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.

tires are 235/40 front and 245/40 rear

soon to be a 225/40 front and 235/40 rear once i decide to go get them

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

cheers :action-smiley-069:

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

    • I was using the wiring diagram I have So 12.74V is coming into the rear Fuel Pump relay as I measured.  When I turn the key to ON im getting 0.6V to the Fuel Pump plug; which i assume is backfeed voltage and doesnt include the 12V from ignition power.  The rear relay is working and being triggered.  From the diagram I clearly see the rear relay 80 = Rear Relay going into the Body/H loom (R-27) 27 = Fuel Pump plug going into the Body/H loom (T-20) 40 = Short Connector (R-27) I'm reading 12.74V on the blue/black wire which is the power for the Fuel Pump   From this diagram I can see the Ignition relay goes into the front and up to the ignition  2 = Fuel Pump Relay <1M> (R-27) 37 = ING Relay <1M> I started from the pump using this reference Which the way I read it (referencing Nissan wiring color codes) is: Pin Wire Color Function 1 B/P (Black/Pink) Ground 2 L/W (Blue/White)        ECU Trigger 3 SB (Sky Blue) Fuel Pump 5 L/B (Blue/Black) 12V Constant Tested SB to SB on Fuel Pump for continuity - confirmed Tested negative on Fuel Pump to 12V battery and L/B - confirmed 12V Pulled the relay putting 12V between Pin 1 & 2 and testing continuity on Pin 3 & 4 - confirmed relay   So that has me looking at this part of the circuit to understand whats happening here...and im still confused. From best I can tell; the disconnect is back to my previous diagram; between Ignition Relay and Fuel Pump Relay...which yet again; afaik is where the immobiliser should.    Thats what I was trying to explain to GTSboy; im not trying to fix it myself; yet I seem to have to get a Masters in Electrical Engineering (while im busy doing my actual job of DevOps & Cloud Engineering) somehow.  I just wanted more expert opinions; or more so that what I tested is correct and proves it to something around that area; to go back to the alarm tech (for a 3rd time) that he needs to fix it. He keeps telling me its not the alarm. He lives on the complete other side of the city so i understand not wanting to make a trip but as I said before if its the alarm it should be up to him to fix it. But he's adament its not; even though I pointed out the FP was immobilised through the original alarm. To my mind; it seems that the ECU is sending the signal; but the ignition is not getting 12V down the line.       
    • Maybe also really stiffly sprung track cars. Get the inside wheel up in a corner and all the fun stops. Also me sometimes (rarely) when I have to stand on the brake to convince the diff to drive the wheel that is still on the ground when I'm trying to diagonally get over severe driveway entrance, etc.
    • I feel like I'm missing something. You had an authorised installer come out and install a new alarm. Post install the car doesn't start, and you aren't getting the installer back to fix what they did wrong?
    • So either way it is gearbox out and look what is wrong?  I know about the input shaft bearing. Even before swap/new clutch the it sounded exactly like this: So is that inout shaft bearing or the other was installed backwards?  And can some please tell me the part number for that input shaft bearing? The gearbox is small box from R34 N/A and number is FS5W71C. Thank you  
    • I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'
