Winter Storage Question (Tire Pressure)
For those of use that have to store our corvettes for the winter, what tire pressure are you using for winter storage? I am using 40 PSI. Thanks!

If you aired your tires in the summer you will need to put some air in them for winter for sure. You will loose about 1 lb for every 10*F drop in temp. Using nitrogen will cause less air loss and reduce the moisture in the tire.
I put mine away with 38 psi sitting on soft pads. I live in Michigan. In the summer when the car comes out of hibernation I readjust the pressure to suit the season.

What ever the pressure was when I parked it for the winter is where it stays. Since it's not moving anywhere it's really not an issue..
If you're thinking about flat spotting tires that sit for months at a time, that's not an issue with radial tires.... Flat spotting tires is a thing of the past from the old bias-ply days.

My C4 sat for over a year and has flat-spotted the tires. I have to drive 10-15 minutes on the highway before it stops vibrating.

Hi Glenn. I have to disagree with you. Radials do flat spot. Working at a dealership, I see it quite often. Especially cars that sit on the lot unsold for quite a while. It usually doesn't happen just over a few months, but it does happen.

WILL NOT HAPPEN...
When a bias ply tire would flat spot, it was done (flat-spotted) forever.

Again, I have to respectfully disagree with you Glenn.
I've been at my dealership for over 21 years. I'm in the business and see it every so often. It's a myth that radials can't flat spot. I have replaced many sets of tires for flat spotting concerns. It can be temporary but some do need to be replaced. I have a Hunter Road Force balancer at my shop, and some tires can be quite severe.
My C4 has flat spotted tires from sitting. It does go away after driving, but is a major annoyance.
For what's it's worth, this is a link to TireRack's website tech section. I would consider them tire experts, since they do their own in house testing. And they are not talking about bias ply, they don't even make them anymore.

A quote from that link:
The longer tires remain stationary, the better they remember the position in which they were last parked. Tires on vehicles stored on the ground for many months can be permanently flatspotted.

For me (no, I don't store my DD C6) it would depend on whether or not I put it up on blocks to let the suspension relieve or not. I say that not knowing if a C6 is appropriate to leave the suspension hanging unloaded (some cars aren't).

You don't have to put it up on blocks for the winter, just add a few extra PSI.
I didn't mean to scare anyone, just stating facts.
Tires usually won't flat spot over just a few months. If it's sitting for closer to 6 months or more, well then...........
