Just wondering why those running 18" rims are using 235/40/18 tyres as opposed to 22/40/18 tyres that have a closer rolling radius to the standard 225/50/16 tyre, apart from the fact they are wider?

Wouldn't the 225/40 have a narrower sidewall than the 235/40 - this is purely visual difference

Yes, yes and yes. However, the 235/40R18 is far more common, therefore a wider choice in product availability and, they are generally cheaper.

Does anyone think its a stupid idea to run different widths front/back. Ive found some cheap wheels, but they are 7.5 fronts and 8.5 rears. As long as i match rolling, but its never PERFECT....not sure what to do :)

you'll eventually burn out the transfer case,as it'll be constantly compensating for the different rolling diameters front-to-rear.

as for the std S2 17" wheel,I'm afraid I can't help with this,as I have only a compliance placard as well...

OK, it's taken me a while, but I pulled a wheel of the series 2 S (with the standard 17inch wheels) today.

The Rims are 17x7JJ 30

My 8inch rims (standard) from the R34 GTX turbo don't fit - well they fit, but there is no way I would have taken it for a drive as the rubber would have been rubbing quite a few things...

Hope that helps.

That's what I've got on mine. 8inch would fit with a bigger offset.

The ATTESSA handles different tyre diameters due to wear ie; you can have barely legal tyres on one end and brand new tyres on the other end. That's a 6 mm difference in radius, 12 mm in diameter and 37 mm in circumference. That's covers most width profile differences easily.

Real world, my Stagea doesn't like 225/50/16's on one end and 245/40/17's on the other end. After less than 1/2k driving in a straight line, the ATTESSA started to shudder. I had to turn the steering wheel (for imaginary corners) to stop the shudder. I must have looked like a lunatic, warming the tyres up driving down the freeway.

:huh: cheers :P

i dont think i have quite made a post in here yet so i will

18x9 +0 offset with spacer to clear GTR brakes

18x10 +20 no spacer

Problems

if you do not have rear toe arms and camber arms, going low is a problem in the rear for sure.

You need to put a decent roll on the rear, so you can get as near to 0 camber static as possible to keep from hitting the coilovers. as wwell as a stiff springrate and sway bars will help this fact as well.

Front....well im still working on that.

but they kinda fit. I spraypainted the inner well so i can find out where it is rubbing, right before full lock it rubs somewhere, but at full lock it doesnt, so i have to figure that out.

other than that

at my current height, no big problems, or at least nothign that a little thinking and money wont fix.

I have an RS Four S, Series 2 manual with the factory 17's.

Can confirm the wheels are 17 x 7 with 30 offset.

The tyres are 215/50 R 17.

I was browsing the Work Wheels jap website and they have a recommended fitting guide for the Stagea, incidently every listing shows the same width and offset for both front and rear wheels.

Here's what they say will fit:

16 x 7 35 225/50 16

17 x 7 35 225/45 17

17 x 7.5 28 225/45 17

17 x 7.5 30 225/45 17

17 x 8 30 225/45 17

17 x 8 32 225/45 17

17 x 8 35 225/45 17

18 x 7.5 29 225/40 18

18 x 7.5 30 225/40 18

18 x 7.5 31 225/40 18

18 x 7.5 32 225/40 18

18 x 7.5 35 225/40 18

18 x 8 30 225/40 18

18 x 8 33 225/40 18

18 x 8 35 225/40 18

18 x 8 38 225/40 18

19 x 7.5 28 225/35 19

19 x 7.5 32 225/35 19

19 x 8 26 225/35 19

19 x 8 29 225/35 19

19 x 8 30 225/35 19

19 x 8 32 225/35 19

19 x 8 35 225/35 19

19 x 8 38 225/35 19

I assume theses sizes have been tested (at least in theory) on standard vehicle. If you have suspension mods some of these sizes may not fit.

Hope this info is helpful. :)

Rather than start a new thread on the same topic, I thought I'd post in here...

I'm up for new tires soon, and the placard on my door also says both 205 60R16 or 225 50R16 (which I have at the moment).

The current tires are cheap (simex) brand and I'd like to improve this with my next set. But I need some info.

The current tires' sidewalls bulge a fair bit which I presume would affect handling negatively. Would a better quality tire improve this at all?

And I'm not looking at paying a lot, just want tires that aren't too cheap and nasty and aren't too expensive either (say in the $150-200 range per tire, but hopefully closer to the $150 mark).

I'd prefer longer lasting tires than super handling...

Any recommendations? I figure its probably best to stick with 225/50's as thats whats on there now. Not sure why they list 2 different widths anyway...

And can anyone confirm what pressure they should be at? I've always filled them to 38-40psi thinking that was better. Never noticed that the sticker says 29 & 32 psi Is the sticker wrong?

cheers :D

BTW

a good stagger for the stagea if your interested in a 9 inch wheel is

9 +30 rear

9 +20 front

it clears almost everything, depending on your height you might want t hammer up the inner lip on the fender

but other than that your good

i personally fill my tires to 33-35psi depending on where im going

i read all of this and still dont have a clear answer. i probably missed it. so will any rim (in skyline stud pattern)17 or 18 inch diameter, 9 inches wide with a +30 offset fit?? or do u need a different width and offset front to rear. id like to have the same width and off set all round i can rotate the tires, but if i cant then i wont worry about it. or should i just use a narrower rim like 8.5 or 8 inch

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
