Given that 595 RSRs appear to have some weird compatibility problem with R34 GTR rims (apparently the tyre cant be fitted to this particular rim) i'd like to know if anyone has fitted FZ201s to them before I buy a set...

I have *not* fitted them. Tyre shop (very good one) managed to get one on a rim using over 120psi to seat it before the manager caught them using that much pressure lol.

My theory is that it is a very aggressive tyre bead shape, combined with a very aggressive rim shape. I later fitted Federal 595SS to the same rims no problem, I've fitted FZ201 to 2 other sets of rims, and obviously billions of people have fitted tyres to R34 rims. But the combination just does not happen.

BTW federal were great about the problem, sent a tech to the tyre shop to check it out, and swapped for another tyre at no cost.

Thanks for the info Duncan. I guess i'll just try cheapo R888s as my first R specs then, unless anyone wants to suggest something else in the cheaper end of the scale in 255-35-18s.

ahh this won't help either....but I've heard nothing good about 888 under heavy cars like GTRs.

If you can't go different rims or a different size FZ201, I'd look at kumho v70a as the next best reasonably priced semi.

here you go

Hi everyone,

Mick from Federal (NTW) here. Firstly I would like to thank everyone who has ordered Federal Tyres through the NSW Club, we really appreciate you and the club supporting Federal Tyres!

I have some important info for anyone considering purchasing 595RS-R tyres for their R34 GTR wheels that I thought I should share... It appears that there is a compatability issue between these particular wheels and the way that the sidewall/bead area of the 595RS-R is constructed.

There have been 2 members who have recently purchased 255/35R18 595RS-R's for their R34 GTR wheels and unfortunately on both occasions the tyres have either been extremely difficult to fit or have just not gone on the wheel at all. We now know that the reason for this is that the 595RS-R has a more "aggressive" bead angle which is built into the tyre to help it seat on to the wheel a lot firmer than regular street tyres (this reduces the risk of the sidewall and bead area being damaged under extreme loading commonly caused by track driving) normally this would not present a problem, however we have now realised that the R34 GTR wheels were also built with this in mind as they have a bead seat area that adopts quite a large and aggressive bead retaining lip (which also helps keep the bead in place a lot firmer than normal). When these two aggressive bead areas are put together it makes the tyre extremely hard to fit to the wheel (not impossible though) and it is only made more difficult by the extremely stiff steel reinforced casing in the 595RS-R.

This issue is only evident when these two products are put together (R34 GTR wheels and 255/35R18 595RS-R's), we have not seen this occur with any other sizes of 595RS-R's or even with the same size on different wheels so don't be discouraged as this seems to be strictly limited to this particular combination of wheel and tyre.

Please don't hesitate to ask me any questions, I'm happy to answer any queries or concerns by either PM or within this thread.

Once again, thankyou for supporting Federal Tyres, we hope that we can continue to support SAU NSW for many more years to come!

Cheers,

Mick

bloody hell...thanks for finding that post Zeb.

Important point....the issue was with 595RSR and R34 GTR rims, not FZ201.......so take back all my earlier comments in this thread!

I've used FZ201 on 2 other sets of rims without any problems, and was very happy with them, especially for the price

Adam it is definately the same Mick (NSW club member), he was super helpful when the issue happened.

Kind of glad you brought this up, i was planning this as my new tyre/wheel setup, which leave me wondering what tyre to use instead. Ku36's dont come in 255/35 so anyone got any reccomendations for a street tyre. Cheers

FYI, Mick doesnt know if the FZ201s will fit and has not agreed to take them back if they dont. Thats not good enough for me so I will go for something else.

Hi guys,

Mick from NTW (Federal Tyres NSW) here... I apologise for not getting involved in this subject sooner, I have been reading your posts but unfortunately havent found the time to reply to them all.

Hi Adam - When I read your post (above) I realise that there must have been a break-down in communication and I apologise... I do remember discussing these tyres with Owen when he contacted me to see if they would fit on to your rims but I don't really remember the exact wording in the discussion so I'll try to clarify for you now.

What I would have meant to say is that it is our company policy to not take returns of special order tyres (tyres that are not a regular stock line) which the 255/35R18 FZ-201's are... However in this case I am happy to make an exception as we are unable to advise whether or not they will be compatible with your rims.

Adam, I don't usually do direct sales as I primarily work in marketing, but will be happy to personally look after this order from start to finish for you if you choose to go ahead and will be happy to talk to you directly over the phone or via e-mail when it comes to fitting the tyres (whether they do fit the wheels or not).

I will ensure that if the tyres do not work on your wheels and they are in returnable condition (no damage to bead area or sidewall) that you get a full and prompt refund.

Again, I'm sorry for the break-down in communication and I hope that we can still help you out with some new rubber! :)

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.

      I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
