Why would you even consider this? I just got a complete set of tires
for my 300 TDT from the Tirerack.com for $258. By running tires in an
unsafe manner you risk dying, among other things. Safe tires are a
necessary part of owning and driving an automobile, and a few hundred
dollars is not so much to pay.
I dozed off at the wheel and ran off the road in September. While my
car was relatively undamaged because I just landed in the soft sand of
a wash, the impact with my seat belt and steering wheel did around
$100,000 worth of damage to me, or at least that's what the hospital
and doctor bills total up to, and lots of pain and discomfort, not to
mention three months off work and a month in the hospital.
Get safe tires or park the car because you risk going off the road
just hitting a puddle if the tread is pumping water UNDER your tires.
And if you do go off the road, it is unlikely that you will be lucky
enough to just land in soft sand.
