95 SC1 - what kind of tires can I use?

Discussion in 'General Motoring' started by Newsposter Guy, Sep 30, 2004.

  1. I have tires in the same size as stock (175/70-R14) but the front two
    are wearing down.

    I'm not terribly happy with these tires anyway, so I'm thinking of
    replacing the whole set. But it's difficult to find decent tires in
    that size.

    Tirerack is recommending 185/70-R14, which is more common. Can I use
    this tire size? Will I have any problems? Will I have to get new

    Thanks in advance.

    The 175/70R14 can be found if you look for them, but was somewhat unique to
    Saturn. We found some nice Cooper made 2000LTE's (70K miles) at Pep Boys
    for $41 each. Even with installation, lifetime balancing/alignment, road
    hazard package, and an alignment a set of 4 tires cost under $350.

    As to substituting a different size, this can be done and given that both
    are 14" and the increased width is only 10mm (under .4"), I would think they
    would likely fit fine on your existing wheels provided there is sufficient
    clearance. In the case you cited, replacing the 175's with 185's while
    retaining the 70 profile would result in about a 5.7% (if my calculations
    are correct) speedometer/odometer error (it would read lower than actual

    Use the calculator to see what happens to your speedometer reading when you
    change the size of your tires and wheels. The graphic shows your stock tire
    selection in an outline overlaid on your new tire selection.

    Better option is to use 185/65R14. This keeps about the same diameter but
    tires are slightly larger. This size was recommanded to me by other dealer.

    Nice site. Thanks for posting. This clearly shows that my earlier
    calculation was incorrect. (I forgot to add the 7" - 177.8mm wheel radius
    to the sidewall length so the speedometer error is less than half of what I
    had estimated previously.

    Other option is to check the circumferance of the stock tire by the
    manufacture website, most list this infomation. Then you can up your width
    to what ever you want (within reason) and know which tire is the same or
    very close to your circumference. Minimal if any speedo error this way.

    Anyone know how wide of rubber will fit on a 1999 SW2?
    I'd like to go to a 205, i think stock is a 195/65/15 i'm thinking of
    205/60/15 or 205/55//15 pending on manufacture.

    Thanks. I ran this tire size through the Miata calculator and you're
    right, it is very close. And a much better selection of tires too.
