my opinion on it is....if you are going to mount a rear on the front for going "double dark", don't reverse the tire. Those treads were designed for a certain rotation mainly to help in the removal of water from between the road and your tire. Water is pushed to the outside of the tire. If you reverse the tire, water is pushed into the center of the tire adding more water between your tire and the road.
Hey there. Thought I would quit lurking in the shadows and give shout. I am running double-dark and have been for some time.On my Wing I ran my first Battleax BT-45 in reverse rotation and it performed well for 24,000 miles, but showed some cupping in the last 4-5,000 miles.The second one I put on in regular rotation - with the arrow. It is now at 21,000 miles and looking like it might make 30,000. However, I also have been running it with 2 more psi than the first and improved front suspension just before the tire swap.Find a pair of ME880 for a Goldwing, front and back. Look at the tread design and you will see that they are identical, just reversed tread pattern between the two. Thoughts are this: Rear is supposed to shed water and hold best under power. The front tire is supposed to shed water and hold best under braking. So, some spin that rear tire around and run it reverse rotation.In the above 45,000 miles I grabbed a handful of brake more than a few times and rode a few twisted roads in the rain while pulling a 600 lb trailer. Forward or reverse I never had that tire try to get out from under me. IMHO, you can go either way. With the right tire it will work great.Battleax BT-45 on the front Michelin Primacy Alpin PA3 Run Flat on the back. Plain-Jane Wally World on the trailer.
