Where to put new tire on a front wheel drive car?

Usually a new tire is replacing an old one and as such is actually going to replace that.

If you mean rotating a new tire into the mix generally it goes on the Left Front, regardless of what drivetrain the vehicle has. For best instructions, the owners manual or a mechanical journal will have a chart for your particular vehicle.

In general to replace a tire, you jack a car up by the supporting frame next to the tire you are replacing, you remove the hubcap if there is any using either a screwdriver or the appropriate tool if your car has a hubcap key. Next the bolts holding it on need to be undone with a tire iron, and the tire removed. The new tire is then put in place, and the bolts are restored using the proper torque (or just slightly snug if you don't have the available to tools to ensure proper torque), and the hubcap should snap back on afterWords.
