Default Turn Front Wheel Around?

I am running a BT-45 on the front of my ST-1300. It is starting to cup. Is there any reason why I can't remove the front wheel and turn it around to try to reduce the cupping? I presume the wheel/brake disks are symmetrical.

Isn't the BT-45 Bias and directional?
The ST's wheels are directional.
Look at the right side of the wheel.
All three spokes have a direction arrow.

What tire pressure are you running on that tire?

Isn't the bt45 meant for smaller lighter bikes?

The front wheel can't turned 180 degrees. It only fits one way.

Cupping could be prevented by inflating the tires on an St to 42 psi.

Yaesu has gone "Double DarkSide".

The BT45 is a Rear, Bias Ply tire designed for older motorcycles. It does work in this application, I have seen it.

It is actually one size larger than the recommended radial front for the ST.

I do not wish to rekindle the argument over the DarkSide or the Double DarkSide, I am just providing information.

To try to answer the OP's question, I just do not know. The direction of rotation of your BT45 was based on it being a REAR tire and the tread pattern reflects that. IF I had ever run this tire on the front I would have turned it backwards from the beginning.

Very few folks on this forum have any experience with what you are doing so I would be surprised if you got any useful answers. And I have to wonder if the tire is cupping if it is really worth the effort to go to a nonstandard tire. Only you can know that answer.

If your running oversized non-radial front or rear tires your suspension setup is critical.
A oversized rear puts a hell of a strain on the front so the front end suspension must be adjusted accordingly.
Fresh fork oil first and you may need to adjust it's weight slightly higher.
I would not mess with anything under 8 weight and would consider 10 as my starting point.

I would not simply turn the wheel around as it is designed to run a specific direction as indicated by the arrows on the spokes.

You need to seek out those with a ST1300 that are running non-standard tires for advice.
It must be ST1300 simply because of the rear wheel size.
All of the other bikes running car tires have a wider rear wheel than the ST making ST1300 specific your only real choice for advice.

Id say if you are running a rear on the front, the tire in theory will be running backwards. If so, you are happy to be in unknown territory by the manufacturers of both bike and tire so using that logic why not try it.
Personally I wouldn't but as above that's my opinion.

Why would a rear tire mounted on the front rim be running backwards? Would you not just mount the tire on the wheel so that it is turning the correct direction?
