wrong tire sizes. with that offsets you can run a 275 30 20 front

rear you can run a 325 or 335 25 20

do not run a 30 profile up front unless you drop to a 245 or 255 which would be too little for a 20x10.

actually you could run these tires which are great tires.

Tire Search Results

the rear would use a spacer and look a bit bulgy.

To be honest, I dont like a 20x11 wheel. The ideal size for that is a 305/25/20 or 305/30/20. Both arent exactly correct for a Z. the 25 profile is too skinny the 30 profile is too tall.

IF they are custom wheels your getting, go for a 20x12 wheel in the rear.

if you get to pick the offsets and you want to run the tires mentioned above without rubbing or modification you will probably have to go:
20x10 + ~35
20x12 + ~24

So...on my 350 I had Volk GT-S that were 19x9.5 +18 F and 19x10.5 +17 R with 245/275-35's and I really liked the set up. It seems like our 370's have much more room. So with that said, I'm looking at doing a 20x11/20x12 set up on my current car. I don't want to have to use spacers, so what offset would you guys recommend. I want them as flush as possible with little to no "poke". Oh, and it will be pretty low on KW V3's.

again if you look above at my pictures.

thats 20x10 + 27
20x12 +20
with 275/30/20 front and 325/25/20 rear.

That said, the wheels are now on a diff car, and hes lowered a bit and they sit perfect.

that also being said, the manufacturer doesnt make those sizes anymore. best match is michelins 285/30/20 and 325/25/20

to run those. I'd recommend a 20x10 + 35 front and 20x12 + 23 rear.

At oem suspension these should poke a bit. lowered they should sit right. I'd still recommend camber arms just to tweak em perfectly.

Running a 11 front wheel wouldnt benifit you much as you'd have to run a less wide tire.

P.S im estimating the offsets a bit due to the fact that I believe the Mich's are a tad bit wider than the DW's i ran. How much wider i dont know. Thus you may need the camber arms to tweak it.

We have more room on the rear but less room up front. Atleast offset wise. You will have to go with like a +35 offset on the front to even get close to fitting. +25 on the rear and you should be fine but don't quote me on that. Only a few people are running that wide.

Thanks for the input guys. I saw the pic of W.O.W. 370z's car a few days ago and LOVE that look. But i don't think i'd ever want to go 20x11/20x13, I still want some functionality. And i'm not stuck on the sizes I listed earlier but I definitely want to go a little wider than what was on my 350.

Some function?

I have more contact patch than probably anyone even with -2.5 camber. Just right for the turbos. :p

I am always amused by the misinformation on here sometimes.

Only Z with 13 inch wheels and 345s. Its all about the offsets!

Carry on!

^ Agree

When you coming back to Miami when I will be here!

20x13 + 30 will fit a 345 quite easily. maybe up to a 33 offset depending on the actual width of the tire.

main reason i chose 325 and a 275 is that those matched the OEM tire sizes the closest. (overall diameter)

I know and your setup was also one of a kind.:tiphat:

FYI My post was directed at some other particular people, not you!

I know. Just saying that specifically for other people. As also mentioned above i dont like the 305/25/20 as its quite a bit shorter. Personally i'd rather go taller than shorter. At least you'd have a better ride and less chance of damaging the rim.

Ha I'll be the first to admit that I'm not the most informed person on the forum. And I, in no way mean any disrespect at all. I think your car is sick and I love your wheels, and if you were still looking to sale them I'd definitely try to buy them.

If its as functional as you say and you don't have much problems running a wheel that wide, then that's music to my ears because again I love your set up. I've spent countless hours trying to find a wheel I REALLY liked, and then I saw yours. Guess I'll give ISS Forged a call on Monday

So, thanks to member Daisuke 149, I was able to get some recommended tire sizes of 275/30/20 and 335/35/20 on 20x10 and 20x11 rims, respectively. (Thanks again Daisuke!) I was wondering if anyone could tell me if i will have any issues lowering on springs between 1-1.5 inches in the front and back with this setup. Thanks in advance for the help!

335/35/20 must be a typo.


335/25/20 on a 11?

That is way outside recommended range for a 11 inch wide wheel IMHO.

Good luck!

