does that include rubber?

yea thats with tyres, jsut checked the tread on them then when i washed my car, 5.5mm on the front two an 5 on the back two not sure about the spare didnt wanna pull the sub an s**t out.


so the front have 68%
and the rears have 62%

only warn 2.5 and 3 mm off the four tyres


EDIT: by the way there firestone tz100 on the front an firestone wideoval on the back, both 235/45 R17
