You might want to hold onto something for this one. I am driving fiat panda on 13 inch wheels. Yep try not to faint.
I currently have the cross climates fitted to the front only, my justification for this is when fitted it was starting to get cold and winter was coming, my rear tyres were almost new summer tyres and I would rather have grip on the front end over the winter on my front wheel drive. This was not an issue for the MOT and wasn't even mentioned. The only issue I might have is that in other European countries this will be illegal as you must have the same season tyres fitted front and back, plus Austria and parts of Germany still require you to have winter or mud and snow tyres fitted to all 4 wheels over the winter months. My plan is to replace the 2 existing summer tyres with cross climates when there tread gets low. I've now don't about 12, 000 miles on the cross climates and they still have 6mm tread left, I'm very impressed with them.
Looks like you have a vauxhall like me with this unusual size tyre. I shopped on camskill and got my tyres £49 delivered each and another £10 each to get them fitted. Just look for fuel efficiency, wet grip and noise. They had a treadwear of 400 whereas the Michelin's before had a treadwear of 240. So these will also last longer. Not had any problems as yet with these budget tyres. Hope this helps.
Older cars? Eg classic
You get a great deal, only £164.22! OP should also include this in the title for good measure. We are struggle with calculators in 2018.
