Definately 245/35R19 to keep the correct outer diameter. 245 on a 9.5 looks just right IMO too. Not muffin topping and ever so slightly stretched. That's if it's an R33 or R34. R32's have a different outer diameter. 255/30R19 would be right for an R32.

265's

the very slight stretch makes them look pretty good i think

There isn't gonna be ANY stretch with a 265 tyre on a 9.5" rim.....

When it comes to comparing physical tyre widths between brands, there isnt really any way to say exactly how wide they will be without actually getting out your tape measure and measuring the sectional width of the tyre.

There is no exact common rule that all tyre manufacturers stick to when it comes to how wide tyres have to be.

Tyre widths (such as 235, 245, 255 etc.) are only comparable within each individual brand... I have seen two tyres of exactly the same size (275/30R19) in two different brands that were almost an inch different in width.

If you are really concerned about the physical width of your next set of tyres then your best bet is to find out which brand and model of tyre you want, then go to some local tyre shops and ask if they have them in stock so that you can get the actual width.

As for the overall diameter of the tyres - find out the original size that the GTR came out of the factory with, work out the diameter in mm (there are sites on the net that will calculate it for you) then try to get as close to this as possible with the new 19" tyres, for example:

---- 245/45R17 = approx 652mm diameter

---- 245/35R19 = approx 654mm diameter

---- difference = 2mm.

Hope this helps :)

      Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.

      Recomended Coolant For Gt T R34

      By silviaz · Posted

      What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.

      Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!

      R34 4 door side skirt identification

      By Rezz · Posted

      No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
