Wheel Sizes & Offsets For Skylines

I still didn't get my answer if i can fit a 18x9 up front.

9" wheels are a little too wide for a RWD 32. They can fit. People have put R33 GTR wheels on 32s for years and years. But they are a very tight squeeze. This has been known for about 30 years.

As I said - there is no difference between a 17 and an 18 in terms of what will fit. The rolling diameter needs to stay about the same as stock - not very much larger. If you increase that, you will start to have problems. If you increae rolling diamater at the same time as yo increase width, you will have problems earlier. as 9" wheels are pushing the boundaries already, you would need to be careful with tyre choice.

I would put 8.5s on the front of mine, but would expect problems with 9s.

yeh they are 235/45/17 up front and 255/40/17 in the rears.

I want to get 4 of this and see if they will fit before committing as they didn't see an 18x8 as an option but there is a 18x9.5 also.

I know a guy with 18x9 +22 on the front of a 32 gtst, needed quite a lot of guard work, tyre stretch (215) and camber.

Not sure what your current set up is, +35 won't be as much, but still a fair bit of guard work and camber.

9" +35 will rub on the suspension. R33 GTR wheels are +30.

ok so if i wanted to go 18's i would go for 8's  in front 30+ or 32+ off set at front and the back 9 would be ok? what offset should i aim for.. then can i do some  hunting for wheel rim choices.. 

 

If i get this - will this fit all around:

Size: 18 x 8.5 +37 - n what tyres size tyre should i get for front n back?

8.5 +37 = should fit rear, but I think it'll hit on front.

What you want is low 30s/high 20's front, mid 30's rear. That 17" screenshot you posted looks good, I'd run it on my R32 (but that's long dead now).

For tyre sizes, my rule of thumb is: 8': 235, 9": 255. But that's just my opinion.

Nismo sizes: 18x8.5+35/18x9.5+38 is a good starting point.

Wanted to add some of my R33 GTST 

R34 GTR wheels, 18x9 ET30 with 255/35/R18 PS4S'

 

BBS RE-V7 029 18x9.5 ET22 with 255/35/R18 PS4S'

Needs a bit of camber

Dang, those BBS are so nice!

Will this fit? but they are staggered set -

RAYS 57DR SEMI GLOSS BLACK 18x8.5 +37 | 18x9.5 +38 5-114.3 STAGGERED SET

 

or If no go could just get a set 4's wheels of 18x8.5 +37 5-114.3 - would i run 8.5's 235s up front n 245's at the back if I do?

 

Thanks.

If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

If only it were that easy!

I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers.
It can be hard sometimes

Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering.. 

Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.
