sporty white tires


hi every1, bought a sporty a week ago and it has large tires on it wich the tires on the front have the letters picked out in white which i like to see but the ones on the back are slightly different and do not have the lettering picked out in white, is it possible to pick these letters out manually by hand by some kind of marker. forgive me if this turns out 2 be a daft question,


Marker pen

I saw a white marker pen in Halfords for marking the lettering on motorcycle tyres. Cost about £6.
