Hi,

As for over / understeer does it make any noticeable difference on a GTST if fronts are either 235 or 245?

I read that most people recommend 235 at the front, so is there any downside to 245?

(Rear will be 255)

Thanks

Only issue is to make sure you have proper clearance between tyre and guard, and wishbone. That includes when the thing is on lock.

They are a front-heavy car and ultimately will benefit from a bit more rubber on the road. For 100 percent road use you may not notice a huge difference though.

Hi,

Thanks ..

The 245 do fit with just a slight rubbing issue on full lock and cornering on the right side only.

I could remove the splash guard or just tread that area with a heat gun and push/mould the plastic back a bit.

The wheels I bought are GTR wheels and came with 245 all round (but need to be replaced)

Rear is fine with 245/45, and 255 40/45 should just about fit without any drama.

Go the 245's on the front mate, you shouldn't have any issues. If you want to knock off some under steer, grab some stickier tyres and maybe dial in a little more camber if you can which will also help with guard clearance.

Yeah i have run all sorts of tyre combos and am in the middle of working on a new one... Tyre brand and type will make more difference than tyre width in a lot of cases...

On my street rims XT7 8.5f 9.5r

235f 265r worked well for street use

255f 265r worked well for street and some track

255f 275r worked pretty good but rear clipped the guard on big bumps and turns

Currently going 265f and 265r on GTR rims and that is a mission! These are proper semis though! :D

265's fit perfectly on BNR34 rims. I run them on my GTT (all 4 corners).

Hello,

Are you on r34 GTR rims or R33?

I got the R33 rims which are 9'' wide and I think the R34 ones are 9'' as well?

Hey mate. My R34 Gtt has R34 GTR rims (9in wide) with 265/35's all around. No issues with rim/tyre combo for me.

The R34 GTR rims are 9'' wide by 18''

But if you say 265 is no issue then that would leave me with more options.

Do you have a close up picture?

Is there any ballooning?

Last pic is of the same rim+tyre on a R33 GTR.

Hi,

I could go 265/40/17 at the rear but would have to roll the lips of the arches.

Then it would be 235/45/17 at the front to have the same diameter at both ends.

That combination is the same diameter as your 265/35/18 but on 17''

The trouble is, that there is a very limited number of tyres in 265/40/17.

http://www.tyreleader.co.uk/car-tyres-265-40-17/

So I am marvelling if I should not rather stick with 245/45/17 all round.

I'm unsure if 265 at the rear will vastly improve the ride / tractionbut it sure would have the looks ..

Here's how it looks with 245/45 .. needs to be lowered 1cm.

For track, the usual recommendation is to fit the narrowest recommended tyre for the rim. In many cases on a 9in rim this will be a 225, but you need to check what the tyre manufacturer says is the rim recommendation for the specific size. Eg, on http://www.federaltyres.com.au/tyres/high-performance/595 the options would be 225/35ZR18 225/40ZR18 245/45ZR18 255/55R18.

    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
