    mga tol tama ba formula ko to compute for the overall wheel diameter?

    Tire width * Aspect ratio = Tire sidewall height
    Tire sidewall height * 2 + Wheel diameter = Overall wheel diameter

    i was wondering kase ano sukat ng mags at goma ang equal sa stock ng altis which is 195/60 R15.

    Just google for a 'tire calculator' to solve your worries. :D

    The rough computation is section width X aspect ratio (in percent). So 195 X .60.

    The answer you will get is sidewall height.

    Sidewall height X 2 + rim diameter will give you overall diameter.

    But nothing beats actually taking a tape measure and measuring the actual tire installed on the actual rim.

    thanks, i found this site http://www.1010tires.com/TireSizeCalculator.asp.
    tires measuring 245/45 R16 would be slightly bigger sa stock ng altis. may ganto ba sukat dito sa pinas?

    Very hard to find tires in that size... and they're usually sports tires, which cost quite a bit.

    I'm also pretty sure 245's will rub on the fender liners when you're turning, unless you have the proper rim offset. You'll also probably need to make sure you have a 7" or 7.5" wide rim for that. 245s won't fit well on your regular 6" wide rim.

    Ang pagbalik ng comeback...
