the v35 are designed to have a staggered wheel setup. You can put the same tyres front and back at least 245/40/18 (i think, correct me if i'm wrong please) in order to get the closest Speedo reading. If you decided not to go to the stock spec it'll put your Speedo reading off by alot of margins.

the stock for 17" tyres on V35 is 225/50 17 and 235/50 17.

it's 225/45 18 and 245/45/18

I'm not sure what are you talking about being the front sitting little lower.

if you referring the 225 that's not the thickness of the tyres it's the width of the tyres. 50 is the thickness of the tyres.

hmm i have 20inch 255/35 on rear, and 225/45 on front...guess the 20inch would really through out the speedo.....

The tyre shop that fitted 225/45 on your 20s should be shot. do a search and look for a tyre calculator.

why does front and rear tire size for V35 coupe is different

For more rear end grip.

( is it stock standard)

Yes.

is it ok if I have 225/45/18 front and back ? ?

Your speedo will over-read more than it does already.

Your ABS may (but probably won't) trigger prematurely.

Your VDC may trigger prematurely.

is it for the purpose of aerodynamic that front is sitting little lower than rear?

Possibly, but probably not. The undertrays will have more of an effect on aerodynamics than the slightly raked profile.

Also, what's to say that the rest of the suspension isn't configured expecting the front tyre to have a smaller diameter than the rear, and is relatively higher on the body to compensate?

The front tyre has a slightly smaller diameter than the rear, so assuming that the rest of the suspension mounts are the same the front would arguably sit lower. However, to keep the chassis level I find it unlikely that Nissan would have done that.

Your speedo isn't that inaccurate. With your profile drop and relatively narrow width, your speedo only under-reads by 1.3% compared to stock (which over-reads a bit anyway).

f**k yeah. That width and profile is stock on an 18" rim - its way too high for a 20.

wow... what a heap to re-read and take in.

Just a couple of things that I didn't really see clearly stated;

Can everyone pls also remember the rolling diameter for one brand tyre in ANY size may differ from the same size in another brand.

The below information was posted and there was lots of good tyre calculators linked, however I just want to re-iterate it...

Tyre sizes work in this way 245/45/18 = Profile is 45% of the 245mm width/rim size is 18 inch/width is 245mm.

I always work out the specifics of the rolling diameter using the actual tyre size AND the Manufacturer Rolling Diameter info.

  • 2 weeks later...
what if I have stock 17" stock rims on and I changed to stock 18" rims. would the speedo overread?

Your speedo will not be out just because you go to bigger rims. What you need to make sure is you have the correct profile tires when moving to bigger wheels to keep the overall diameter same/similar. Thats what the tire calculator is for. Do a search.

OMG I NEED HELP.

I just got my V35 and drvoveinto driveway. I found out the mid-bottom scrape the driveway...

it is pain everytime goin in and out.

the driveway is like a dip. has a crest in the middle and thats where the scraping occur.

can I change the size of the tires(thickness ) so that i can rise the car i little. i think i need half inch only.

what would be a good size if i do it?

current on stock 18" , tires 225/45/18 front and back

Edited by tonich

To raise your car using tyre profiles alone by 1/2 an inch is going to be a HUGE change in rolling diameter. Extra sidewall height will make handling fairly wooly. Plus the fact your car will end up looking like a 4WD. Sunraysias anyone?

Time to move house ;) .

Can you approach the crest at an angle? That will normally help a bit.

I had the same problem as I have quite a steep driveway going down to the garage from the street. I nailed two planks of wood to the driveway to give me some more clearance and problem solved . Don't know if this would work in your situation.

Edited by Easy Tiger

cant do it at an angle, the the driveway is too narrow.

I will try the planks of wood. but I have to place the wood everytime go in and out. gonna to real hassle

I am not sure about 19" stock rims with stock tires. does it increase clearance compare to stock 18". i might be able to get a set

Edited by tonich

please confirm with me on this:

i have used calculator to compare current set up 225/45/18 to new tires 245/45/18.

the diameter of wheel increased from 26 in to 26.7 inch. does it means it will increase my clearance by 0.7inch/ 1.8cm?

if so what brand of tires should i get

or can i rise the height with this coilover.

link'

thanks for help

You are stuck between a rock and a hard driveway. There is nothing much you can do to the car without altering its handling characteristics or making it look stupid. Increasing tire profile to suit is not recommended. If you are currently on lowered springs, then I guess reverting back to stock suspension is one way to do it. Other than that, you will need to find a way to modify your driveway as recommended above.

