A 27.5" rim with a 2.8" plus tire creates an overall wheel diameter very close to a 29" wheel with a standard tire—approximately 29" in total. This is why the 27.5+ format was initially called '27.5+ = 29' by some brands. However, the ride feel is different: the 27.5+ wheel has more air volume, a wider contact patch, and different flex characteristics. The rollover ability is similar, but the traction, cushioning, and handling feel are distinctly plus-like rather than 29er-like.
