spirited miles
I had 2005MY R53 CooperS with around 200HP (open diff). Firstly I put Dunlop Sport Maxx on the car. The tires did not grip anything, no dry or wet grip. Simply nothing. The steering response was mushy. The tire was progressive though, predictible at limits. I hated them after 1000miles or so. Then switched to Pirelli Pzero Nero. When Pzero is cold it felt exactly same as the Dunlops. But when it is warm enough the dry traction was better than Dunlops. But still the tires were not giving laser sharp steering response that I was looking for. I belive this is due to the side walls being soft. Still lots of wheel spin, unexpected liftoff oversteers in the middle of the corner - managable though -, understeer in the long corners under half throttle...
Now I am driving a 2009MY JCW. The previous owner had the factory Dunlop ROF tires when I bought the car. It was the first time I drove with the ROFs so the first thing I noticed is the unbeliavably quick steering reponse. the tires were 2008MY, mostly worn and cracked. But the grip, steering response was far better than the Pzero's on my previous R53. I was completely shocked considering all the bad reviews I have been reading for the ROF tires for years. But the ride was unforgivingly harsh so I changed the tires to Pzero's again since it was quite cheap - making the same mistake twice. What I experienced on R53 came back to my R56JCW. Understeer, mushy steering wheel.
The credit I give to Pzeros is the soft ride, progresiveness at the limits and tire wear. What I look for in the tire are the ultimate grip, hard side walls (not ROF hard) to give sharp steering wheel response and high centering feel on the steering wheel. Next time I will be going for Bridgestone S001, RE002 or Michelin Pilot Super Sport.
