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

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
