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?

    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.

    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....

    What tire pressure do you run in your Hudson and Model A?
