It's only fair to follow-up, right?

Had the Defender LTX M/S installed, stock size. They look slightly beefier than the OEM Yokohamas, though the measurements are unlikely to be much different.

The ride is great. Highway noise/hum is non-existent; so my main concern is taken care of. There's no way they can be worse than the Yokos off-road... but the tread certainly looks like it'll be better. No telling when I'll get to test off-road or snow conditions. I took them up a steep grassy hill on my property and pinned it; there was no hint of wheel spin, for what that's worth, lol.

Time will tell, hopefully they're better in all aspects than the Yokos. So far, no ragrets. I kept an OEM Yoko as the spare, since it only had a couple of thousand miles on it.
