Incorrect. They do make a 285/30/20 in R888R as as a 315/30/20 which is the perfect size for the 5th and 6th ZL1. Several members running them in those sizing. You can see them on their website, toyotires.com.
R888Rs will hook decently well, but no 20" tire will dead hook in 1st or probably 2nd with 700+ RWHP on a 305/315. An 18 or 17 would be much better off. There's 17" wheels that clear the brakes without having to screw with the fantastic brakes on these cars. An 18 preserves aesthetics a little more than a 17 IMO as I don't really like the super small wheel/tall sidewall look.
