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.
Tread depth. The legal minimum tread depth of the main grooves of car and similar tyres in the United Kingdom and the European Community is 1.6mm. This applies across the central three quarters of the breadth of tread and round the entire outer circumference of the tyre.ost car type tyres have tread wear indicators, usually at least six small ribs across the bottom of the main tread grooves, and when the tread surface becomes level with these ribs the tyre is at the legal limit and must be replaced.
