Tire Pressure

[Jeremy '95 Viper]

I have a 1995 Viper with the OEM wheels. Just put Pilot Sports on. What is a good tire pressure for the road (i.e., spirited canyon drives)?

Also, can someone briefly explain the effect of tire pressure on handling?

I believe it is 29psi for the Gen 2 cars, not sure about yours. I think you are safe at 30 either way.
Lots of good tire info over here:

29 psi is the best for track and street.

Thanks!

Dan -- awesome to hear from you! I was actually back out at Willow Springs last weekend (not in the Viper, though).

On my 94 RT my pressure is at 33psi. Works well for me.

At 30 PSI, Gen II seems to follow every crack and road imperfection. The higher I run the PSI, the less it seems to do this. Anyone have some insight into what PSI would limit this type of road response?

Michelin Pilot Sport is designed to run at 29 pounds cold.
If you run the tire at higher pressures you will wear out the center of the tire - you will be surprised how quickly.

Road Response - you are kidding - you want this to go away?
I don't get it? Isn't this why folks drive Cadillacs?

29psi, I did not know that! I was told 32-33. I will lower mine to 29psi, thanx for the input Gavin.

While we are talking about tire pressure, can someone explain the tire pressure monitoring system that some of you guys are adding? Ease of installation? Cost?
Thanks
