R compound never grip well in wet, the Re55 has big improve from re540s in bad weather, but it's nowhere near the word good
as ad07, Re01, re01r are not available in Aust. (unless import)
if u want grip in wet u will need street tyres like potenza s-03, michelin pilot sports, dunlop fm9000s
michelin pilot sports get my pick, grip well, but the most brillant thing is thier low noise and ride quality compare to other tyre with similar grip, u pay for it tho
