Pirelli should be having the asphalt surfaces scans which could be replicated on the rolling road, temp of the surface can be controlled, so what does Pirelli finding difficult? is it that they just don't have the same commitment to F1 as the teams in development? Or Pirelli just using lack of testing in F1 as a political defense for poor tyre technology?
If only tire testing was so simple...
They do have a flat track tire test machine, but it cannot perfectly simulate the conditions a tire operates under on a race car. Sure you can get engine drive torque and suspension load data, but the ambient air temperature is typically not well controlled, surface temp is not usually controlled, and I don't know of anybody that uses scans of road surfaces. My understanding is that common practice is to use something similar to 120 grit sandpaper because it's easy to clean off the deposited rubber between runs of different tires. I also suspect, though I'm not certain, that the machine would have a hard time inputting transient loads into the tire.
To say nothing of the quality of the data that you get from the machine. The data that you get from testing rigs like that is useful, but there are a lot of things the machine cannot simulate. It is not as simple as buying the best test machine out there, and then suddenly you don't need track testing at all anymore. Even with good machines, it's not always easy to get useful information from them.
