Sitting around thinking about how the car drove since installing the 315’s, I started to research recommended tire pressures for the street. Soon, I realized I had no idea how much pressure was in them. Grabbed a pressure gauge and headed to the parking lot. My findings: 38 psi in the front pair and 36 RR + 24 LR
Went back to the shop, grabbed an air tank and proceeded to set the tires to 34/30 cold.

After work, I hit the curvy road following the Mississippi River levee to gauge the results of my efforts. After several miles of driving, to put some heat in the brake pads, I turned up the speed and aggression. Quickly figured out that I could put power down much sooner than before. Started dumb shit like shifting down to second then going WOT post apex and they just ate it up.
What I liked the most? The fact I could downshift to 2nd then take 90° corners (ie turning right off a highway onto another highway) and actually power through the slide without the tail coming around. Lateral traction is so much better than the Federals.
The last hard turn I attempted was the decreasing elevation “clover leaf” exiting a bridge. My entry speed was around 50 and I pushed it to 65 but never once felt the tires ready to break. Perhaps that’s a bad thing on the street but I didn’t want to push my luck beyond that.

Can’t wait to see how they act in the cones!
