its down to the balance for defo,
I had to do it every day for 5 years,
Typical small problem that could of been avoided, if they are alloy wheels there should be no marks at all
As the weights would of been stuck on the inside, but some people put hammer on ones on the out side lip,
Place's usually charge between 5 an 8 euro a wheel to get it done.
Get the 2 front wheels done an the problem should be near enough gone, you can NEVER totally get rid of the problem, but close enough that you shouldn't notice,
And if cars not pulling when letting go of the wheel it doesn't mean you dont need 4 wheel alignment, so best off getting it checked with new wheels just to be safe.
