Hi I am not going to be much help because I have only done around 200 miles on a set of 13" ZZS but I can say I already prefer them to CR500 [dated 2012, so not an old knackered set]. I have not played around with pressures yet, just set them at 18psi as per previous, also not run them in the wet. What I can say is that they hold on a lot more in the corners in the dry straight from the off. Plenty of feel, nice and compliant, look really cool too , certainly feels more pointy at the front end. ZZR must feel better still than the CR500? No experince with any other tyres, have you looked at the Toyos? ZZS and ZZR would mean perfect setup for both types though. Cheers, Julian
