Track tyres are just that, track tyres, no hard or soft option for them, (ok for rain as well).
Some other cars only have a slick option, not soft or hard slick, just slick, (you get a wet tyre option though).
I'm just about to upload a video driving the Ford MkIV @ Vintage Le Mans, like your car it only has the track tyre option but they're fine in all weather (apart from huge puddles in a thunderstorm) but I still survived (just) & they last quite a bit as well.
