with -1 camber up front? I dont have adj control arms, yet.

 

Without arms a 9.5 +15 works with a 265/35 with a 2 to 3mm pull on the fender, a 245/40 fits without issue.

 

Will this rub?

19x10.5 +22 F&R
255/35/19 F
285/35/19 R

My 2007 Z sits on Megan lowering springs (from previous owner) which is a 2" drop. I don't know the camber spec. Fenders are not rolled.

 

Hi guys. So I'm getting these Eurotek Uo07 19 in rims off eBay, they are 9.5 front with +12 offset and 10.5 rear with +22 offset, were going to put on 235/35 19 and 275/30 19 tires.
I did some research and found out they should fit in just fine might even without a fender roll. And today the costomer service people called me and told me I will have to get coilovers to make them fit or they would rub crazy with these 12 and 22 offsets.
To be honest I'm not an expert at all on these things so I'm confused not. He is actually trying to get me to pay a few hundred bucks more for some 30 offset rims that he says would not rub.
So need help guys! I'm not tryin to pay an extra thousand for coilovers so, is he right? Should I just go with some other rims with a different offset or should I just tell them to ship them out anyways? Thanks guys but I really need some suggestions on this.

 

Man I hate fitness problems. My doctor said to get my blood pressure down I need to start exercising more.


I don't see how coil overs will stop them from rubbing.


Are you at stock height already?

 

The real question is, are you lowered? If so by how much, plan on rubning camber?

 

Better question...why Eurotek?

 

Yeah that's what I said to him! Yes sir. all stock.

I am not lowered at all. Would consider a fender roll thou if necessary.

 

IDK... just kinda found them and liked the style, plus they are not that pricy, any better brands you suggest?

 

First off, you have a FITMENT problem, not a "fitness' issue. Makes the title of this post look DUMB. And if the Eurotek CSR says these wheels will not fit, why not believe him/her? Don't buy them- go back to work researching other options. Hopefully you'll find some better wheel options than the cheapo Ebay stuff.

Better brands: BBS, Rays or Enkei.

 

I'm still confused as to why the rep says you need coilovers to NOT rub. You're at stock height, lowering it would make it worse and lifting it is ridiculous. You will be fine with a rear fender roll. However, I wouldn't buy their wheels if they are that ignorant

 

those offsets and widths will fit fine with that tire. it may look like it will rub, but it will naturally camber in enough that it won't rub. the absolute max that would be needed to fit those is a slight roll. but probably won't need work honestly.

 

Search around for a quality used set.
Guy on here is selling his SSR Type F w/ tires for 1500 shipped...excellent deal

 

Sorry could't go back and change it, was using my phone and somehow autocorrected my spelling.
I don't believe him cuz I don't see why coilovers would stop them from rubbing, beyond that, why would they even rub in the first place, I saw posts on this forum with similar size rims and offsets have no rubbing problem even with stock fenders. As a newer owner I'm just double checking and expecting to learn from experienced owners. If I'm gonna spend a good thousand dollars on coilovers+camber kits at least I would wanna know why.
Yeah you got a nice point there, might have to think twice on buying these rims.

 

Since you're already this far into it why not have them test fit the back? Mine are 295/35/18 +15, and just barely scrubbed before roll. Obviously the fronts are stretched and fenders come pre rolled so you'll be fine there.
Your shop is trying to fleece your wallet, but you knew that. Find a Discount Tire and get it on the road. gl

 

How about a little semi-science in solving the FITMENT issue?

Start with the stock 18" size to know where you need to be (height expressed in inches because Jimmy Carter gave up pushing metric to us resistant-to-change Americans):

225 45% 18 25.97
245 45% 18 26.68

Why: You NEED to keep the tire height/rolling circumfrence and stock stagger F-to-R close to same to avoid speedo and/or VDC issues. 'Nuff said.

Also note that stock 17s are pretty close in overall height to the best/optimized 18" size (IMO but stated as such due to highest tire availability/choices) as are the alternate Nismo/GT-Track 2 sizes below.

