Chrysler: Low Profile Tires are DANGEROUS

Low Profile Tires are DANGEROUS
Ever hear of the 6.70-15 tire? Its aspect ratio was about 92.
In the 70's, small cars typically used ratios of 80.
In the 80's, ratios of 70 were common.
Today, absurd ratios as low as 40 are being fitted to cars. Avoid at
all costs these killer tires.
The lower the ratio, the wider the tire has to be to support the
weight. All things being equal, this means hydroplanning occurring at
lower speeds; possibly 10 mph lower. This is dangerous.
Hydroplanning with normal tires can be expected at speeds of 55 to 60
mph. Low profile tires may let loose at 45 mph. Since these "high
performance" and very expensive tires are sold to car enthusiasts who
likely will assume better, not worse, specs, this is dangerous. Such
lead footed drivers will quickly get themselves into hydroplanning
situations and wreck.

What you smoking?
There's lots of ways to get around this. Jack up the air pressure. make
stronger tires.
The only reason people ought to avoid lower profile tires is because
they were invented by the tire manufacturers to enable them to sell
more rims to replace all the bent ones caused by going over standard
sized chuckholes in the road. (they also look stupid, but that's another
thing)

Ummmm.... no. Tread design plays as large, if not larger role than tire
width in determining how easily a tire hydroplanes. Of course, if you
have to rationalize the "4 for $99" whitewalls you just bought at Pep
Boys, be my guest.

You're full of it and not even consistent in your own post. So is it 10
MPH or 45 MPH? Quite a difference.

"hydroplanning?"
Isn't that what they did before they built Hoover Dam?

Re: Low Profile Tires are DANGEROUS
FWIW-- my wife bought low profiles for her 96 Concorde about a year ago. With
the new rims, they looked sharp as hell, and handling in good conditions was
really good. BUT-- first snowfall ( and we had a LOT last year) they were
horrible. She wasn't into having two sets of wheels/tires for different
seasons, so she gave them to her son for his Cavalier.

Re: Low Profile Tires are DANGEROUS
Whether or not it's "student mechanic" posting this topic or someone
else, I tend to agree with him.
I had a virtual A/B comparision in terms of low aspect ratio tires.
I had a 1981 Plymouth TC3 ("sporty" extended hatchback Horizon) with
standard tires.
I also had a 1984 Dodge Rampage (mini-pickup based on the Horizon).
Same front wheel drive, approximate same weight, same engines (2.2
liter). The treads on the two sets of tires were similar, but the
Rampage had the low aspect ratio tires.
The Rampage was TERRIBLE in snow. The car spun out on me at slow
speeds many times. I finally totalled it when it slid down a snow
covered hill into a rock outcropping while doing less that 20 MPH.
The Plymouth TC3 was GREAT in snow....
Another similar experience happened about 14 years ago, when I pulled
a 4 wheel drive Jeep off of a snow drift with my 1937 Hudson
Terraplane (no kidding - yes, I'm an antique car collector). That car
had the old bias ply 6.00 x 16" tires - tall and skinny. Of course, it
did weigh something like 4,500 lbs.
Now my 1929 Model A doesn't do too well in snow but it has 4.50 x 21"
tires. That's carrying tall and skinny too far....sort of like balloon
bicycle tires.
My only theory is that "tall and skinny" tires put more load per sq.
inch on the road, biting better into snow.
That's just my opinion, I could be wrong....
