how deep is the tread on new blizzaks
Remember, with winter tires only the first 50% of tread is really for use. After that, you have the equivalent of half-worn all-season tires. Blizzak special outer rubber differs from lower layer, too, as the maker informs. Winter tires with 11/32 new tread depth are effectively kaput at 6 or 5 / 32. You should not push regular tires below 4/32 in any case, see wet stopping distances at full, at 4 and at 2 /32 video comparisons on Tirerack.com.
