My tire pressure light is on and the gauge is telling me that my tires are

29 (Top#) /33 (bottom#)

on the front and 28/33 on the rear. Does the top number mean the right side? I've searched and searched but I only find descriptions on what the tire sensor does.

Any help would be greatly appreciated

 

You can check the pressures and match them up...

 

true. did it and left is top and right is bottom

 

Moving to wheels/tires section

 

On older cars you can never tell if somebody has moved sensors around so it's always a good idea to check them out manually to establish the L/R assignments.
