 Unlike the tarmac tyres we may use on the track or even the family tyres on our car, the KUMOS and the Australian Rally Championship are very specialised, however we do have two types to try and optimise their performance despite the conditions. We've got them both here and are 800 and are 900. The main difference is the construction of the blocks. So they are 800 designed to try and take advantage of the first pass or the first run we go through or wet conditions, just trying to fight through the top layer surface and get down to the grip below. You can see there's quite a bit of a gap between the blocks. If I even turn them there they squirm quite nicely trying to bite down and take advantage of that. On the other hand if we do a second pass or getting very warm we may use the 900. So even though it's still a medium you can see we've got bigger chunkier blocks trying to really just take advantage almost like a circuit but it's hard packed you can bite down and take the most advantage of that. You can see even some of the the blocks are linked together so that we don't get that same squirming effect and we get better driver feel. The good news for us at home is the lessons learned here from the Australian Rally Championship for motor sport like it are taken advantage of the road types produced by the engineers at Kumo.
