I wonder if it might have had something to do with the entry angle from your driveway to the street?Hello BKL
I had the restricter chains set to the same as the one pictured. This was actually too restricted as I had removed the aluminum strip on the cradle and added 80 grit tread self stick strips. On the very top of the cradle where the ratchets are mounted, the tire had turned a little further than the cradle, due to the restricted chains. Just so you know, this was a standard RH turn from my driveway to the street. I even drove into the other lane. Still waiting on 2” wheel spacers
I'm still hoping to get my Slingshot back on the road soon and hopefully finally get to try using the tow dolly on a test run.
Do you have the "curved" tubing instead of the angle iron between the front and rear of the cradle? I have the early design that just had a smooth cradle. Good idea about the self-stick grip tape.
Good luck resolving the rubbing issue.
