I am running the Nitto Invo tires with the stock 19 inch V rims. The Max PSI on the tire says 50 PSI. How much should I be running for daily driving?

I run 35 but I just like the firmer ride. 32 is perfectly fine.

Look on the door grasshoppa. It never lies ;)
Yeah but he's talking about non-stock tires. I'm running the pilot super sports, at ~40 psi warm for winter. Max on these tires is 50, min is low 30s I think, so I don't like running them too close to 30. When they're cold they're down at 35, even filled with nitrogen.

I run the pressures noted on the door, but I run a mix of about 78% nitrogen and about 21% oxygen. Pretty inexpensive compared to 100% nitrogen
