How to measure wheel offset
Couplemate has 2 IRS Experts. In this video, Bruce explains how to calculate tyre offset. This is a critical measurement to prevent the tyre from hitting the chassis.
* All axles are available unbraked or with the brake options as shown.
** “Unloaded” refers to the chassis being supported and suspension arms hanging free.
*** Nominal suspension travel is 50mm at design load & a further 40-45mm at bump
Shock Absorbers are also available.
