People can choose to use what ever unit they like. Last time I looked ny tyres were metric. That could be converted to French inches if some one wanted to but they would still be metric items.
Have you checked they are actually 15" or 17"? Or is it just convention like 3x2 timber, which was never 3" by 2"?
When people buy self service loose they take a number of items not a weight. If a pack they look at the number and quantity in them.
The fat sausages are a bit of a problem, 2 for me and she will just want one. 2 fat is more than 3 slim weight wise.
Like some other items they could be imperial but that doesn't really matter does it. The fit of the tyre is the imporant area and that is unlikely to be a simple imperial size so tyres finish up being specified in metric to some agreed standard that tyre manufacturers meet. Actually I don't think I can recollect buying a tyre to an imperial size. I can recollect some rather strange conversions when timber suppliers sort of went metric.
You must be a youngster then. Crossply tyres were imperial sizes.
Anyone who did Nuffield Maths at secondary school (progressively introduced at an increasing number if schools from about 1961/62 onwards, I believe) would have done both. By the early 1970s Nuffield was pretty much universal, again from what I've been told. I'm glad I did it, really - it made other subjects like physics, chemistry, woodworking (I did a bit of that in Imperial and detested it - but then the teaching was absolute carp, delivered by teachers who didn't give a stuff, had little feel for the subject and had zero patience) and metalwork far easier IMHO
And the engines in cc .... or even horses!
Maybe I never bought a car that used crossply. Or even just not fitted with them when they could be. 1st one was one of these, used, cheap and a coupe which I sprayed bronze yellow with a matte black roof -
bad idea as it attracted the police. Plenty of driving foot flat to the floor when possible and friend bought it when I sold it. Bit annoyed with me - maggots spilled in the boot and thought I had removed all ;.
The original rotboxes! At least the chassis could be repaired easily, a bit like Landys. A mate had a Vitesse saloon at one time - went like stink in a straight line (2-litre straight six), but absolutely carp on tight corners. A real Q-car - he crunched the bonnet and the only replacement he could get from a scrapper was the Herald one (Vitesse's had twin heads) - so it looked like a Herald but went more like a GT6. A genuine 2-litre Cortina eater. I used to race him to work in my Spridget (1275) and only beat him because I could corner a lot faster. Early to mid-1970sTriumph Herald - Wikipedia

No rot problems and it must have been oldish when I bought. Usual suspension bolt problems though. Twice. Once on the front so changed both and once on the rear part way back from London but got me home with rather splayed rear wheels.
One side rather strange from memory. A slab in the boot improved handling.
