When I Purchased my Z3 in 2010 with worn Dunlop ZI's (255x40R18 Front & Rear) the front wheels rubbed the inner wheel arch on full lock, so I changed in Feb 2011 to Dunlop ZI's (Front: 225x40R18, Rear: 255x40R18) with no rubbing. They were OK, but I wanted better. In Nov 2012, I changed to Toyo Proxes C1S (Front: 225x40R18, Rear: 255x35R18) and found them about the same as the ZI's, OK, but nothing special. Then in Nov 2013 when changing from 18" M3 wheels to 17" Wire Wheels (for looks), I did more research as I wanted the best dry tyre (not too concerned about wet performance as seldom drive my Z3 in the wet) and got a set of Dunlop Direzza ZII's (Front: 225x45R17, Rear: 245x40R17) & Wow!, These are the ones! ...in the dry, there are like glue ...almost like slicks ...very impressed. Have not tried them in the wet though, but are said to be OK. They were about the same price as the ZI's & the Toyo's but much better. They are the best dry road tyres I have ever experienced. Period. Cannot comment about wear yet, but seem OK so far... (Picture: R18 Toyo Proxes on the Z3 in the background, Foreground: Dunlop ZII's on the new R17 Dayton Wire Wheels)
