason I shouldn't?

No one...?

Try asking question on Sports Maserati, may get an answer?

I would be interested in any response, my rears need changing soon.......

Running standard sizes myself and am happy with them. Try on maseratilife.com as US punters often do that sort of thing.

Really enjoying my Granturismo (GTS Auto). Wonder how many there are on PH?
