Some people feel validated when other people make the same choices they do. Plus, it's a bitter pill to swallow if you spend several hundred (if not thousand) dollars and have to admit you made a poor choice.
I continue to regret every tire I've ever bought for my trucks that wasn't the BFG All-Terrain... including my most recent set. I bought the HD Terrain, for a few reasons, more aggressive tread pattern, 'designed/intended/marketed for HD truck applications', wasn't convinced about the less aggressive KO3 compared to the out of production KO2.
In hindsight, the HD Terrains are LOUD, and are so aggressive they actually vibrate the truck at low speeds. The tread wear, which was always amazing on the KO2's, is not nearly as good on the HD Terrain. I could overlook many of those negatives for a commiserate increase in off-road traction, but that isn't there either.
I'll also say that if I DIDN'T get the HD Terrain, I would be second guessing how much better they might have performed and end up wishing I had got them. Now I know.
One plus side, no leaks or punctures so far.
Regarding climate, it's warm here, snow maybe once or twice a year. The soil at my house is very loose and sandy and why I went with a more aggressive tread pattern.
