Wheel Sizes & Offsets For Skylines

[Russman]

yeh front will be close to the UCA, bloody close, generally i say 235/45 with a +30 offset is the furthest in id go, 225/45 will protrude 5mm less in, and about 4mm lower, but u have 8mm more offset pulling the tyre in further. so it will definitely be close, and probably come down to the tyre model and individual car as to whether it actually scrubs or not, but nothing a spacer a few mm thick cant fix.

my bet is that it will clear, but no guarantees on that one.

do you know what the difference in diameter of a 235/45/17 tyre and a 235/40/18? I'm guessing only a few mm.

I had 17x9 +38 with 235/45/17's and they were fine on my 32.

Cheers for your help.

I'll find out in a couple of weeks when they arrive if I need to run a spacer or not, but I couldn't say no to the rims. Silver GT-C's on a grey 32.....mmmmmm tasty

Thanks for your input too Russman!

mm, yeh it comes down to each car and tyre design it seems, when i ran 235/45's with he +30 on mine, i could feel maybe a 3mm gap between the tyre and UCA.

Yeah i've had some bridgy 235's and they were way skinnier than a dunlop 235 haha. dunlop sat square and bridgy looked stretched!

[nisskid]

yeh when i used to drift on 2nd handies id go through so many tyres, and it was crazy to see the difference in them every time id put a new one on, all different brands had different shapes and clearances mounted up.

Great thread. Can someone tell me if 17x8.5 with +20 offset will go on a '93' R33? I'm looking at Otomoto rims.

Thanks.

[nisskid]

yes

Hey nisskid, going crazy trying to work out what to do with ordering new wheels, especially seeing as tho i cant trial fit...

Currently looking at a set that i can get in the following -

· 18 x 8 only comes in offset +35 and +45

· 18 x 9 comes in offset +20 and +36

· 18 x 10 comes in offset +15 and +35

would ideally like a mildly aggressive fit, but dont want to have to flare. dont mind a roll and removing the plastic guards tho.

looking at 18x9 +20 front and 18x10 +35 rears or just the 9"+20 all round on an R34 GTT lowered on nismo coilovers, no camber adjustment as yet

any advice?

thanks mate

thats a hard one, as 18x9 +20 would sit pretty nice and aggressive, but 18x10 +35 is a bit soft, and wont really suit the agressiveness of the front. u could go 18x9 +20 all round, but if u want to keep the staggered width, id be going the 18x10 +35 and correcting the camber to around -0.5, this will pull the top out, and give u more grip. from there id probably go extended wheel studs and some hubcentric slip on spacers to get the fitment perfect.

the 10" +15 can be made to fit without a flare, but ull need camber and stretch, and by the sounds of things its more aggressive than what ur after.

thanks heaps mate, pretty much what i was thinking.

its my daily after all so i'd prefer not to go too crazy, but i just remember not being entirely satisfied with my last wheels on my old 33 (cr kai 18x8.5 +32 / 18x9.5 +38). fit really well but could have looked a lot better, which is why im kinda shy of going the 18x9 +36 and 18x10 +35 in these wheels.

hey fellas how would these fit on an R33 gtst

18x9 +15 (front)

18x9.5 +15 (rear)

btw my rear guards have been rolled flat so shouldnt be too much issue there

also i was thinking tire wise

215/35/18's for front

235/35/18's for the rear

front might sit out slighty ive got 18x9 +30 on front with 25mm spacers and it sticks out about 20mm atm but putting wider front guards.. back should be fine

nisskid will be able to tell you better though!

[TaKz]

^^^^^^^^^^^^^^^

that set up should be fine although im not sure about those tyre sizes wouldnt that be not enough sidewall to stretch? well i guess it would jsut be harder to stretch

just a quickie

how bad would it be too occasionally run on the track

225/45R17 front

265/35R18 rear

cause i got spare pair of 18s with 265/35 and dont want to waste it

and i thought 225/45R17 would be good comprimise for grip/drift front tyre, i would go a 215 but i think the difference to 265 is too much

cheers

will be quite aggressive, id go a 225/40 on the rear. depends how much camber u have, as it will be tight, but depending on the camber u will get away with it.

running -2 degs on the rear and -0.5 on the front, so the fronts would be ok with that width and aggressive offset?

[NIS.26L]

Anyone know if i can fit 265/40/18 rubber on my r34gtr rims on a r34gtr? i got 245/40/18 maxxis victra Z4s on my wheels atm but it looks like i can go wider

cheers george

[nisskid]

i wouldnt recommend it, but it can be done.

[NIS.26L]

Any reason in particular? eg scrubbing? or tyre might come off the rim?

cheers nisskid

[nisskid]

tyre bulge, will mean the tyre can move around the rim a lot easier and make the steering indirect, too high profile, will put ur speedo out. any reason why u wanted to use it?
