I think this is the best we can do here.
If I were in your position I would certainly take it to a mechanic and have them poke around.
On the benign end, the hard breaking could have rolled the tire bead and allowed air to slowly escape... the smell could be an unrelated plastic bag that found its way onto your exhaust.
On the serious end, the hard breaking (or striking an object) could have caused damage do your suspension or drivetrain components. The burning may be a CV joint ready to give and allow the wheel to leave the vehicle in a catastrophic manner... perhaps suspension components are bent and the smell is the tire or wheel rubbing against vehicle components.
It really needs to be inspected in person by someone who knows what they are looking at/for.
