Just what the title asks.
The parking lot at my office is prone to light flooding after a good rain, and my car will typically be parked in a shallow puddle for a few hours (I drive home for lunch, so it's never parked more than 4ish hours at a time).
Is the standing water bad for the tires? Do I need to strategically be searching for a parking space on high ground?
If water does not reach the bottom of the wheels, the car will be fine. As another answer says, getting tires wet on the outside is not an issue.
If water reaches the bottom of the wheels, try to move the car to another spot. Persistent immersion in water can wear away wheel finish over time, and water can cause corrosion around valve stems.
Vehicles generally prefer a dry environment, but if the air is humid it doesn't really matter whether the vehicle is over a big puddle or not at this point as air humidity does more damage than water under the vehicle.
The tyres are waterproof. They will not be harmed by getting wet.
Actually, it depends on the temperature of the puddle. Especially if you have old or profile tires, the cold water can speed up the process of deflating your tires. I live in the Canadian winters of Hamilton Ontario where I keep many cars on the lot and I make sure not to leave any tires in puddles overnight. If it's for a few hours in the day and the water isn't cold than its a different story and should be fine, like the others said so long as the water isn't getting inside the rims. The main concern should be the cold though.
