Hey guys, the time has come to change the tyres on the GTR and I currently have 256/35-18 but am thinking I would not mind going a little wider and with a little more profile. The car sits quiet low and if I decide to put my coilovers back in then it will sit even lower so I think the profile will give the car some much needed height. Apart from that I think the 40 will make it a little nicer to drive everyday?

My main question is do you guys think they will fit or should I sick with the 256/35/18? From what I can gather there will be approx 3.8% delay in the Speedo from stock but that doesn’t worry me too much. I just don’t want any scraping.

Thanks in advance.

PS: wheels are 18x9.5 (not sure of offset)

I think the offset is +18

There are a few markings on the back:

18x9J 18

H/2

AVS18-1

94/5

The wheels are Yoko AVS model 6.

Thanks in advanaced.

For 18 x 9 +18 rims, i suggest you stick to the 265 wide tyres.

If you want, get a wider set of rims 18 x 10 with a lower offset, but i'm pretty sure you'll have to roll your guards then.

This thread might be quite useful actually.

The guy at the tyre shop i have been using said he thinks they should fit, BUT if anything they may scrape at the front on full lock for the first few k's so after a one wheel dummy fit we went ahead and did them. Amazingly however they do not scrape at all. I went on the dunlop website and 9" was the minimum rim width for their 275 so all is good I guess. I will let you guys know how i go.

Thanks for the input.

BTW: tyres are sp9000

I'm running 275/35ZR18 on my R33 GT-R. I get a bit of scraping at the front on full lock but i have no trouble with the guards and suspension travel.

I'm running Volk TE37 18x10.5, not sure of the offset, i bought already set up.

Guys I take back what I said! They to rub a little front and back (I think) I just noticed when I got home. Only on full lock on the front and rear plastics surrounding the front wheel, they are no where near the guards or any suspension components. I hope that helps people in the future.

To be honest I am quiet disappointed they run but I don’t think its enough to make a big deal about as its extremely small. The noise is so little that I could not even hear it. I think after a spirited drives the rubbing will go.

I cut out a few sections of the plastic inner, just to be safe.

      new 1.5 LSD issues/concerns

      sold listed as a Tomei LSD 1.5 Way For 1998+ Nissan Skyline ER34 25GT RB25DE w/Open R200 https://www.ebay.com/itm/174006114594?campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=&mkrid=711-53200-19255-0&loc_physical_ms=108689&loc_interest_ms=&campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=71883f2ccc571356e0a757bc7adfdde2&mkrid=710-53481-19255-0&loc_physical_ms=108689&loc_interest_ms= it went in like butter all gears, alignment, back lash etc, rotation and clearances correct, and if rolling all rotates smooth and free when coasting down road , clutch in or out over 10 mph smooth... its the binding, clunking and jerking from a stop that is most concerning, also seems like its going to tear the tires off in 10 miles of normal road driving.

      What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.

      new 1.5 LSD issues/concerns

      By JC71 · Posted

      looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
