All usable wheels need balancing. It is possible to diy them with gear to allow the wheel to rotate freely, 10g weights and multiples are needed.
As for grot, post #51 shows an alloy wheel with a centre that needs cleaning.......a rotating wire brush on a drill is perfect.
To remove the tyre you need the rim to be secured, a centre pillar that goes through the wheel centre and a long smooth bar that you pull on to ease the tyre over the rim. Crowbars will tear the tyre and shred the rim.
I should say, I'd never attempt this with a car wheel, I limit my experience with lawn tractors - and they are bad enough.
