UKZR1-
The original post was asking about the best tire pressure for the GY F1 tires. ZR-1 Franz did say "As the ZR-1 DRIVER'S MANUAL says, inflation can be reduced, from normal 35 psi, to 28-30 psi." I was more or less responding to that, and what happens when you do. Your post talked about having run 32 psi in the UK, then at the end you mentioned outside tire wear. I mentally combined the two sections not connecting the 35 psi portion, and just added it to my post, My Bad!
