So my AHC crapped out and I've decided to bite the bullet and do a rear coil conversion and get new AT tires. I'd like to avoid wheel spacers if possible, even though I've seen plenty of people on here use them without issue. I know 285/70R17s won't fit without a spacer, but will 275/70R17s? That'd get me a tire that is almost the same size, but save me $200 in spidertrax spacers and remove one more potential point of failure (and make balancing the wheels much easier). Also, any advice on rear coil conversion would be awesome.
