Im in the market for some new rims...at the moment i have stock 18s on and what i know is:

If i want another set of 18s without hassles, i need the rim to be 18 x 8, 5 x 114.3 bolt pattern, with offsets of +30mm.

But what if i want 19s to fill the gap in my arches a bit? What size rim do i need without having to get into buying spacers and doing coilovers and all that rubbish that costs extra? Can my current yokohama tyres that i bought recently be stretched over a 19 inch rim without too many problems?

I dont want to lower the car any more (which isnt much at all) because it barely gets over those cement parking blocks around brisbane and at work.

oh my oh my... rule # 1 - never stretch a tyre into different size rims... you'll break the bead around the tyre rim and it'll just a matter of seconds before the tyre sidewall gets rip apart... mind you that V35 is a relatively heavy car - around 1700kg - they will put more stress to tyre than a 900kg Toyota Starlet. so play it safe....

well if you know your 18" offset, PCD etc, just find a set of 19" with the similar spec in terms of width & offset. anything around 1 inch variance or around 5-10mm offset variance to the stock one might fit. rear is wider so they're easier to fit more aggressive offset at the back than front, as the front you need to find as close possible as to stock so when you turn your tyre don't rub the inner guard, and shave off the corner of your tyre, or causing dented guard.

if you don't lower your car pretty much anything would fit...

here's 19x8.5+30 & 19x9.5+25 look on my car...

V35 are huge car, and even 19" looks small on it. But going 20" or over means you get hardly any sidewall protection over potholes, and will likely be bending the rims if you're not tip-toe-ing around avoiding potholes while driving...

Firstly do you have a coupe or sedan? They are both very different when it comes to what size and offsets will fit.

Secondly you will not reduce fender gap by getting bigger wheels. Bigger wheels require a lower profile tyre to maintain the rolling diameter. Lowering is the only way you will effectively reduce this gap.

I've got a coupe but i dont like the gap - i guess i'll stick with 18s though and see how it turns out...

thanks for the info rs73, i guess i wont be trying to stretch them then. I'll stick with my yokohama's on 18s, new rims will still look 10 times better...i like your ride height and your rims look nice.

what tyre profile are you running currently? You shouldn't be that low and scraping on stuff with stock suspension? If your tyre profiles are currently wrong, that might be the cause. I had this problem once when I first got mine, it was scraping on the slightest hump. Dealer had put incorrect/lower profile tyres on. Corrected this with new tyres and problem solved.

I think the profile is fine...running 225/40/18 on front and 245/40/18 on back.

Just the front lip always barely scrapes over the cement blocks by 1mm, literally. There's a picture of my car under the detailing posts but doesnt show too well the right height i think.

there is your problem, you are supposed to run 225/45 and 245/45 in 18s. This is the closest to factory OD and is what the 350zs run on with oem wheels. Put those numbers in a tire calculator and you will see how much difference it mAkes to closing that wheel gap and also increasing your ride height.

Yes. On 225/45 & 225/40, the sidewall difference is 5% of 225mm = 1.125cm

On 245/45 & 245/40, the sidewall difference will be 1.225cm

that would raise your ride height by that much. that's probably just what you need to clear gutter and sidewalk, driveways etc.

Will it REALLY make that much of a difference?

Yes it will. Your speedo will be out of whack as a result and also in QLD, its illegal to go over +/- 15mm your overall rolling diameter. Keep that in mind.

The profile you are currently running will suit 32,33,34 as they have a smaller OD from factory.

Thanks for the info lads.

Danny - i meant i just replaced my 2 fronts for $400 each for 225/40/18. yoko's arent cheap are they :laugh:

Looks like i've be getting a whole new wheel+rim package. Shame.

Eldubb - before you go changing your wheels and tyres let me know as I will be selling both my Volk and SSR SP1 very shortly.
