If I rember correctly, normal tyres have an aspect ratio of 82%. The /80, /70 etcmean that you have the same tread width, but the profile is narrower, creating a smaller circumference.
These were designed for the 3L Lupo (car not available in UK) which was the most fuel efficient production car ever produced. It did approx 92mpg (100km on <3L of diesel) and came out ~7 years ago incorporating extensive use of new technology. (I worked on some of the transmission auto-shift components).
The tyres were very special to have very low rolling resistance - the pay off is that they have very poor grip!!!
I am amazed to see they have come down in price, but I suppose the tooling is now old and they need to sell some volume before they stop production.
If you're feeling brave, I'd love to know how they felt on a Minor (especially as they are a sensible price) , but there's a risk that you'll not like them as much as other tyres.

Most Minor tyres have almost no grip anyway! And beware - these are only good for 118 mph ! They look great although not the cheapest tyre on the market.
What speed rating do you have on your tyres, BMC? I'd say a T-rated tyre will be absolutely fine for a Minor - 118 mph is >30mph over the top speed, and if it you're going faster then you're not going to be running on 145-section tyres anyway. At least, I hope not.
I have those Bridgestone tyres on the front of my Minor (Bull Motif sell them, I think) and they grip much better than the old Uniroyals.

Is there any difference between the Bridgestones and Firestone? I didn't think much of the Firestones I had on, about as much as the budget NanKang I have on now.
As far as I am aware Viking don't sell them in 145/14
I find the new Bridgestones a tad too soft on corners, maybe I'll but some more air in
