Tyres

I replaced my OEM yoki's at 5000 kms with Kumho KU36:

Front: 235/40R18
Rear: 275/35R18

These are a ripper tyre, quite soft - excellent dry grip and good wet grip, yet have provided reasonably good wear as they have 20000klics on them and have endured 3 track days.

They have 2mm of useable tread left - will maybe get another 4-5000klics out of them *(or one more track day).

In terms of replacing these, I was going to try the Dunlop Direzza SPDZ01 but will have to use the 245/40R18 front as the 235/45R18 is way underspec on load index.

Indeed, load index is a real problem with the 370Z as only the OEM Yoki and the Kumho are laod-index compliant ... everything else is a minium of 1 under specified load index, which technically means the car is not compliant with its ADR certification (which means plod can legitemately give you a hard time if he wants to).

I can recommend the Kumho and they come at an attractive price, but will know in a few months whether the Dunlop is a better tyre or not.
