i have a 2016 Road Glide Special that I purchased in March of 2017 I love this bike and put 12,500 miles on it in the first year.
Recently I noticed a little wobble when cornering on the freeway at 80 MPH it needed a new back tire so I had a Michelen tire installed now I have terrible speed wobble at 70 MPH the rear tire was overinflated so I fixed that 40psi in the rear and 36 in the front the wobble is less. I tow a trailer and it wobbles at 60. I read a lot about fall away and other causes. Is it possible that mixed tires or maybe the new tire and old tire are the cause? The front is a Dunlop and has about 40% left. The wobble is unacceptable I need it fixed , help!

My buddy put a 21” front wheel on his 2015 ultra and experienced a wobble. His mechanic couldn’t figure it out so he took it to a local dealer. Turned out it was the steering head bearings.

My 16 RGU lost a front wheel bearing at 14k.
