nope. A front tire failure normally happens when the tire is
damaged and the tire is under extreme loading, such as under
braking or turning at speed. Even when going straight, a tire
explosion can throw the vehicle into loss of control.
As an active mountain biker, my tire is always under abuse from
sharp rocks, roots, pebbles etc from the offroad terrain. Some of
the bikers in oversea countries have their tire cut by sharp rocks.
As they descend a slope and turn, the forces resulted in the tire
failure, which caused the rider to lose control and crashed
horribly. It resulted in him breaking his arm..
Yeah. The tire is normally dragged across, which subjects the
tire to massive lateral forces. Therefore sidewall strength and
condition must be good, otherwise the tire can fail. Likewise in
this case, the tire's sidewall had been damaged prior to entry to
the int. When the bus made a sharp turn , the tire's sidewall is
subjected to the massive lateral force. However the damaged it
incurred previously meant that the sidewall couldnt withstand the
lateral forces and the tire pressure within, which lead to a
blowout.
negotiating a turn makes a front blowout even worse. at certain
speeds front blowouts can still be salvaged.
still though, referring to your reply to ben, yes because of
this scrubbing its actually the sidewall which is more in contact
with the ground now. thus the sidewalls must be properly
maintained.
i'm just wondering if sbst checks tire conditions regularly or
not, or do the drivers check. a few weeks ago, while waiting for a
bus in ang mo kio, i spotted a svc 76 B9 with its right outermost
rear tire sporting a huge bulge.
a certain section of the sidewall was bulging really badly. does
this signify the possibility of a blowout? this isn't the first
time i've witnessed such things - once a merc on svc. 86 had a
portion of its rear tire sidewall bulging so badly it could be seen
sticking out of the wheel arch when looking across the side of the
bus.