I came across a similar driveway when house hunting a few months back, neither of my V's could get into it without scraping the bottom. Needless to say I passed.

Perhaps post a pic of the said driveway as well..and also do you own or rent this place?

i own a unit and i guess i shouldn't a car this size living in a unit. i now hunting for a garage near my place....

any suggestion on increasing the height with coilover? i dont mind if it looks stupid

Yes, You can go. I have coilovers sitting too low, I found the same problem with my driveway. So I increase it by 1 inch. no problem after. LOL, do looks not as good as it used to be, but as long as it do not strape my chasis.

Cheers

any pictures my friend? how much it cost and brand?

Sorry mate, no pic so far, I was on work.

Brand is BC racing, F 8kg R 6kg, I set it to the softest. not to much different with factory on comfort but do corner a bit better.

Price is not bad. Send me PM for details. I don't want put here as not sure whether it is proper.

    • A realistic expectattion of how long it has to last also comes down to.... when do you think you will be banned from registering and driving old petrol powered shitters? It's 27 years since that thing was built. It probably rusted out 15 years ago. It was probably repaired and looked OK for another 10. If you do a similarish bodge job now, or perhaps slightly better with some actual rust conversion and glassing, then.... get another 10-15 years out of it, after which you'll only be permitted by the CCP to drive electric cars manufactured in their Shenzen zone anyway. 
    • Let me assume that the concern over a manual ECU is that the NeoDET that you have was an auto and has an auto ECU. That ECU will not be a problem, but you WILL have to Nistune it. And you would have to Nistune it even if you had a manual ECU, because the turbo ECUs will shit the bed if they do not have all the things that they were told they have to have, to be happy. The big one being the TCS CU, which you won't have in your car. Anyway, with an auto ECU (which I have running my originally auto NeoDET in an R32) Nistune allows you to put in a Stagea image which doesn't panic about the absent TCS, and allows you to override a whle bunch of other annoyances that would otherwise see the check engine light on 100% of the time. Also, you can't wind up the power very far on the stock NeoDET ECUs without Nistune, because the boost sensor gets in the way. Nistune allows you to push that problem much further up the dial. Do you even have the boost sensor with the engine? Without it, you are SOL and will need an aftermarket ECU (or to find a sensor somewhere, god knows where). I can't tell you what the wiring loom differences are in a 34. But what Duncan said above needs to be considered. When you say "loom", does that include the transmission loom? Because you will need to swap out the auto tranny loom for the equivalent manual loom, and get rid of the neutral/park start interlock (basically hot wire it).
    • I have had the r3c in for years now, maybe close to 7 years and it has never missed a beat, anyone can drive it. Super easy to drive around town, the hotter it gets does get a little hard but it holds the power easy as 
    • Shit thing to find eh? I guess the big issue is that whatever "fix" you do now, it might slow the rust down but won't fix it. I just wanted to add that in no way is fixing sheet metal in 3 dimensions the place to start with welding....that is a pro only job because its too hard to work out where things should be, let alone doing a clean enough job that it can look OK and still be strong too.  I needed to get a new rear quarter panel on the GTR and it took a pro weeks to get the old one off cleanly, new one on in the right place and looking somewhat like it should have with most of the previous connecting panels in place. Gluing a couple of bits of metal together with a welder in the garage is doable, but that is totally different to doing panel  replacement
    • This seems to be a very popular swap since all the turbo skyline prices went through the roof! I'll let someone more familiar chime in, but I understand that yes you probably want to swap the loom in to swap out the auto TCM stuff. You should not assume everything just plugs in either, you need to check at least the ECU wiring diagram for any differences at the plug at the left headlight and probably the ones near the ECU that join the dash loom too