What size tire would u recommend for the rear? The front size looks correct though? Do u see any issues with the 1 inch drop?

i agree. 335/35 is a huge sidewall which would never fit. 325/25 or 305/30 are whats recommended for 11. if you go to any tire manufacturers website and look up the sizes on tires, it shows you recommeneded wheel widths that those tire sizes shoild go on.

If you want widest wheel possible, then 325/25/20 which is still too wide for an 11 but doable.

Ok thanks guys.... I appreciate the help..... One last question..... Any way to know if an inch to inch and a half drop will cause any issues with this setup without just trying it?

if anything, the drop will help your cause with some camber. now a drop at adjusted back to stock specs could cause you issues but you shouldnt have to run too much camber.

Help! Will it fit?
Currently running 245/40r19 and 275/35r19
looking to bump up to

19x9 +32 275/30r19
19x10.5 +32 295/30r19
Will it fit w/o rubbing?

Or would a

265/30r19
285/30r19

be a better set up?

A little offset help...

For the front it will be a 9.5" wheel, they offer a +12 or +22 offset... what one? The rear will be a 10.5", same question +12 or +22?

Thanks

I'm running 9.5 with +20 on front and 10.5 +7 on the rears. Front only rubs on VERY large bumps on the fender liner. Rear clear fine. Depends on how much camber you are running on whether the +12 would fit up front but definitely +12 on the rear.

Ok. So most likely 22 on the front. Do you have a spacer on the rear?

5mm. the wheels are +12 so with a 5mm spacer the effective offset is +7.

Ok cool. Thanks.

So I'm switching from the base (non-sport) tire/wheels 225/50/18 245/40?/18 to the sport rays w/ hankooks off of ishmaelz. The specs were 245/40/19 an 295/30/19.

I was wondering if I can just simply switch them without having to worry about spacers, otherwise, I might just have to buy 20mm for both the rear and front.

Any suggestions/opinions?

Of course they will fit. There is no difference between clearance from sport and base. Just wheels themself. 20mm Spacers will make it flush to the fender but otherwise there is no reason to have em at all. Hell, even the base 18's clear the Akebono sport brakes without spacers.

say I didn't get the wheels from ishmael, but I decided to go for a higher rim size..
What I'm currently looking at is this:
20x9.5 +22 / 20x10.5 +25 with either

255/35/20F 285/30/20R

or

255/30/20F 305/25/20R

I think that I'm gonna have some slight rubbing issues on the front. As for the back, I'm thinking it should be fine.

run 265 front.
you may end up getting a 5-10mm spacer for the rear.

Hey guys! Im looking to purchase new rims and just wanted to double check with the group that this setup will work without rubbing. Lowered on swifts...
F 20x10 ET25
R 20x11 ET10
Thanks in advance!

Will Enkei NT03+M fit our Z? I haven't seen any 370z with them. Sorry I have little knowledge about wheels and tires. The biggest size they run are 18's.

Bump :hello:

A friend has a 350 and he wants to buy rims and tires. He wants all the same size tires so he can rotate them. I think he wants all of the rims with the same offset and put spacers in the rear so they're not tucked under. Something like 18x9 front and rear with stock height.

Check the My350z.com forum. Offsets on the 370 to the 350 are completely different. Most guys on here won't be able to inform your friend.

I have 19" rays, I want to get 20mm spacers all around and swift springs, I should have no problem with rubbing!??
Thank you!

your good to go no rubbing :tup:

Can't find what I'm looking for so I was wondering how an 18x9.5 +15 would work out up front if I'm planning on going with a 275 up front. I know I may need to jump down to a 265 but dont really wanna go to a 255. I am stock height right now but will be on Swifts without a doubt soon. Stock camber as well. Any suggestions/ideas/pictures of this setup actually working?? Thanks guys!

275 up front on a +15 = you'd need camber...
265 you'd need camber..

you need at minimum 25 offset. and then a tire that isnt as wide as other manufacturers or rounded. I ran a conti DW 275 on a + 27 offset oem camber and suspension could have done a 285 i think. but if you get like a michelin tire you'd prolly need a + 30 to run a 275.

Damn that's what I was afraid of.
I guess either ill look for a smaller tire for now or look into a different set of wheels. You think maybe a front fender pull would work? It'd need a bit of pull huh.

the front fender could be rolled and you could squeeze a 265 in there maybe... maybe. I dont think you'd have to pull.

Id rather spend the money on front camber arms than pull or roll tho.
