Calmly pull over into a safe place (signalling) and if safe to do so, jack up the car and change the wheel with the spare.
The first thing to do is pull over immediately in a safe place if you are driving. You should then get out your car jack and spare tire and change the flat. It's always good to keep a can of Fix A Flat with you also for quick fixes.
Check it. If flat, replace. If not, keep driving till it does.
A tire cupping can be caused by tread being lost. A tire cupping means that it should be replaced as soon as possible. You do not want a cupping tire to be used while you are driving. Air can escape and cause a flat.
Of course you can, if you are a total nutcase...
Maybe a mile or 2 to get you to a place you can get a spare. Driving on a flat tire can cause damage to the wheel and possibly the drum and brakes. If you must drive on a flat tire, drive very slow and stop if the tire comes off the rim.

You could have blown your tire or it could have gone flat.
It could be badly out of balance, or it could have a "flat spot" from broken cords inside the tire. And it may not be the tire at all - it could be suspension system parts.
An all terrain tire, or a sand specific tire would be best.
Two things could cause the tire to make a noise sounding like a flat tire even though the tire is fully inflated. First, if the tire has a big enough flat spot on the tread surface and second if the radial plies in the tire have separated letting air between the belts causing patches of the tread surface to bulge.Answeri test drove a geo that had loose lug nits on it that made a noise like that
Tire pressure should be adjusted after a period of driving. The air in a tire will heat and expand as you drive on it. Therefore, to prevent overpressurization, tire air pressure should be adjusted only after a period of driving.
Rear tires, bad leaf springs if your car has those. I have this problem. Can be defective shocks or struts, bent wheel, tire out of balance, flat spot on the tire, or another defect in the tire.
