I looked through the archives for some way to keep my left front tire from wobbling at accelerated speeds on pavement. About all i found was to deflate the tires. My tires are just recently changed to solid rubber so that was not much of a help. I tried tightening the seal top bolt and only could gain one click on that 1-1/16 socket connection. Turns out the tightening was quite effective. Can travel at much higher speeds without wobble.
