    I'd like to ask your experts' suggestion on this.......

    I just got my new vios 1.3e, and I'm planning to change my rims to a wider and sporty one, I'm just wondering if there are some computations and calculations to arrive a safer or practical rim & tire size considering the given specs of the car, kasi for example, di kaya ng makina or mag over rev or overheat, o di naman kaya mgkaroon ng effect sa ratio ng engine....

    Baka siguro kung mg wear out na yung tire saka nako magpapalit...

    I believe the stock rims are alloy, 13", im not realy sure... so...can you help me....

    thanks.

    you shouldn't be too worried about the weight since most aftermarket wheels are alloy too.

    what you should be worried about is the size. how big do you want your wheels to be?

    you should consider diameter, width & offset, and profile. and make sure they fit well on your ride

    Wheel and tire size calculators abound on the Internet now. Here's one of them:

    Width and offset are quite critical in choosing wheels. On Jazzes and Cities, for instance, offsets that are too low and/or wheels that are too wide can cause rubbing with bodywork parts like fenders, especially with rear passengers or load. I'd assume it's the same with Vioses.

    A typical wheel code looks like this: 16x7.0J ET 45

    16 = wheel diameter in inches
    7.0 = wheel width in inches
    J = wheel profile type
    ET 45 (or +45) = wheel offset

    The greater the offset, the more tucked-in your wheel is toward the middle of the car. Conversely, less offset means a greater tendency for it to stick out of your fender...and give you rubbing problems.

    Try checking your stock rims to see what offset they are, and find a matching offset for the wheels you're looking for to ensure they don't foul up your fenders or mud guards or whatnot. If in doubt, go for greater offset than stock.

    This is the classic tire and wheel size calculator from Miata.net. This has been around since...well, forever.

    Another thing: Try test-fitting the wheels first. They might snag on some parts as they rotate, such as the front brake calipers...and that's not a good thing.
