there was a company that used to make dry transfers, i am not sure if they still do.
but they had white & yellow 'Goodyear' in 1/24 or 1/25.
easiest way to apply them would be to mount the tires backward and apply them
to the smooth side.
Slixx makes decals, but you end up w/ silvering issues.
maybe if you got a soft artists pencil in yellow or white,
you could rub it (sideways) over the raised letters instead of
trying to 'write' on the letters tops,
