2015 FLRT right Rear tire wearing more than left tire

[rhino 2]

All three of my Triglides with the stock Dunlops the rear tires all wore evenly and one of them a 2011 I put almost 50,000 miles on those tires..

I guess I always thought a right tire would wear more quickly on any vehicle with an “open” differential, but this is my first trike so maybe not. It would be interesting if others (with a depth gauge and more than 15,000 miles or so) would measure and compare. Helpful hint. I kept my phone handy while measuring in case I needed assistance getting back up.

Why would a right wear faster on an open diff?

My understanding is that, on cars, under acceleration, the pinion is “climbing” the ring gear and twisting the axle assembly up on the right and down on the left. When that happens the right tire unloads you get wheel spin, aka “one tire fire”. I could be way off base especially on how this would apply to trike differentials.

It shouldn’t that’s why the OP is questioning it…

On cars with out positraction and enough horsepower to do burnouts the power goes to the wheel with the least traction and that tire will wear sooner….Tri-Glides don’t have that kind of power to do burnouts …..
