I thought you got other bikes front wheel bearings checked and it wasnt that, so get these checked before you invest in tools or bugger about knocking them out only to find it isnt that.
You obviously lack the required as dont even have a decent stand. I ordered a becker stand and bought a new scissor jack for the sump same time as bought the bike, since replaced for a scissor stand.
You jack front wheel, spin wheel, feel for side play, if they rumble they are f*cked, if there is play they are the same, if there is none of that then it aint your wheel bearings.
As for tyres they are random, on a specific stretch of potentially smooth road I have bevel box whine, no where else in my county only a 2000 yard stretch of road
Check front torque/reaction arm mount for play, it's two fat o-ring type bushes to replace or swap for a silent bloc.
If it has a silent bloc check for cracks in the rubber, check if frame hole that mounts it is ovaled out.
Symptoms are squeaks, groans, judder sounds, usually in low gears, low revs, sounds can eminate from front to middle of bike.
Sound really perplexed me, checked everything obvious during first week of ownership, even removed fuel tank which started me off on other quests, breathers/mounts/battery tray blah!
Easy to access just be careful when dropping side plate down as brake light wire is connected.
Side plate only holds foot peg and brake lever assembly and looks pretty compared the the stelvio's naked frame look
Cant imagine any other sounds eminating from your bike more hideous, except maybe mounting highway pegs with an over long bolt that twangs against the flywheel
Original mount [You must be registered and logged in to see this image.]
Silent Bloc upgrade/Not, has potential to silence o-ring issues but can wear mounting holes in frame mount oval in my opinion.[You must be registered and logged in to see this image.]
It's a service item and can affect bikes as low 13k miles, once swapped for silent bloc can fail every 10 or 20k
Front is towards bike engine, back is towards bevel box.
