Hi Gareth,
Apologies in not replying earlier - on hols still and wifi is hit and miss.
Agree with what you say about driving style. I tend to get on, but always in regards to traffic and weather. Grew up in NE Scotland, so used to bad weather. Norn Irn has some lovely roads, but some of the drivers can be erratic to say the least. You could be driving at 60 on a damp road, and some idiot pops out a side road, misjudging your speed. Had it happen to me a few times. To that end, I fit the best tyres I can, so that I can stop or at least slow down enough.
As for the 5th Gear segment, I think it was a neutral test, ie not sponsored by any one brand. Budget tyres do have their place in the market, of course they do. But given that I don't hang about, I prefer to have as good a tyre that I can fit.
Given the power in the Jag (near 600hp through the rear), it has Michelin Pilot sport 4S fitted, but rarely gets driven in the wet. If I do, then I slow down accordingly. The Audi is the daily and will be driven throughout the year in all conditions. Last A4 Avant had them, and when we had a patch of snow, the Cross Climate 2s handled the snow with ease. I am used to driving in snow though, but was really impressed with the Michelins.
