The difference between 17’s & 18’s will be more than ‘marginal’. I had 18’s on my S80, changed to 17’s & it transformed the car in my opinion. Tyres can also make a massive difference, so inspect your existing ones for any bulges etc.

When you say you’ve had a visual check, have you actually checked suspension components for play or just had a quick glance?

I wouldn’t expect much to be wrong with it really, as the mileage is low for an 11 year old car & its not as if those miles were done on roads full of potholes (I assume, as you said the Volvo is used for longer journeys). That’s not to say parts aren’t ‘tired’ though.

Are there any knocking noises at present? I wouldn’t be replacing shock absorbers for the sake of it, as if they’re worn, you’ll know because the car will be riding much harsher. Check the shocks for any leaks (they need replacing if leaking).
