That change in size shouldn't make any significant difference in
acceleration. Simply not enough diameter change to affect the ratio
much. Yes, the odometer will see the change, but not the "seat of the
pants" or "assometer."

Based on your other post, I think you were running the previous tires
GROSSLY over-inflated. 40 PSI on a light vehicle is ridiculous. Go with
whatever the placard on the vehicle says, ignore the "maximum pressure"
ratings on the tire.

There is a real, noticable difference. It's like a different car. Last
night I even accelerated up a hill in 5th gear. There are a couple hills I
was unable to drive up in 4th gear because of the curves, and had to shift
to 3rd to gather momentum to get up the hill. I can take it in 4th no
problem. Of course, because of the stiffer sidewall, I can get into the
corner a bit faster, too.

The difference is amazing. Also, I use this car for a job, and I have to
pay for fuel, so I want all the mileage I can get.

Okay, so you bought lousy tires, and you noticed the handling was poor
and the didn't last long.

So you noticed that even with the incorrect tires on the car, good quality
tires perform a whole lot better than $29 specials.

I think your differences have a lot more to do with the quality of the tires
than with the tire size. Tire size makes some difference, sure. But
lousy tires are just lousy.

Well lets see, you had tire failures due to the higher air pressure in
the new tires, but that didn't teach you to lower it. Maybe the head on
crash from the poor contact patch on these tires will do it.

The tire sidewall pressure is the MAXIMUM that tire can withstand NOT
the pressure you run them at. You get sidewall splits, increased tread
wear in the center, less resistance to tire damage, easier puncture
damage (and usually worse damage due to the higher pressure), Less
braking ability, poor cornering in the rain (if you can even turn with
the reduced tire contact).

Wait till you hit a wet spot and try to brake.. Slip Slidin' Away are
not just song lyrics.

Oh and if you believe that the extra air pressure saves you more gas
over the cost of replacing the tires, I have this neat tornado gizmo and
a couple magnets for you as well...

And another small item, The speedo and the odometer operate from the
SAME drive gear. If one is wrong they BOTH are wrong.

All four tires are firmly planted on the ground. As a matter of fact, they
*look* like they need *MORE* air!

I like this one!

I'll take it! Until one of the vanes breaks off and lodges in a valve...

Ya know, he's right.

So, let's see. If my speedo was right, and the ODO was underreporting the
mileage, then...

Bullsnot. The way a tire "looks" doesn't mean anything. Different tire
designs may bulge a little more or less, but that has nothing to do with
the actual contact patch, OR with the rolling resistance. You're not
necessarily saving fuel by overinflating your tires. Poor cornering
performance caused by overinflated tires scrubbing sideways costs fuel too.

That may as well be, but the Goodyear "Integrity" on my company car
are about the worst tires I have ever driven on. The Continental all-
seasons that came stock on my '02 GTI were pretty bad, but I think
these are actually worse. Either that, or the Impala's suspension
geometry just sucks.

That's a bad generalization.
Every manufacturer has both good and bad tires.

The Goodyear Integrity that came on my Toyota were crap.
The collective wisdom of tirerack.com rates them near the
bottom.

The Goodyear Fortera TripleTred that I replaced them with are
great.
tirerack rates them number one among highway all season.

Agreed.

I rather like them, but they don't deal as well with wet pavement as
the old Aquatreads do. They don't have problem on grooved pavement the
way the Aquatreads did, but I tried them after the Aquatreads were
discontinued and wasn't all that impressed with overall handling and
wet-weather performance. The Aquatreads were wonderful.

I suspect you must be joking. First of all 44 psi is the maximum tire
preassure not what you should use. Buying the cheapest tire you can
find?

Either this is some troll bs or you are to dumb to drive a car.
