Dual Wheel Spacing

Yahoo Message Number: 83997
I thought that I would try this question one more time. Surely someone must know the answer.
Does anyone know how to measure what the actual dual wheel spacing is on a coach? Various tires call out a minimum dual wheel spacing for particular tire models and sizes and therefore I would like to know how to actually measure this dimension.
Thanks, Steve B

drive your coach on wet pavement to dry pavement in reverse with the tag up. Measure between the tread tracks. Also measure from the center of the tread track to the center of the other tread track and that will give you the distance between wheel centers. Then using a plumb bob measure between the bulge of the tire to the edge of the tread. Double that distance and subtract from the spacing between the wet tread marks in the center and that will tell you how much space is in between the tires. If you have a tag axle do the proceedure with the tags up. This should almost be your worst case scenario.

Have you tried presenting the question to a Google search? Google is pretty smart about these kind of questions. Ask it as a question like 'how do I determine the measurements of dual tire spacing' ?

Steve,

Google is your friend.

Take some masking tape and put it across the face of both treads. Unless you have room in the fenderwells, you'll have to do this near to the ground.
Next, mark the centerline of each tread. Measure the distance between the 2 marks - and that is the dual spacing
