Tire tread
Tread depth should not be allowed to
go below 1/8 in/3 mm, even though
European legislation, for example,
requires a mimimum tread depth of only
1/16 in/1.6 mm. Below 1/8 in/3 mm
tread depth, there is a great risk of
hydroplaning, even at relatively moder-
ate speeds and with only small amounts
of water on the road.

3/16 in/4 mm, tire performance under
winter driving conditions deteriorates
noticeably. Worn tires should therefore
be replaced for safety considerations.
