Your vehicle has a clutched engine cooling fan. 
When the clutch is engaged, the fan spins faster to
provide more air to cool the engine. In most everyday
driving conditions, the fan is spinning slower and the
clutch is not fully engaged. This improves fuel economy
and reduces fan noise. Under heavy vehicle loading,
trailer towing and/or high outside temperatures, the 
fan speed increases as the clutch more fully engages. 
So you may hear an increase in fan noise. This is 
normal and should not be mistaken as the transmission
slipping or making extra shifts. It is merely the cooling
system functioning properly. The fan will slow down
when additional cooling is not required and the 
clutch disengages.

You may also hear this fan noise when you start 
the engine. It will go away as the fan clutch 
partially disengages.

It’s unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a few
tips about what to expect and what to do:

If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off 
the accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake 
to a stop well out of the traffic lane.

A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in 
a skid. In any rear blowout, remove your foot from 
the accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may 
be very bumpy and noisy, but you can still steer. 
Gently brake to a stop
