I bought my 2011 C3 Picasso at 3 years old, and drove it home to Devon from Yorkshire. I was immediately impressed by how flat and stable it drove - it felt like a skateboard - after my slightly lumbering Zafira, but I then went through a rough-surfaced roadwork chicane at low speed and felt the rear skitter sideways; that was a surprise. Come that winter and first flurry of snow on the country roads, I could barely keep the rear attached to the car going round bends - it broke away at the first opportunity.
It also 'crashed' about on potholes and ridges and this was getting on my wick a bit.
The 17" (and 7" wide) 'Clover' wheels were also already well 'kerbed' when I bought the car at 21k miles, and I added to that almost from day one - if you as much as touched a kerb when parking, they were scored. The increasingly poor state of our roads with potholes aplenty made me realise that I hated low profiles tyres, especially when they sat on rims which were the virtual same width.
I settled on a set of 16" alloys from a C5 no less (the older models had only 4-studs) and colour-coded them to suit the BlackCherry. They now have 55-profile 205s on them, and the improvement is very clear. It has renewed my enjoyment of the car; it really is a tough car to beat for room, comfort and overall ability.
My old - and scuffed - Clovers sold easily on eBay; the buyer had them professionally refurbished in black and machined alloy. I wonder if they still look good...
I now have a unique BlackCherry - which rides significantly better than before.
When it comes to tyres, I can thoroughly recommend 'Goodyear EfficientGrip Performance' tyres at only around £64 a corner fitted. They are BAA rated - B for fuel economy (that's good), A for wet-weather grip (that's superb) and also only 68db noise level - that's very low and instantly noticeable improvement there too.
I bet you'll find plenty of 16" alloys on eBay to try, and most will come with usable tyres (tho' swap them for the Goodyears at the first opportunity!). Also have a search for 'breaking C3 Picasso' and enquire about the alloys - condition, etc. Finally try https://www.1stchoice.co.uk/ - I can also thoroughly recommend them. Simple as it gets - enter your reg number (or car details) and click on set of alloys 16".
Please keep us posted if you decided to go through with this - it would be interesting info for others too :-) .
