So I thought about getting a decent microphone, as my 99p shop microphone held in place by a tie and a shirt was not giving me the best quality, so therefore I purchased a Blue snowball microphone, apparently it is the best for the money so I went with a second hand one, all is good until I realise how much FFB noise it picks up, haven't really done a full test yet but it seems to be quite bad at the moment (and this is in Cardoid mode not Omni mode)
Is the mic connected to the same thing that the wheel is connected to? If so i'd try and place it on something separate. But if that isn't the problem then IDK what to do. I haven't gotten heavy into making vids yet.
If your microphone is on your desk next to your wheel my plan will work (I hope). If it's hanging over it IDK. They sell foam sound barrier walls for mics that are usually put behind them to prevent any noise bounced off of walls from coming back into them. You could try putting one of those between your mic and your wheel. Best of luck
