No I did not. I haven't touched any springs/shocks on my car since it arrived from Japan.

Aren't coupe always a little bit lower than sedans?

going from 245/45R18 to 275/35R19 does reduce the diameter by about 2.5mm which is not really much, and reduce the rolling diameter by about 8 mm only.

maybe the car had 350Z spring or a lowered spring, but the ride felt stock - no sign of aftermarket spring feel when it was on its OEM 18" a while ago. On 19" with lower profile it does introduce a bit more harshness because of the smaller sidewall...

It's also a very tidy auto so very unlikely the previous owner modified it in Japan with coilovers etc.

What is the correct size for rims + tyres for 19" on the Coupe?

Do a bit of research on g35driver.com plenty of info there.

Coupes can take a much wider wheel/tire combo front and back not to mention run really low offsets as well. You should take full advantage of this if you have a coupe. My advice:

1. find the wheel that you like

2. see if they are available in 9" front and 10" rear

3. choose an offset between +10 to +15

4. Then use the tire calculator to work out tyre profile and width

If you are looking locally at wheel shops etc, your choices will be significantly limited with regards to offset and width.

Try sourcing 2nd hand Jap wheels, there are quite a few around if you keep your eyes peeled.

Ok, been looking around.

If i decide to go from 225/40/18f to 245/35/19f, then i actually lower the ride height by about 40mm? Is that right?

They are both completely wrong profiles for a V35.

Use the calculator and stick in 245/45/18 as your tyre then compare it with profiles in 19 inch.

To give you an idea I'm running 245/40/19 and 275/35/19. Your overall diameter should be around 675mm on average +/1 15mm is ok

sorry n1sm0, 245/40/19 is the WRONG profile for V35 front.

the closest profile to stock 225/45/18 at the front is 245/35/19

the rear 275/35/19 you have IS the closest profile to stock 245/45/18

245/40/19 = 678mm

275/35/19 = 674mm

245/45/18 = 677mm

Don't argue with me :( I've done my homework, my tire guys agree with me and the guys in the US run this profile on their g35s :)

Our cars are rear wheel drive, best to compare it with the rears.

The guys on the G35 forums are saying the closest to stock is 245/35/19f and 275/35/19r but not on OEM 19" rims, only on rims that are at least 9"....

That's why i was wondering if i went from 225/40/18 (my current incorrect tyre) at the front, and wanted to get a 19" wheel+rim, then apparently the correct is 245/35/19f and 275/35/19r, and my question was - this actually lowers the ride height?

it won't lower ur ride height, it will give u increased ground clearance.

Rianto - the 225/45/18 & 245/45/18 combo is a bit of an exception to the rule, difference in OD is quite a fair bit and the 350zs came with these from factory, so I understand where you are coming from. But remember, our cars (sedan) came out of the factory with all 4 same width wheels and tyre profiles, so it would make sense to keep the OD front and rear as close as possible.

There are guys in the US tht run 245/35/19 & 275/30/19..they are the ones who dump their cars and like running skinny tires which looks good.

yep, but that's because the guy who's asking this question wants a 19" for his coupe, that's why I was referring to the staggered coupe sizes...

and very unlikely he's going for a standard OEM 19" from late model V35...

V35 coupe also come with this size from factory, exactly like 350Z, despite both 18" rims has 8" wide front and back... don't ask me why, I think Nissan should have made the front ones 7" or 7.5" as it shown on my OEM rims the 8" wide with skinny 225 tyre at the front caused the previous owner in Japan scratch the rims badly on japanese gutter.

My 18" have also bad gutter rash from japan because of this. so we all agree if i go 19 x 9, i'll try to get the 245/35 front and 275/35 back?

Hey Eldubb,

I'm looking at exactly the same issue too. So did you buy the 19" at 245/35f and 275/35r?

Also for the guys that know, the offsets that are supposed to best suit the V35 are in the teens, i.e. +15.

The guys at the tyre shop were offering me +30's offset, what is the difference? How will it affect the ride?

In terms of rim, they have Work wheels, which are beautiful, but a little pricey of course.

They also have Taiwanese made wheels, which look great, but a lot heavier and cheaper, what do you guys think?

Standard offset on V35 coupe is +30 front and back...

My aftermarket is +30 front and +25 rear. There is no need to go to +15... the more the difference in offset that can cause more strain to the hub, causing premature wear on hub bearings....

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
