Rally cars are registered to drive on public roads. Obviously they need to have sufficient tread depth. On the sidewall they say competition use. However, unlike slicks they don't say not for road use or similar. So I am assuming they must be road legal. I drove the team rally car from Bathurst to the Southern Highlands and back to Sydney on rally tyres. Oh what a horribly uncomfortable drive that was. The seat was set up for a midget and could not be moved. No seat runners you see. And the seat was also very narrow (because he was also a skinny midget), which was very painful. Then when I got to Sydney this idiot of a policeman has his blues and toots going, when he crests the hill I am approaching on MY side of the road, heading straight for me. The race brakes are stone cold, and do nothing even though I am standing on them. Rally tyres don't change direction well on tarmac, so it was a pretty close near miss. Well, if we had hit I had a full FIA spec tower to tower roll cage with more crossbracing than a plate of spaghetti to protect me. Still, it would not have been pretty. So I think I will be taking it easy on the rally tyres. They just need to work on the rocks and gravel.
