Any "tips" on how to stencil drag tires?

[BACKN 68]

Have a set of M&amp;H Racemaster Muscle Car Drag Tires on the way for my street cruiser, and would like to &quot;letter em up&quot; for that race car look. Was thinking about having them mounted first, and then tape-off the letters and spray or maybe spray and then use lacquer thinner for cleanup of overspray? Which method would be more correct?

And would you spray just the large <span style="font-weight: bold"> </span> M&amp;H <span style="font-weight: bold"> </span> or the smaller racemaster letters as well?
