Race drivers will always complain about their tires. Its the nature of the beast.
The Proxes TS-1 is a street tire that's being used for racing and, as such, its OK but a driver has to be very careful and not use the tires up early. The Proxes RA1 is built on a race tire carcass and a can handle more abuse. Unfortunately, Toyo wanted to promote the TS-1 so that's the spec tire for the WC series.
