RE: Fw: Radials or bias? slicks

[Steven Charette <stevec@xxxxxxxxxxxxxxxxxxxx>]

It was explained to me that since radials generally corner better, it would
be easy to get into trouble when you crank the steering wheel at speed and
the back bias tires wouldn't grip (as they would if they were radials).

As Rich mentioned, it shouldn't be an issue going in a straight line, as
long as radical course corrections aren't needed - and at that point, you
may just be screwed anyway (another car in your lane, etc.)

We see some wicked fast cars at Mid Michigan (8-9 seconds) running on 10.5"
radial street/drag tires - I'm sure their suspensions are tuned for the
tires, but they seem to "hook and book".

If I remember correctly (man, this is going back a few years) radial tires
don't tend to "pile up" tread in front of the contact patch with the road
(the way bias tires do).  Take a look at launch photos on drag cars -
there's practically a tire chock of material in front of the slick that
needs to be pulled along under the car.  I'm guessing that's where radial
slicks shine... no energy is wasted rolling that extra material along.
Dvorak calls out radial slicks as one of those last ditch items you pull out
when you need a tenth or so... for those of us with a little less
horsepressure, they are probably great all the time.  See item six in the
link below.

I was always told not to mix them because the tires track differently. 
Going moderate speeds could become dangerous.
