im not sure how people are hydroplaning in their Z's. ive tested several different tires on my Z already in a downpour at 60mph + i could not get the car to hydroplane. 36psi. factory RE050A's were fine, DW's are fine, YokAdvans are fine.
same deal with my G. ive had that car for 9yrs now, not once have i felt her hydroplane. ive driven it through heavy rain too on the expressway. S03, RE050A, S04, Pilots, etc. and even icey conditons using LM60's.
either their tread is low, psi is setup wrong, suspension is setup all wrong, using cruise control in the rain, etc.