Alternate 18/19" combination on Nismo or Track/GT-2
245 40% 18 25.72
265 35% 19 26.30

Now look at the available 19" tire sizes (if you must have 19s - but you can do the same thing for 18s)

Your stated choices are in RED because they're off by a significant amount - enough to throw off your speedo and mess with VDC if applicable. And besides looking off with such short tires.

235 35% 19 25.48 -0.49" deviation from stock
245 35% 19 25.75 FRONT - OPTIMIZED
245 40% 19 26.72
245 45% 19 27.68
255 35% 19 26.03 Alternate FRONT
255 40% 19 27.03
265 30% 19 25.26
265 35% 19 26.30
275 30% 19 25.50 -1.2" from stock!
275 35% 19 26.58 REAR - OPTIMIZED
275 40% 19 27.66
285 35% 19 26.85 REAR - Alternate
285 30% 19 25.73
295 30% 19 25.97
295 35% 19 27.13
305 30% 19 26.20

With tire sizing out of the way - where you should ALWAYS start; and fit wheels to the desired tires, not the other way around - you can look at wheels with an eye towards proper fitment of the tires and how they'll sit inside the wells.

Generally speaking, for Z33s - stock height or conservatively lowered - about the maximum you can fit with no rubbing is 9.5 wide Front, 10.5" wide rear with an offset no lower than about +15.

Note: Yes, there are exceptions and every car is different but this is, again, a general guideline. For reference, look at the "Unofficial Enkei wheels" thread for a good sample of fitment. Probably the most widely used combo is, as stated, but netted out here:

FRONT 18 x 9.5 +15 245/40-18
REAR 18 x 10.5 +15 275/40-18

OR

FRONT 19 x 9.5 +15 245/35-19
REAR 19x10.5 +15 275/35-19
Note: See "Edit 2", bottom, for notes on this setup on my Nismo.

If you go with very commonly found 8.5/9.5 F-R instead, you can go down on offset a bit, maybe down to around +10 before you start going for sidewall scraping/fender rolling required.

Final Note: If you find some wheels in the +20 to +30 (stock offset) range, don't rule them out. You can adjust track using spacers to give the proper "effective offset" of about 15mm if you need/want to push them out a tad for that "flush look". I don't really like using spacers but I do have a set on the REAR of one of my cars and they seem to NOT have messed up any geometry too much to affect steering input/reflex.

Hope this helps.

EDIT: Forgot to mention that you should learn how to use this tool: https://my350z.com/forum/tire_rim_calculator.php I don't use it for tire sizing, preferring Excel for that, but for "visualizing" (in a manner of speaking) offset changes, it's great.

EDIT 2: I should note that my own tire set-ups are based on "testing" in the hills and are somewhat conservative and are less "stanceable" than the forum members running 295, 305+ tread widths but work well - for my use - based on pyrometer readings. Car is heavy enough to get the tires up to Z-optimized 175 degF (for fast canyon/hill running @ initial cold pressure of 38F/36R.) I'd worry that anything larger won't heat up enough in my usage. Track usage may bring a 305 up to a nice toasty 185-200 but not where I run.

 

At stock height I'm almost positive those won't rub. Even if they do, the rep has no fcking clue what he's talking about saying that you'll need coilovers to NOT rub. Only thing I can possibly think of is that he's suggesting raising the car.

Either way, those tire sizes suck. The difference in front to rear width is too big and the rear should be a 35 series at that width, not a 30.

Assuming this is only street driven, I'd recommend 245/35/19 and 275/35/19 (for cost effectiveness and minimizing chance of rubbing) or 255/35/19 and 285/35/19 (for better performance). Your call.

 

Well +12 up front will be close but will work fine, it's a little short but that will keep it from rubbing. The rear is perfect but may require a slight roll, to combat a roll you can run a 265/35-19. This rear is a better match to the front and will have roughly the same amount of stretch as your desired front.

Odds are you will want a spacer for the rear and to eventually lower the car, neither are needed to run these wheels.
