Wheels help please

I use 17 inch winter wheels, and 18 inch summer wheels - both are OEM. There's not a great deal in it comfort wise - my car does have DCC though.

The 18 inch wheels look good and they ride well too - probably the best compromise in size for the Superb - but they are much easier to kerb than the 17 inch wheels. The 19 inch wheels look even better - but they're more expensive.

One final point to note - the 17 inch wheels are much cheaper to get tyres for!
