Tire/Wheel questions.

I got a set of 16x7 wheels dirt cheap with the intention of reselling them, but the bolt pattern is the same as the Swift’s and I think they’d look pretty good on it. The problem is, I’ve heard 16"s are too big for the Swift. How do I tell without mounting tires?

The stock tire is 175/60-14…so what should I go with on the 16x7 wheel?

205/40-16? 215/35-16?

And if they are too big for the car, what are my options? Rolling the fenders?

here’s one of the wheels…

i know American Racing isn’t exactly BBS or Enkei, but I got these things for $60 (for the set).

i am guessing your problem will be with the width of the tires so you car run a 205 tire on 16x7. once you do that you can roll your fenders, run spacers, or bang out the inside of the wheel well.

thanks. i’m thinking that when the car is starting to come together I’ll pick up some Yokohama Avid H4s and go from there… I’m sure that one way or another I’ll be able to fit those wheels.

ehh its not as easy as you think… but good luck

They don’t look bad.

you really think its a good idea to be putting on those rims on that car?

i’d like to find something lighter, but otherwise yeah.

16’s are too big for the swift. they will def slow you down. i say nothing bigger than 15’s or better yet some deep dish 13x8 panasports, or rota oldschools on 195/45/13s.

find someone to buy my 16"s!!

I’d actually prefer a 15" wheel (less of a pain in the ass), but I’d have to sell these 16s first.

maybe my mustang could fit those :dunno:

i know nothing about wheels

they’ll fit a 4-bolt Mustang, but I’m not sure what the offset (backspacing) is.

Quick lesson in metric tire #s

Let’s use the stock tire size for an example: 175/60-14

The 175 represents the section width of the tire in millimeters. This is not the tread width, but the width at the widest part of the tire (so somewhere at the sidewall) as installed on rims of the manufacturer’s choice (this is why some xxx tires are wider/narrower than other xxx tires, the same tire will have a different section width on 6" rims than 7" etc).

The 60 is the aspect ratio, which is used to determine sidewall height. It is the percentage of the sidewall height as compared to the section width. So a xxx/100-xx would have exactly as tall of a sidewall as the tire is wide. So your tire has sidewalls 60% as tall as the tire is wide (175 * .6 = 105).

Of course, the final number (usually preceded by one or two letters, if there are two the first is the speed rating and the second, or only, should be R for radial) is the rims size, so 14" in your case.

To find the (approximate) overall height you will do 2 * 105 (2 since you have to count the height of the sidewall above and bellow the rim), convert that to inches and add to 14. Then do the same for your prospective tire size and you can see if you can come up w/ a 16" tire w/ a realistic aspect ratio (aka not rubber bands) that will fit your car. So you want to find X such that…

[2 * (175 * .6) + (14 converted to mm)] = [2 * (205 * .X) + (16 converted to mm)]

Note: 1 inches = 25.4 millimeter so the equation becomes…
[2 * (175 * .6) + (355.6)] = [2 * (205 * .X) + (406.4)]
----> 565.6 = 410 * .X + 406.4
----> 159.2/406.4 = .X
----> X ~= 40

So you would want a 205/40-16 for the same overall height. Of course, dealing with the width is a whole other issue.

ok i’ll just stick to my wheels and call it a day
thanks TJ for that overwhelming feeling :scared:

excellent post, TJ. thanks.

i found X to equal .389…

So a 205/40-16 tire would be best if the wheels + tires will fit in the wheel wells?

Yup, we found the same # so it looks like a 40 series 205 is for you. But the offset of the wheels and overall width will determine whether or not they fit.

Are wheel spacers okay to use?

Depends on the size and style. You don’t want to go very thick at all w/ the ones that just slide over the wheel studs (they reduce how far the lugs thread onto the studs etc.). There’s the type that actually bolt to the studs themselves and then have their own set of studs for going really thick, and if installed properly w/ good hardware are every bit as safe as not using spacers (they’re pretty popular w/ the 3rd Gen. Fbody crowd to run 4th Gen. wheels) but the spacers are pretty pricey and at that point (in your case) you might as well buy wheels that fit.

TJ can solve my equation any day… :naughty:

What the hypotenuse of my cawk?

Your cawk is triangular!?! :stupid: :wtf:
