Charlie-
That's OK, I'll bet if I totaled up what I've got in this tractor I'm over the $1000 mark anyways, at least I'm in the home stretch. I'm not about to milk building this thing for another 3 years!
Besides, they'll look better on the front than a set of chevron tires, with a wide front stance, widened fenders, and 10.50 rear tires, it'll look too much like a pulling tractor. Plus wide front tires make for just another little spot to add decent fluid weight.
