which way does it wobble, left to right or up and down like the wheel is oval.
tyre problems i have had lately. tubeless tyres are tighter on the rims and dont seat properly. cure= use hand soap on the rims take out the valve and inflate with compressed air not a foot pump. the idea is that the tyre needs to expand to the edges of the rim quickly and at high presure or the tyre will just find a comfy spot and just sit there. to shift it from that spot is near impossible. the idea of not fitting the valve is that the tyre will inflate fast, you will then need to deflate and re inflate once the tyre is seated.
the feeling of the tyre being oval i have found to be one of two things. the tyre will have a heavy and a light spot. most tyre firms mark the tyre with a yellow dot which i think is the light side. the light side goes with the valve. if you get it wrong then the heavy side of the tube and of the tyre is on the same side so the wheel is off balance.
the other one i have had is from using slime in my tubes. in a hot day the slime becomes more liquid and runs to the bottom of the wheel and re jels into a lump. i cut a tube open to see this was the case. i think i had put too much in as well.
some old shocks loose damping unless they are fully compressed which means at low speeds you can get rebound bouncing, same as if you run a spring thats too hard for the damping to cope with.
im sure i have not provided a cure but this is this years wheel paranoia for me.
