Today i found little bug. When i try hotlap mode i get message :

Warning : Road tyres on rallycross track

But i use hybrid tyres really. Then i tried knobbly and road tyres and get this message.

And the bug is...?

Your are not using tarmac tires in a 100% tarmac track, hence the warning. You can still drive like that (in fact, it's faster to do so in much cases), so I see no bug in here.

That's strange, using hybrids on a rallycross track should not trigger that message

Ok, i understand i get this message because this track not 100% gravel ?
