testing on warn rain tires?

[johnny shell]

notice in some of the testing pics it looks like they're testing on slicks? except the tires have a faint rain groove patter in them that looks like it's completely warn away?

what's up with that?

There's 2 types of rain tyres, for heavy rain and for light wet conditions. Those in your pics are for light rain, and they have been similar for years.

lighter rain

Taking into account that Ferrari alledgedly lost the WDC because of bad management of intermediates on a drying track (was it Hungary?), it sounds all reasonable that they are testing in those conditions.

That teams should try to be ready for everything that may happen along a season. A situation where several races were won or lost in the last few years has been the situation where rain stops and the track starts drying: how long do you stay on the degrading intermediates? Wrong decisions and/or luck in those situations have defined several races, and you might end up needing those points at the end of the season.

Your first example is a normal dry tyre, nothing wrong with it at all. Heavy rain tyres seems to make, when photographed with a slow shutter speed, the tyre look like a dry tyre but with one extra groove, five instead of four (front tyre). If the car was stationary the tyre would look like this:
