cut tire replacement

Ok - so how much of a difference in remaining tread is acceptable when
replacing a tire? My wife had a tire cut about a month ago, and they had to
replace the tire (puncture was right on the edge of the tread where it
curves into the sidewall) - they only replaced one tire, and didn't say
anything about needing to replace the axle set - so how big a difference can
you get away with?

 

When all else fails or if you dont rely on eying it, there's always the
penny test.

Either way, dont play w/ your life or the ones you love, if youre still not
sure, best to have them replaced. Tires are cheap enough nowadays, lives are
not.

I probably should have been more specific - all of the tires have plenty of
tread on them, and are not in need of replacing - what happened was one of
the tires was damaged, and was replaced with a new one - so now, though all
4 tires have more than enough tread to perform properly, one has more tread
than the other three - I was curious how much of a difference was ok, and
determine if I need to replace the other tire in that axle set.

 

On a passenger car, where there is only 12/32 - 14/32 of tread to start
with, the difference between a new tire and a used tire with "enough" tread
is not an issue. Where there is a problem is with trucks with a dual wheel
situation with 2 wheels right next to each other and solidly bolted
together.

I think so long as the other tire has "legal" tread the tires are
considered "balanced".
