My Zed has 27600klm up in just over a year and I have just worn out the first set of tyres. The Kumho KU36 I fitted right after driveline break-in (I still have the factory tyres under my house) have finally given up the ghost, following 26000 road klics and over 200 track day laps in 5 track day events at 3 different circuits here in southern Oz.

I got a good price (for Australia) on the Dunlop Direzza DZSP1 so I have 245/40R18 on the front and 275/35R18 on the rear, fitted and balanced for A$1620.

I gave the car a light spanking on the way home (those from Melbourne who are located in NE outer suburbs might know of the Mount Slide junction road from St Andrews to Kinglake West) ... 18 klics of 2nd and 3rd gear "fun" - nothing much faster than 100-110kph but also no straights more than a couple of hundred metres long either ... I suspect it is what the guys in the US call a "canyon run".

In any event, the Direzza seem to have as much or more grip than the KU36, which I rate as an excellent tyre on basis of grip for the money (around 2/3rd the cost of the Dunlop), but maybe not up to the grip level of a true "R-Spec" tyre. It will be interesting to see how the Direzza compares to the KU36 and a proper R-Spec tyre like a DZ03G or R888.

I am at Sandown International next weekend and will be able to do back-to-back lap time comparison as I was at Sandown the same weekend lasy year and still have the timing logs and data logging files .... it will be interesting to see how the two tyres compare.
