I just put on a set of PS4S' and am very happy with my choice. I live in Vegas so weather and roads are similar. I considered the cup tires but for a daily with limited track time and a desire to get a little more distance out of this set I decided on the PS4S. Good luck with your decision.

ok judging from this thread mine are definitely over inflated. Im at the factory's suggestion of 34 front and 45 on the back?...
Everyone seems to be so much lower here... Also dumb question, how do i properly deflate the tires? And it seems like 32-34 is what they should be inflated to?

Comfort: 29F, 31 R @ 68˚F
{Normal: 31F, 37 R }
Normal CTP will give you a very harsh ride.
All CTP is assuming 68˚F ambient temperature.
You need to adjust your goal CTP based on the temp.
I use 30F 32R in winter (I'm in AZ)
I use 32F 34R Summer
Now it it 107˚ so I will bump my CTP goal to 33F 35R
I like to have the TPMS show +/- "0"
I have Michelins.
"The rule of thumb is for every 10° Fahrenheit change in air temperature, tire pressures will change about 2% (up with higher temperatures and down with lower)."
