Re: [Chrysler300] Danger of wheel failure unless the rims are replaced by str...

Hi Gil,

Regarding your awaiting a real tire expert¹s statement that the pressure on
the bead area of bias ply wheels is greater when they have radial tires
mounted on them, what about ³Old Tire Man¹s² quote:

Nickname: Old tire man
Review: You're neglecting a very important design fact when comparing radial
and bias tires and rims: How the load is transferred through the tire to the
rim. Radials transfer the load (vehicle + payload) to the bead of the rim
and bias transfers the load upwards through the center of the rim, ie, bias
rims are thinner at the bead area than radial rims. I was there when we made
the transition to radials in the 1970s and I can't tell you how many bias
rims I personally have seen 'peeled' at the bead when a radial tire was
(wrongly) mounted. I won't mount a radial on a bias designed rim, but then I
have many years of personal (in a professional setting) experience to rely
on. Safety first.

Regarding the ³K² wheel covers coming off, there are 2 recesses in the ³K²
wheel covers that engage the 2 bumps in period Mopar wheels. They are on
either side of the valve stem.

For those that insist on frequent cornering to the limit (not that there is
anything wrong with that!) I would agree stronger rims would probably be a
good idea.  As to the assertion about the radial side wall flexing
("twisting") being worse for the rim bead area than bias---I'll await a real
tire expert's statement before I buy that.

However, I think that was a function of the "K" wheelcover's one piece
construction more than the wheel.
So there you are---my opinion on the subject and I'm stuck with it!
