That is an incomplete tire size description. The complete description might look like one of the following:
P245/45R18 96V
245/45R18 96V
245/45R18XL 100V
The differences between them are their load carrying capabilities (how much weight they can handle) at specific pressures.

That describes the following about the tire:
The tire is 245 millimeters wide.
The sidewall profile is 45 percent of the width or approximately 110 millimeters high from the bottom of the tread to the edge of the wheel.
The R simply means it is a radial tire.
The 18 is the size of the wheel onto which the tire is mounted, 18 inch wheels.
The V is the speed rating for the tire, that is, the maximum speed at which the tire can safely be driven, in this case 149 mph.
