IML: Radial vs Bias Ply Alignment Specs

["Eric" <gearhead@xxxxxxxxxxxxxxxx>]

A brief net search gives some info on the bias ply vs radial ply tire issue. 
This site, http://importnut.net/tiretech.htm , a site specializing in import 
cars, shows that static negative camber of about 1 to 1 1/2 degrees greater 
is requred for radial tire equipped cars.

Of course, almost any automotive site search pulls up our website, and this 
radial discussion is pointed out here, 
http://www.imperialclub.com/Repair/Wheels/radials.htm
There is mention by a 'near expert' on the subject that toe it be adjusted 
to zero for radial tire equipped cars. Also of note, there is a mention that 
the standard Safety Rim wheels that Chrysler started using in the 30's-40's 
addresses the issue of radial tires demounting themselves from the wheel 
rim.

Does anyone else have some specifics on the subject?

Your mechanic is telling you the truth; you do need to adjust the toe-in =
for
radials.   I haven=92t heard about having to make a correction in the =
other
settings, but I=92d trust a skilled and experienced alignment tech - if =
he
says it is needed, then do it!=20

No one has mentioned this lately, so as you point out, we are overdue =
to
remind folks about this.
