your'e right. Look at these 2 pictures. the first picture shows a (*)BMW? behind Supersport, but if you look at the track on the second picture it has the same trackpattern as the K1 Ferrari spec in the thread in my link.
when i look at the picture here i see that the trackpattern on the M5 looks the same as my tires.
Does it mean that the trackpattern doesn't necessarily mean that its a ferrari spec tire?
