17's or 18's?

[chris97pittman]

Ok I have motegi rims, and I'm wondering they looked big to me for 17's because that's what the tires say...so I went and measured and they're 18's on a tape measure and 17's according to the tire, what the hell does that mean?

correct me if im wrong, but rims are measured by circumference, not by diameter.
and, the tires are always right. if its a xxx/xx/17 (ex. 205/40/17) tire, then its a 17" rim.

when i had stock rims on my talon, you could measure across the diamter and they would be 17", but the actual rim is about 1" smaler then the exterior diameter. And the tire is always right too. So if you measure 18", the tire says 17", it is a 17" rim.

yeah...dont really on the size with the tire...if the tire says 17 it is a 17...if you mesure it with the tire included then youre factoring in the aspect ratio of the tire also and it will throw your mesurement off....its all about working in the Sams club tire and battery center..

you guys are also measuring the lip, notice that tires recess within the rim, and within the lip.

but come on...

just because you measure 18" then wTF or how T.f did they get 17" tires on there.



"common sense. because it doesnt hurt that much."

If you take the tire off of the rim and measure from the lip down to the inner surface of the rime it should be really close to one inch. Therefore making your rims 17's. Like a couple people have said. If the tire said 17 inch then your rim has to be 17 there is no way to put an 17 inch tire on an 18 inch rim.

Ok, with said even being 17's I have people that have 17's and theirs look huge, is it becuase lower profile tires?

....

a 17 is a 17..

it may "look" bigger.. but its not

i dont think they come out of the factory going.. yep that looks about 17 inches to me.. yep ship it.

maybe it has a bigger lip? maybe the design effects the way you see it? tire profile "might" make it look different.. dunno how.. but if im looking at the rim.. im not looking at the tire.
