Car Pulls? Industry-wide recall indicated.

Today's cars have a tendency not to hold alignment. They tend to pull to
the side no matter how good the alignment or how well maintained the tire
pressure, etc. I believe this is an inherent vice.

You will be told the tires need rotation. And, rotation may actually help,
that is because the tires will pull opposite and cancel out the inherent
vice, at least for a little while. After some wear, the tires will pull
again, often in the opposite direction of the original pull.

I believe the pull is not due to alignment or any other mechanical defect.
I believe the pull tendency is because of LOW PROFILE tires, now in vogue.
Anything lower than -75 will pull.
This means your -40's, -45's, 50's and even all the way up to -70's are
inherently defective.

How did we get into this fix? I firmly believe there has been a
how-low-can-we-go-profile-race. Just like the wider is better race of the
50's, horsepower race of the 60's and the lower roofline of the 80,s the
car companies get into these stupid trends. Now the trends of the past
were just nusciensces, but the low profile tire trend is outright mind
bending and just plain dangerous. I want, no, I demand a car car that goes
STRAIGHT 100 yards down the road with my hands off the wheel. I know it
can be done because I've driven cars that could do it.

Who's driving this low-rider tire trend? I think the companies are trying
to cater to that segment of the public who think low is cool and ignore the
mature public who will just go with the flow, having false confidence that
the eniggerneers at D-C know what the Hell they're doing. So, who thinks
these tires are cool? Its the greasers and colored who are free spending
with their money and actually retrofit $500 cars with $3000 22 inch wheels
and -25 tires. (-25 is coming, rest assured).

Its not grandpa who is lusting for these insane oversize chrome wheels and
rubber band tires. Its not NASCAR either. Professional drivers use tires
more like the kind you'll find on a '62 Impala. NASCAR demands performance
and performance is not what you'll get with those outrageous low rider,
****** wheels and tires. Its the darkies and greasers who want them and
all their white fellow travelers.

 

woa.. you're quite the racist.

You need to inform yourself more about tires.

A taller profile is not nearly as safe as a low profile performance tire.
Sidwall squirm results in poor handling, but the most important things your
tires do is help your brakes make your car STOP. A tall tire has so much
jounce effect and sidewall compliance that you can actually loose adhesion.

Remember the Ford Explorer??? That had tall tires didn't it?


NASCAR is ancient technology.. heck, they still use carburetors and
steering boxes, maybe they have drum brakes at all four corners too. They
also race on bias-ply tires with sticky rubber.. Today's tires have radial
construction, hence we can get low profile tires that will outperform just
about any tall tire ever made (F1 tires are tall because they SLOW the race
cars down.. on 13" wheels, and fairly tall profiles, ever see the sidewall
shift on a F1 car?!??! it's nuts). Lower profile tires also resist sidewall
heat buildup, where as taller tires have a tendency to build heat in the
sidewall due to compression.

Less rubber = better for the environment for the same overall OD.

Sex sells.. The 300C looks hot with 18" wheels, did you see the SRT-8 300??
19s, looks hot.

Look at REAL racing technology, like GT racing or ALMS (LeMans) those are
low profile tires.

The engineers at DCX know exactly what they are doing.

you may not like low profile tires, but don't be a racist.


Go buy yourself a 1982 Chrysler K-Car with 155/80/13s

BTW: You don't know much about profiles....

Nearly the Same OD - 155/80/13, 175/70/13, 185/60/13... The OD hasn't
changed, do you even know what the profile # means??

STUPID ****.

Troll.

 

Don't even bother. The troll has a six figure post count with similar
content. He's either got a robot, or - never mind - AND he's got no
life.....

A 1950s or 80-series height sidewall tire- true. But something like a
50-profile tire is about the optimum. These ridiculous "rubber band"
tires on 21" rims don't have ENOUGH compliance to attain good adhesion.
Its all about the proper compromises to ensure the best overall grip,
and too little sidewall height is as bad or worse than too much.

As a percentage of total tire diameter, so does an IRL or F1 car. Look
at them- they don't have a thin band of rubber around a huge metal rim.
Bringing up the Explorer is irrelevant to the discussion. What is the
height of the CG of an Explorer? What is the height of the roll center?
Do you really think it would affect the rollover rate if you put
20-series tires on 21 inch rims on an explorer without changing the CG
and roll center?

Wow, a statement dumber than those usually made by Nomen! For one thing,
NASCAR *TIRES* are as highly technically refined as the tires in F1,
CART, and IRL. There's no technology restriction there, regardless of
what type fuel system they use. And in the second place, you're talking
out of your ass when you even bring up drum brakes. You're obviously
clueless about all forms of racing, and about tire engineering.

 

I happen to race in CASC- (regulated by ASN/FIA) in Canada, equivalent to
SCCA Production series in the US.

Sorry if you missed the point. It's obviously my mistake if you didn't
understand what I was trying to put across.


I believe a NASCAR tire is based on bias-ply technology. The rubber on them
is certainly high tech, the tire construction is not. I have raced CASCAR
(a bit smaller of a series than NASCAR at Mosport (not the oval, road
course).

NASCAR doesn't use steering racks, that's what blows me away, and also, no
fuel injection. Heck, Audi is racing diesels in LeMans!! I'm not saying
what NASCAR does isn't wicked, they make BIG freakin' hp from a tiny
restrictor plate, however, it's still old technology. The rip was about
drum brakes... being a throw back to the fact they still use lug nuts on
the rims, as opposed to button lock or splined single nut systems, air
jacks, etc.. yeah yeah, stock car.. sure, and a Camry is RWD, hehe..

You also missed my point about F1 tires being tall. They are that tall
because ultimately they slow the cars down that way.

Heck, why do ALMS cars use rubber bands? Why do GT cars? Why do SP cars?
Cause they are faster in the turns, period.

Slip angle buddy.. it's all slip angle.

 

NASCAR tires use radial tire construction.



I have raced CASCAR

 

I currently race on cantelever bias ply tires, ancient technology as far as
construction goes, but super sticky compound that is modern ..

Cheers, and thanks for the update. Nascar stopped using Bias Ply a long
time ago it seems, I did some research.

 

Probably has more to do with well designed roads that have crown to aid
with drainage.

I was runnig 50' on my Omni GLH Turbo and it never pulled. Ran straight and I
got very even tire wear. Even with sticky low tread wear rating tires I would
get 45k miles out of set.

You obviously are clueless about tires. The profile has nothing to do with
a car pulling. Low profile tires are not inherently dangerous. If anything
they contribute to the safety of a car because generally speaking they brake
and turn better than other tires. They also tend to tolerat heat better than
other tires.

Nothing stopping you from buying higher profile tires. I know that lots
of people would be happy to take your low profile tires in exchange for higher
profile tires.

There we go. We finally find the reason you hate the 'tires'. You might be
able to get some help, but you have to admit you have a problem first.
