After some experimentation I have discovered the cause of vehicles automatically rolling backwards or forwards and, thankfully, the fix is very simple.

 

Firstly, select all of your WheelP## bones and then group them together. Then switch to the Move tool while this group of WheelP## bones is selected and look at the X position for the group, this is the overall X position of all of your WheelP## bones. Note down this number and then ungroup the WheelP## bones, we were only using it to get the X position.

 

Now, either select your origin bone (this should have EVERYTHING, including the worldbox, linked to it either directly or through a chain of links, if you don't have one yet create it now) and choose the move tool. Click on the square grid icon next to the X coordinate to activate relative movement.

 

Now, type into the X field the inverse of the number you wrote down earlier, so if it was -0.512 type in 0.512, if it was 0.245 type in -0.245, and then select the Y field. Everything in your model should move along the X axis by that amount, perfectly centering the WheelP## bones along the X axis. Now you can turn off relative movement mode if you like and re-export your model. It should no longer roll backwards and forwards on it's own.
