If your 2004 Impala has 16" wheels on it...these are a perfect fit for your Impala suspension, and tire clearance and performance...you can read the sidewall tire size on your car to confirm the 16" wheel size...the tire will read just like your replacement tire 225/65/16...many came with these...I will check factory specs if you will respond...Thanks.
You can replace, but not mix. All the tires on the car needs to be the same size for traction control and ABS system. Having two different size tires on the car will cause problems. Just keep them all at the same size P215/60R15 or P205/65R15 only.
Something as simple as a different tire size can cause the abs to go
nuts. I even had it where the two tires were the same size. But a
different brand name. Each manufacture has their own tire sizing so not
all tires a equal in size. Even though it says on the side of the tire
that they are the same size.
Sometimes the cooper inside the insulation of the wires going to the sensors corrodes.
Especially on the front units. It reads more ohms than normal but not
open and is very intermittent. However moving the wires my make it work
for a while. That's why replacing bearings seems to fix the problem but
it comes back after a while.
You can test the speed sensors yourself...
Front sensor specs:
956 to 1240 ohms in 41 to 110 degree weather
at least 100mV AC (NOT DC!) volts when hub is spun by hand
Rear sensor specs:
950 to 1300 ohms in 41 to 110 degree weather
At least 100mV AC (NOT DC!) volts when hub is spun by hand
Here
is some information from service bulletins that could be related to the
problem. The traction control, antilock brakes, and tire inflation
monitor all use wheel speed sensor input.
This first bulletin seems like it could be the problem because engine movement is involved:
GM Corporate Bulletin 00-06-04-049B
This Bulletin covers a problem that can cause multiple failures, one of
which is an Antilock brake problem, and covers 2000-2003 Impala and
Monte Carlo built prior to 2/03.
Check to make sure the wiring harness adjacent to the AC
accumulator/dryer is not rubbing against the ac accumulator chaffing
through the insulation of the wires in the harness.
