I'm looking to upgrade the wheels on my 2018 Superb SE technology estate. It's currently on the standard 17" wheels but thinking about fitting either 18" or 19" wheels. Any advice on the pro/cons on both sizes would be much appreciated. Also what is the correct tyre size for both?

They'll make the ride harder and increase road noise relative to the standard 17s.

I've fitted 18's to my S which should have 16's on. Aesthetically they are far better and fill the arches now. Not noticed much increase in hardness or road noise but tyre choice will be a factor. 234/45/18 are the recommended fitment not sure what 19's would be but google will tell you.

For 19 in. wheels, tyres size is 235/40/19. It’s a bit harder than 17 in. wheels but mine is DCC equiped. This may be a bias for comparison.

 

Note: Depending on your engine, it may be wiser to chose 18 in rather 19 to minimize the rotating mass increase. Otherwise you may have the impression that your engine has lost power.
