I am getting fed up of this b*tching about "my tyre is better than your tyre at half the price", but taking your comment about "only" 7 metres extra braking distance at 62mph into consideration, would you have liked to be travelling maybe 20 miles an hour faster when THIS happened? >>>
Stop the scaremongering.
Even with racing slicks he wasn't going to escape that crash, the car would still be written off and the passengers would be as unhurt whatever the rubber.
7metres of saved braking distance is very rarely going to be a lifesaving difference.
The link in the post above doesn't mention if the driver even pressed the brake pedal - even if the speed was as low as 30mph, the reaction perception distance is 66feet, regarldess of what tyres were fitted.
Assuming you use two identical cars, with identical tyres at identical speeds and they both drive towards a wall, one car is driving at a wall positioned exactly the braking distance away, and the other is driving at a wall which is 7metres closer, then the car which hits the closer wall will suffer very minor damage because the remaining energy in the travelling car over it's last 7 metres is actually quite small, compared to if the car hit the wall during the first 7metres of braking distance.
When the crash happens in the last 7metres of braking the damage is much less because the car is losing the last small remaining amount of kinetic energy (compared to if it crashed into a similar wall during the first 7m of braking)
You will definitely hit the wall if the wall is 7m closer but the total change in velocity is very small, and therefore the injuries are minor and the damage is minor.
The only time an extra 7m of braking distance is going to make a perceivable amount of difference in injury (statistically speaking) is if you are trying to stop short of the edge of a cliff. Unlikely ?
Bear in mind that the 7m being mentioned is in the wet too.
7m braking distance in the wet equates to stopping from a speed of 18mph. if the conditions are dry the equivalent energy lost is the same as for a crash from 15mph.
I am not saying that people don't die at these speeds, only that the survival rate is extremely high and often the car will not be written off.
Of course, the 7m of braking distance could be a life and death issue for pedestrians. But the Alfa 159 already has about the worst pedestrian safety rating. I suppose you could argue that because of that you should do everything you can to protect pedestrians, so that would mean fitting better brake pads too.
Personally, I think spending the equivalent amount of money in the difference between price of the cheaper tyres and the Conti's on advanced driving classes would be a better option.
