You touch on one of my biggest complaints with the Hightower... More with SC's marketing than the bike. The Hightower is not a plus bike, even though they originally sold and marketed it that way. It will only accept a 2.8" tire in the rear. That's barely plus... The only true plus capable bike in SC's lineup is the Chameleon. Its tire clearance starts where the Hightower stops...
If you were to try a real plus tire, which you can't on the Hightower, your conclusions would change. The 2.8s look like road tires next to a 3.0 and the overall height difference is maybe 1/4". With a really knobby plusser, it's not even that.
I'd be willing to bet that the proliferation of true plus capable bikes (The Smash for one...) was partly behind the decision to stop offering the Hightower as a plus bike. They have removed the word "plus" from all of the marketing on the new Hightower, and state specifically that it is only compatible with 27.5 x 2.8, without mentioning the word "plus".
Nah, they stopped selling the Plus Wheel option because people were not buying them.
