Why would he say that when comparing the two if the F1 tyre is actually harder?No he does not say harder. He says hard compund.

http://f1weekends.com/post/12070052446/in-depth-tyresRacecar tires use rubber that is much softer than rubber on cars. It is more like a soft rubber eraser than anything else, and very unlike the hard rubber found in passenger car tires.
The racing tyre is constructed from very soft rubber compounds which offer the best possible grip against the texture of the racetrack, but wear very quickly in the process.
It would be easier to get heat into a road tire then a proper racing F1 slick.Otherwise you could preheat a road tyre to it's operating temperature and it would be like glue.
First paragraph:A softer compound basically means more grip. So if you're theory is right, that a road tyre has a softer compound than an F1 tyre, it would mean that a road tyre in its chemical operating window, would suddenly produce a huge amount of grip.
Besides a softer compound always means shorter lifespan.
So a road tyre (which normally lasts around 50.000km) in its operation window mounted on an F1 car driven at F1 speeds would suddenly last less then 120km?! (Let's just focus on the compund and ignore the structure).
Another thing is why should the ideal operating window of a road tyre be at 90-95°C (according to you) when it's driven at approx. 0°-50°C. Why would it be designed to run: a)outside that window all the time b) in a window with a margin of only 5°C?
Coudn't find a source about this but it's just not logical for me
"Besides a softer compound always means shorter lifespan."
ideal operating window is another thing. Producing the most grip is another.Another thing is why should the ideal operating window of a road tyre be at 90-95°C (according to you) when it's driven at approx. 0°-50°C.

All of this makes complete sense. The link to the other forum conversation and the video all lead me to still believe that F1 tyres are a lot softer than regular road tyres.http://www.f1technical.net/forum/viewtopic.php?f=4&t=8100
In a nutshell: F1 tyres are much, much softer.
Edit: Also...
It was good as Pirelli going on aggressive approach.
but i think Australia mostly be a 2 stopper than a 3 stopper.
Why only on an F1 car?Yea, and that´s why a road tire would be turned to mush after one lap on an F1 car instead of a super soft tire.
Do you have a source for that temperature window? Sadly, I couln't find any.90-95 degrees is where the tire will produce the most grip, that´s the transition phase if you will where the tire starts creating it´s magic.
Because a road car tire does not experience temperatures even remotely close to what an F1 tire does, not to mention the G forces.Why only on an F1 car?
If it is that soft, why would a it last 50.000km on a road car, but not even 1 lap on an F1 car?
Not only uses more rubber but puts in way way way more energy in the tire.Of course a F1 car would "use more rubber" but I highly doubt that it would use up that rubber 10.000 times faster, even in the peak performance window.
It's about the construction and not running out of rubber. The main difference here is 1g vs. 4-5g, which is mentioned in the video.
Best is to ask Pirelli again, most tires are in that region. That´s where the rubber starts to transform.Do you have a source for that temperature window? Sadly, I couln't find any.
I think it does, and not even in the same spectrum of scale.I really respect your technical input here on RD Hampus, but there is no way a road tyre has a softer compound.
I hope Pirelli will end this discussion
http://www.formula1.com/inside_f1/understanding_the_sport/5283.htmlThe racing tyre is constructed from a blend of very soft, natural and synthetic rubber compounds which offer the best possible grip against the texture of the racetrack, but tend to wear very quickly in the process.
Well, that is exactly what I was talking about.If you are lucky a road tire experiences around 1G, that´s a huge amount of difference in energy being put into the tire vs an F1 car that can generate 4-5G in lateral forces and 5-6 in longitudinal forces.
It´s a completely different ball game.
Not only uses more rubber but puts in way way way more energy in the tire.
Max 1-2 laps if even that going hard in an F1 car with regular street tires.
And that´s where we disagreeWell, that is exactly what I was talking about.
The forces would destroy the road tyre because of its weaker construction and not because itsrubber is too soft and wouldn't last.
F1 tiers have a much stronger/stiffer construction because of the occurring forces but a much much softer compound to give maximum grip.
Hi, is an F1 tire a harder compound then a regular road tire? Even Super Soft?
No point in comparing the two; it is like apples and pears.
we are talking about the compound.You should've specified, that you're asking just about the rubber compound, not the overall structure of the tire.
