Wheels - 17in vs 18in

[slip]

is the 350z your dads?

if you are keeping the same rolling diameter, there will be more than 5mm difference in sidewall height.

just look at the tyre prices.

17x8 > 18x7.5 for grip.

thats right, 1 inch difference = 1/2 ince sidewall difference, 2.54/2 = 1.27 cm

im personally going for 17x9 deepdish 3 piece mags with 255 at the bak and 235 on d front, i hope the ride will still b nice

Ever noticed how much room there is between the upper suspension arm and a 17 inch wheel on a 33gtst, not a hell of a lot, i know 18s fit but i would love to know the clearence between said suspension arm and tire of 18 inch wheel.

Im talking about the front by the way to.

17 for GO, 18 for SHOW.

Soooo well said...

does any one here wanna buy a new 17inch racing wheels? if u want please let me know~~~ [email protected]

if reasonably lowered (not to the shit either) + 18" rims + full lock turn.. you'll get rubbing.. which is not good for anything..

if you mainly use your car for nice cruising with the odd fang, you probably won't notice it and 18's are fine. If you push your car to its limits and find yourself locking the steering up on a regular basis, you're probably going to want 17's IMHO.

snake, youre meant to keep the same or similar rolling diameter, which means that if you have an 18" wheel, the sidewall of the tyre is shorter, giving the same or similar height as that of the 17" wheel/tyre package.

nemz - sounds good mate.

18in equipped and grinning!

My advice...(for what it's worth) go for the 18's!

Ride is not much stiffer (remember I swapped from 17 to 18 on the same car).

What is all the fuss about?... sounds like short man's syndrome to me:)

18's fit easy, ride is still great, car handles much better, tires are getting much cheaper as time goes on as they get more popular, the whole package was only a few hundred buck more than 17in option, backend feels 100% better, no rubbing, and to put a cherry on top they look way, WAY, better (265x35)...etc, etc.

Wheel choice is very limited though for 18x8 18x9 set up.

I appreciate all the advice and comments.

Yes thats the theory, i havent had a good look at an 18 on a skyline with decent tread, but i have noticed on some other cars that go for bigger rims they still get a slightly larger rolling diameter, only slight

:devfu: :boobies2: :ufo: :bat: go 18in it,s much better than 17in. red and black LM are the best mate trust me

just use something like this calculator to make sure you're within 5% of the original diameter:

As for 17 v 18, I have both for my car and as said above, the 17 tyres are heaps cheaper.

One other advantage not mentioned yet is that generally the 17s are a fair bit lighter than 18s, unsprung weight degrades handling, not improves it....
