Tire pressure
Should I be filling the tire to the max PSI listed on the tire ? or is there a recommended setting, I know when the car came it was at 212 which seemed really high, they have dropped to about 207 because the car has been sitting for a month and a half.
Cheers !

Say what?
I seriously doubt you have 207 PSI in your Corvette tires. 
Oops, just noted you might be in Canada and I am not aware of the Canadian equivalency to POUNDS per square inch.
Peace, out.

Jamie, you have your answers above as well as the excellent piece about the change of tire pressure (up AND down) as temperature changes. But, one more caution: there is NEVER a reason to inflate any tire on any car to the max listed unless it is either on the door panel sticker/medallion or in the owner's manual.
Each tire model/size is used for more than one vehicle. Different vehicles run at different speeds and loads. And each car has its own set of specifications based on the tire and the car manufacturer's intended load and use. The "high" number on the sidewall is there to show the max air pressure that the tire can safely take, but not necessarily appropriate for your application, the Stingray.

Need to know what kind of tires you have.
If Standard load P-tire the maximum pressure given on sidewall is realy the maximum cold pressure ( when inside temp = outside tire temp = about 18/20degrC/65/70 degr F) the tiremaker allows and varies between 44 and 51 psi( 300 and 350 kPa).
The maxloadpressure thoug is always 35 psi/240kPa ( Eur system 36psi/250 kPa with exeptions to lower.
XL /reinforced/Extraload same story Maxcold sometimes even 60 psi/420 kPa, but maxloadpressure always 41 psi /280 kPa ( Eur system 42psi/290kPa with exeptions 41 and 44 psi).
From C load LT tires maxloadpressure is given on sidewall mostly like this " maximum load xxxx lbs AT yyy PSI ( cold)" , thats why I call this maxloadpressure/reference pressure the AT-pressure furtheron.
I am able to calculate the needed pressure using this maximum load and AT-pressure and the real load on the tire. Also need maximum speed of tire and the maximum speed you use and wont go over for even a minute.
When I read Corvette I think speed will be high.

Just some input of what I have decided to do.
I own a 2015 Corvette Stingray (base model) with 19" front and 20" rears.
Due to the extreme temperature changes that we see here in the deep southwestern area of the USA (New Mexico) I have chosen to run my tire PSI 3 lbs over the suggested limits recommended by the owners manual or what is listed inside the drivers door sill.
We can have temp changes from daytime to nightfall of 20 to 40 degrees. I have found if I keep the cold temps at the recommended PSI (30 psi), when viewing the TPMS readout of PSI I was getting 27-28 PSI cold.
Keeping the tires slightly overinflated I now get readouts close to the recommended PSI. I cannot attest to the exact accuracy of the TPMS on the digital dash readouts.
Weather temps will make a difference, and it may be doubtful that many areas of the country (USA) will not get the vast differences that we encounter here in southern New Mexico between daytime and nighttime temperatures.
This process of slight over-inflation works for me.

And that is a wise thing to do for your area^^^. As one tire engineer said a few years back, to paraphrase, he'd rather see a tire that's slightly overinflated than one that is even a couple pounds under. When asked why, his response was because when he sees one underinflated, it's usually because the owner is not paying sufficient attention to tire pressure and it could go much lower and the owner wouldn't know it. The results of a very underinflated tire could be tragic.

I go with slightly over inflated with winter coming up, so if the temperature drops the tires still have at least the minimum cold pressure of 30 psi. As stated, better to be a little higher than lower.

After warm up or when they get hot, on a car tire you can expect a 3 to 4-degree temp change on the dash readout.
A lot depends on the geographical location you are in. A car located in Phoenix will show higher temps when hot vs cold vs a car in the northeast.
Here in southern NM in the summer months, I can get readouts/temps of 5 degrees over cold tires. The roads, especially asphalt get quite hot with the sun beating down on them.
