I have a recumbent tadpole trike (though maybe this would apply to any style). Its two front wheels have a few degrees of inwards lean. The rear is of course perfectly vertical.
I've read in another question that for bicycles its not generally needed to rotate tires, and that any uneven wear may not matter much.
But on a trike the tires aren't changing their angle to the ground... and I think all three would normally wear differently.
Should I rotate them? Or reverse them? If so, how many miles would be a good rule of thumb?
Would the answer /advice be any different if there was no inward lean?
