if you just want some traction, buy some used rubber off the people selling on this site or 4wheeler.ca. $1500 seems high. Rubber should be under $1000 for four with cheapo wheels. spacers shouldn't be $500. even with labour in it seems high. spacers you should be able to do yourself with a spring compressor and wratchet set...
save up for next spring. winter is just around the corner.
my two cents.
