Tyre experience over 9 years of driving Zeds and in company with many other members on many drives over those years:
040's - utter rubbish, unless you like to drift most of the time.
050's - a lot better, especially in the wet but...........
452's - good fun and for road use with pressures upped to 38psi, but..........
VUS - these were good, great fun but of course they wore out quite quickly. I also found in Wales last year by following others and buying them that:
MPSS - are clearly outstanding in comparison in all departments aside from road noise and for me are the best tyre for Zeds so far
