I'm sure a few of you have done this so hoping to draw on some experience.
Currently I've got 17"s on the car with 225/50 tyres. If I were to go up to 18"s does this mean that I'd just need to drop down to 225/45's to keep the same ratio?
And to those who are wearing 45's, how's the ride in comparison, probably a bit harder/bumpier at a guess but is it a lot? Is it bearable?
Do they make the car noisier on the motorway?
Last one, is it worth it?
