Tires or Stroker?

[ajpthng]

I've been doing alot of searching and I've been debating this for some time. I'm in need of new tires soon but I think if I play my cards right I can wait till I get back to the lower 48. At the same time I've started picking up parts to build a Stroker motor out of my 4.0, I'm almost at the point of gaskets and machine shop work I'm just missing 6 key parts.

I'm pretty sure I know the direction I'm going to go but I wanted to see what others had to say.
