Well, that was pretty much how I took the '25%' comment - all sizes of the Ecsta 4X look to have 10.5/32" new tread depth, so if you discount that first 0.5/32" (why do manufacturers bother trying to define tread depth down to 0.006" anyway?) as your 'scuff' during break-in, the usable tread on the tire amounts to 8/32".
