Measuring Backspace.
Caravan & Trailer Tip
Wheel backspace is an essential measurement for the manufacture of axle length. In fact, backspace is so important, Couplemate will not manufacture a new axle without this measurement.
The first thing you need to do when building a new trailer is to buy your rims and types. Alternatively, you could purchase your rims and tyres from us and we’ll do the calculation for you. One more complication, we need to know your chassis width.
