235

This number indicates that your tire has a width of 235 millimeters.

55

This number means that your tire has an aspect ratio of 55%.  In other words, your tire's sidewall height (from the edge of the rim to the tire's tread) is 55% of the width.  In this case, the sidewall height works out to be 129 millimeters.

RF

The mark of RF indicates that the tire is reinforced.  This means it can handle a higher inflation pressure than a standard tire, which increases its maximum load.

19

The tire size was designed to fit rims or wheels that are 19 inches in diameter.

101

This tire has a load index of 101, which means it's capable of carrying a load of 1815 pounds (825 kg) or less.  A higher number means the tire can carry more weight.  A lower number means the opposite.

V

This tire has a speed rating of V, which means 149 mph (240 km/h) is the maximum speed that can be sustained for 10 minutes.  A higher speed becomes dangerous.
