225/45 17inch vs 225/45 18inch

[rusty]

Assuming we have the same brand & type of tyres fitted on the same car, which one is harsher/more comfortable in term of ride comfort?
Is the 18inch harsher?
What about handling? I reckon the 18inc handles better.

I reckon the 18inc handles better.

this is based on..... ?

2254517 and 2254518 are two totally different sizes. you wouldnt replace one with the other unless you mean you have a set of each and want to know which one is better for handling and comfort?

ie a 2254517 would be replaced with a 215/225/235 40 18 etc...
