Another dissenter, Pete.
My Polaris has light grey tubes, and will go from sagging to too-hard with the heat of the northern California sun.
Which is nothing compared to trailering the boat from the SF Bay area to Lake Tahoe (sea level to 6200 ft by way of an 7400 ft pass.) First had to stop a couple of times int he central valley, as temps soared to well over 100F (from about 70 at home), then about every thousand to 1500 feet as I climbed the Sierras. Topped the pass, and had to stop a couple of times to put enough air in to keep the tubes from flapping in the wind. Reversed on the way home (except it was night, so central valley heat wasn't an issue.)
