I know that auto and tire manufactures all agree that cross rotation
of radial tires (except uni-directional tires) is the desired rotation
method.
What I'd like to know is why radial tires, when they were first made
popular, were restricted to same side rotation. I mean physically,
what was it that forced this deviation from the standard?
Second, what have they done to the design of radial tires that now
allows cross rotation?
Third, have these changes only made cross rotation possible, but not
necessarily good for the tires? That is, aside from uneven wear,
which is rotation method is actually better for the tire?
I'm pulling these numbers out of thin air, but they illustrate my
question.
Original radial tires:
Cross rotation has 10 failures in 1,000,000 miles
Same side has 5 failures in 1,000,000 miles
Newer radial tires:
Cross rotation has 5 failures in 1,000,000 miles
Same side has 2 failures in 1,000,000 miles
Does anybody know the actual failure rate?

Re: Rotating tires -- Procomp directional treads
Matt, one of the major tire manufacturers... it had to have been BFG,
Goodyear, or similar actually answered that question years ago. They
explained that the first radial tires were manufacturerd on the same
equipment used to make bias-belted tires which causes problems. What
problems, I don't know.... other than you couldn't cross-rotate them.
Then they came out with different manufacturing equipment that was
specifically designed for radial tires that solved the issues with the
first generation tires. I read it with my own two eyes, it wasn't my
friend's cousin's brother-in-law that related that to me. :)

Re: Rotating tires -- Procomp directional treads
It is my understanding the differences from the first gen radials was in
their construction and how the radial belts were made into the tire
compaired to todays construction new gen radials. I think it all had to do
with the belts and which direction they were wound but do not quite me I am
going from memory.

Re: Rotating tires -- Procomp directional treads
It is my understanding the differences from the first gen radials was in
their construction and how the radial belts were made into the tire
compaired to todays construction new gen radials. I think it all had to do
with the belts and which direction they were wound but do not quite me I am
going from memory.
