Wheel Sizes & Offsets For Skylines

[Jazzadub]

Right - 45 is huge offset so there shouldn't be much of an issue on the fender.

I would be more concerned about inside clearance.

[ridebmxyo]

Yeah that's what I thought.. I was hoping somebody had similair cause all my measurements tell me it will fit but I'm not 100% certain and I'm a bit skeptical... If I go plus 30 I'll have to run camber or stretch I'm thinking... I guess if I go+41 I can always get a spacer

[sleptema]

fairly new to all this.. I have a r34 gtt and im looking at running 18x10+41 rear and 18x9+25 front I want to run minimum amount of stretch and camber, Ive already rolled the guards all round and im running nismo s tune suspension

Short answer on the rears? No.

For a rule of thumb, 18x9.5+25 is pretty much FLUSH with the guards, front and rear at 0 camber. Bearing in mind unless you have camber arms on the rears, as you lower it, it will camber in a few degrees. Fronts can be adjustable through most aftermarket suspension types by around +/- 2 degrees.

So your 18x9+25 is great for the front, and depending on how much you lower it will depend on the amount of stretch you will need. If you want to be eating gravel, you will probably need 225s on it. Which is a fair amount of stretch.

Rears - These will be very close to the suspension, especially if you don't stretch the tyres. If you want 18x10 badly, you need an offset of 30 or less. I had 18x10.5+30 with 245/40, and it fit, but I don't believe there was much clearance AND it was sitting around 5-10mm outside the guards even with around 2 degrees of camber. Your 18x10s will sit 15mm INSIDE the guards, even with 0 camber, which in my mind defeats the purpose of having a fat rim and tyre combo.

Go 18x9+25 all round IMHO. It will be a safe choice, and you can put fatter tyres on the rears if you needed to.

18x10+41 is 10mm further into the guards than 9.5, I'll be running a 265 tyre, that's pretty much the biggest I'll fit.. I'm not going ridiculously low probably keep it around 110mm off the ground, so that should be okay there... If I get these wheels and worst case scenario I'll just have to run spacers I guess

I've been rolling around with stretched tyres on my 33 for a while now, haven't really had issues but just for track work stretched is a no-go so I'm looking into some semi-slicks.

9.5 +22 on the front

10.5 +30 on the rears.

Looking at getting some 265/40R18 for the rear, what's my best bet for the fronts? Got 225's on there atm I think, thinking they might need at least 245's but unsure what to look for. Anyone got a good idea of what will work best?

To run those sizes without stretch you are going to need to raise the car up, it won't be able to sit as low as the tyres will be outside the guards.

Correct me if I am wrong, but I would run 275s on the rear, more traction the better, especially for track. And 255s on the front. Not sure how much stretch is considered stretch?

[ECR-033]

I run 265 on a 10.5 and there is still a little stretch. 245 on 9.5 wont be flat either

18x9.5+12 on a r34 gtt with rolled guards and adjustable coilovers - on the rears. (Fronts I am going 18x9,5+20)

I had 18x10.5+30, and that was poking around 5-10mm with natural lowered camber, I feel the +12 will be too much. Anyone else had experience with this aggressive offset?

Was running 245/40 to fit the 10's in the guards.

I ran 18x9.5+12 all round w 235/40/18 R33 gtst

best offset for stock guards IMHO

guards are practically the same

Remember that going from 10.5 to 9.5 will pull the wheels in, if the offset remains the same.

ie) a wheel 18x10.5 +30 will have the same poke as 18x9.5 +17

So if you are going for 18x9.5 +12 it will poke 5mm more than your 18x10.5 +30

Car looks good, I want 'more dish' look on rears, so I will be going +20 fronts and +12 rears. Cheers for the help guys.

hi guys..

I need some advice here..

I have a dilemma to choose between 2 wheels options..

1. 18x8.5 +30 front with 235/40 and 18x9.5 +35 rear with 265/35

or

2. 18x10 +25 all rounds

which types are the most suitable enough for 1993 R33 GTST without any major modifications?

I have stock suspensions..

I'm sorry if I asked to much here, I'm a R33 newbie

[dontyellpl0x]

So your first option is conservative, same as what I'm running at the moment.. Front will sit in the guard a fair bit, rear will be flush with a little low.

Then you're second option is like bam! Super aggressive, especially for the fronts. Dunno if I've read anyone fitting a 18x10+25 in the front of a gtst

Do you want to drive your car or park it in a Maccas car park?

[alr33x]

18x10+25 won't fit with no suspension or guard work

[GTR-51R]

18x10 on a gts is a bit too aggressive. Mate was running 18x10.5 +24 and it was stuck out a good inch and a half

[alr33x]

It's very do able with the right components and set up

hi guys, thanks a lot for your advice..

so big no for 18x10, maybe I will take the option 1..

honesty I'm still looking for 17x9 but still don't get it here..

[joeyjoejoejuniorshabadoo]

heaps of people have done 18*10+xx it on stock metal... takes work though

fwiw it's less agressive than the 9.5+12's on my old car (photos in link on last page i think)

will be within around 5mm of the UCA

[GH05T]

with a Potenza 245/40/19, how large a wheel would you think will work with some stretch?

9.5? 10"?

im thinking of putting 10 on the rear and 9.5 on the front, with offset asside will the tires work or is that too extreme do you think?
