[VAC] Re: what brand of tire is good?

["Dr. Gerald N. Johnson, electrical engineer" <geraldj@xxxxxxxx>]

Radial sidewalls are more flexible so absorb bumps better but also allow
more side sway than bias ply tires. This is true of tractor radials also
making it more difficult to cultivate with precision. That's why bias
ply tires make the trailer be more stable, while radial tires let it
sway side to side more, at the same time riding smoother and rolling
with far less friction.
