The Plus Six handbook list the following tires:
Standard - Cooper Avon ZZ5 in 18"
Option 1 - Cooper Avon ZZ5 in 19"
First Edition cars - Continental Sport Contact in 19"
As to tire pressures for all tires the handbook states - 28psi/193kPa
When my suspension dropped I tried ever pressure from 22 psi up to 28psi but because the toe-in was changed it did not help. Now back to 28psi with the replacement suspension and resulting correct toe-in. Result - great handling and a pleasure to drive!
