For training purposes, it is recommended that I get a tire with bead to bead puncture protection in the form of a Kevlar belt or just a tire with protection under the tread?

Fwiw, I've never had a sidewall blowout. I've never even had any nicks or gashes to the sidewalls of my tires. Or at least I've never seen any evidence of anything on the roads here tearing up the sidewalls of my tire.

Which do you recommend? I'm leaning toward the belt protection only because I like supple rides and also I like easier to mount tires!

Specifically, I am thinking about getting either the Kenda Kountach (tread protection only) or the Kenda Kaliente Pro (belt to belt protection).
