You will get different opinions but speaking from my own personal experience, I have generally found that a Minor behaves better on the road with the correct size of tyre which, for a radial ply tyre is a 145 80 14. The Camac tyre is a cheaply made tyre of that size and best described as adequate. If that is all you want then they will be OK but you can purchase something better if you are prepared to spend a bit more. I didn't like the Toyo 155 80 14 tyres when fitted to my car. The tyre is a little wide for the rim. The car behaved on the road as if the tyres were very underinflated - which they weren't and I didn't feel secure in the car when driving moderately enthusiastically and with a load on board. I changed them fairly quickly for Bridgestone 145 80 14 tyres which made the car much more rewarding and enjoyable to drive. These will be a better tyre than the Camac but are more expensive of course.
Many owners have 155 80 14 tyres fitted because they are more readily available and less expensive. I have another Minor which is used as a cheap runabout and has cheap Nankang 155 80 14 tyres fitted. Although it doesn't behave quite as well on the road, they are perfectly acceptable and I would replace them with the same again if looking for a budget tyre. I prefer them to the Toyo.
There are also good quality tyres available via specialist outfits now, from Pirelli and Michelin. I would expect these to be very good but I have no experience of them. Like so much in life, you get (pretty much) what you pay for
