depends on the tyre and rim, i run around 30 front and rear for drift, people often run higher psi at the rear thinking it will last longer, but it actually delams the tyre quicker. but it comes down to just having to test, go out, have a feel, play around with psi and try again.

17x8 225s stretched

lol, 225's aint a stretch on a 8", with road tyres its gonna flop around a bit, id probably be running around 35psi, but thats just me, i hate the feeling of the front tyres gliding over the road and not grabbing even if it means the sidewalls arent as rigid, saying that i dont run crappy street tyres on the front so i usually dont have that problem. get some decent performance tyres with rigid sidewalls, best of both worlds.

im assuming you are all just running air in your tyres?

i have nitrogen in my tyres, which is not supposed to expand as the tyre gets hotter

so i have my tyres set at 38 when cold (234/45/17)

just for street use.. i find it really good because when ever i check my tyre pressure it never changes.

most tyre shops charge about $5 a tyre to fill them with nitrogen

Nitrogen still expands with heat, let's face it air is ~60% Nitrogen. The big advantage is the lack of humidity, the water (H2O) splits into H and O and that increases the expansion in the tyre. Dehumidified air doesn't expand much more than 100% nitrogen.

Just after some input

I have FEDERAL EVO 595 SS tires on my R33 GTR wheels which are 17 x 9 - I'm running 215/45/R17 tires

I have had both front wheels balanced but it vibrates a fair bit, then I dropped the tire pressure from 34 to 30psi and its quiet a lot better

I realise some of the vibrating issues may be due to the stretch of the tires on the rim but what would be a good pressure to run these wheels at?

  • 6 months later...

I run about 40psi front and rear in my 235/45r17's. But I also do a lot of highway driving.

I find that if you keep an eye on your tyre wear you will be able to tell if the pressures you are running are too high or low. Then you can simply alter it accordingly.

However if its purely grip that you want then all of this probably wont help you lol. I'm just more interested in tyre life as I don't drive like I'm on a race track all the time! :)

    • Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!

    • Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.
    • Hope the cans went down well at least 
    • 255 can't go wrong with the price.
    • When I was replacing my pump due to being stranded in the wrong state, I went with the Deatschwerks 320lph kit. It is a direct plug in to the stock wires, harness, everything. It comes with a plug... but you can plug the OEM plug directly into this thing. https://justjap.com/products/deatschwerks-dw300-fuel-pump-nissan-s13-silvia-r32-r33-r34-skyline-c34-stagea?currency=AUD Downside: Won't actually flow that much on boost if you want to push it on E85, but it's comparable to the 040/255 etc. Little more actually.
