That's the thing. You're imposing YOUR view of things on other people. You obviously like to drive your car enthusiastically. That's your choice and I've no issue with that.
I like to push my car sometimes, but as I'm fully aware of how the tyres will perform I'm not going to push them. I don't tailgate, I don't drive quickly around blind corners where I'll suddenly need to brake if someone is on the road. I drive according to what I have under me. When I was driving a work van it was always easy does it. When I'm in my 500 on the moors with summer tyres in the dry on a warm day then I'll happily chuck it into corners as fast as I dare.
Tyres are never compromised as such, they're only compromised when the nut behind the wheel asks too much of them. Hence why people can have crashes on winter tyres in the winter whilst others on summer tyres can get home safely. My Fiat 131 (my first car) had something rather skinny like 135's or 155's on it so I think I can safely drive on 175's on a 500 with ABS and far better tyre technology with 10 years more driving experience.
You might think that 195's are not enough for something heavy like a Bravo 165 multijet, but consider this..... our Subaru weighs 17kg's more and has 35bhp more than the Bravo an its winter tyre option is 185/65 R15. Is it not conceivable that people could happily drive within the limits of the tyres fitted to their cars? Is it inconceivable that GrandyGuy's missus never breaks 70 on the road and likes to slow down for corners? If you want to raise the bar further then fine, that's fantastic for you, but rather than questioning others as to why they've bought what they've bought, try to understand that people simply have different requirements to yourself and they buy according to those requirements.
We're not all RobW's and we're not all 306maxi's either, thank god for that on both counts.
Also.... Continental's opions on tyres > RobW's opinions on tyres......
