The 3R seems to be designed in a way that handles the weight of the ZL1 much better than other tires like PSC2 and NT01, even with those in 305/325. PSC2 and NT01 are GREAT tires, on other cars--like Porsches. Not on the ZL1.

I recommend you get those Apex wheels and use the 3Rs, the ZL1 also needs a lot of rubber so having 11/12 wheels allows you to run 315-f/345-r on ZLE, maybe not on ZL1. The car especially benefits from the wider tires when running brand other than GY 3R.

3Rs are also less expensive than NT01s.

Agree completely
