Y33 wheel width & offset options?

[TrizzyDizzy]

Ok, so wheels are generally the first thing any Infiniti owner considers right after buying a car. Well i basically wanna know what my options are for buying a set of wheels. I generally sold on either 19s or possibly 20s. I would like the front and rear to be atleast 8" wide, but no more than 9.5" in the back. So what offset combinations can i run? Also, what would be an appropriate tire size to prevent any rubbing (i dont mind rolling the fenders).

Ive also noticed that clublexus has alot more of a variety of used wheels going through their marketplace, would i be able to use most of their sets if i decided to go with a used set?

Thanks for you time!

Falk has some pretty good knowledge on good fitment offsets for the Y33.

Keep in mind, there are people running huge wheels/low offsets with some camber. Most in the Q45 section of NICO are not fans of camber for fitment, so you won't find too many radical set ups.

Also, be prepared for the "load rating" lecture . With the Q being the first heavy car most members have had, they've never felt the need (or even knew about) to comply with the manufacturers minimum load rating. Higher load rating (from reputable tire comanies) will result in a "better" performing tire as impacted by sidewall flex.

Actually, it appears Falks are for sale, from his sig"Buy my wheels! Flawless condition, TSW 19x8 +20 Frt, 19x9.5 +20 Rr "IIRC, he had to roll the rear inner fneder lip to accomodate the rears.

I've been schooled on this from listening to fellow y33 owners like Falk and others and have picked up some things from my own experience also. If you plan on lowering your car, I say go with the 19s if you don't want to worry about rubbing. I think you should be able to get away with 19x9 with and offset of 20 to get that flush look. Also, you might consider running a staggered look. As for tires it depends on if you're a fan of the stretched look. If so, I think Falkens would be your best bet as most use them. And I've seen some mild to wild selections, but that part is up to you. Find the style of wheels you want then worry about the tires.

Exactly backasswards if you are interested in safety and performance.

Determine the tire required first based on load and speed requirements with an eye to size, then determine which wheels will fit and are strong enough without incurring a substantial weight penalty.

Many informative posts on this topic, starting with the tire sticky in Infiniti General.

What sense would it make if he decides on tires that meet the load ratings and speed ratings for his car but decides on some cheap @$$ wheels that aren't strong enough to support his car??? Aren't you the one who's always asking about weight and strength of wheels?

[Rex]

There's merit to your point, but under the guise of improved performance, tires are the one and only (hopefully) thing that comes in contact with the road. They will have as much if not more impact on starting, stoping and cornering than any other single component.

If you're going to go cheap, and wheels/tires is not a place to do it, don't go cheap on tires.

It's worth noting that the number of 19" tires that offer proper load and diameter are not as great, and oddly enough they're more $$ than an equal quality 20".

If it was me, I'd get some FX35/45 20" wheels (cheap, but OEM quality) and spend $$ on tires, but I really like that look.

[Falkdesigns]

Lexus offsets are too high for Y33, you'll need bolt on spacers to make wheels used on Lexus' work. I have exactly the sizes you're looking at: 19x8 & 19x9.5, both with +20 offset. Rears needed to have fenders rolled, fronts tuck in slightly (+10 would have been perfect in front). I have 245/35 F and 275/30 R tires. I'm selling the wheels alone, looking for $1000.oo obo.

[cullenj76]

Totally agree with Kevin(Falk). Any lexus wheel will have WAY too high of an offset. Falk's wheels would fit your car perfect with a 10-15mm spacer up front.

Just for reference, the wheels I ordered are 19x9" +15 and 19x10" +22 and should fit perfectly flush.

[TrizzyDizzy]

I appreciate the help everyone.

Now i do plan to lower the car, maybe just 1.5-2". I also plan on running staggered. And now im leaning much more towards the 19s.

What is the proper load rating for the wheels i ahve to worry about? Also, what would be a good range of offsets to fall under for a 19x8.5 and a 19x9.5.

Also, how bad are spacers to use for your car, ive heard they arent as good as none... but would saving $500-1000 on wheels you like, be worth a wider spacer?

I appreciate the offer Kevin, but i prefer a wheel with more face, similar to the Work Euroline DH wheels.

[Falkdesigns]

As for offsets in those sizes, I already posted mine above, but a perfect offset in what you're looking for would be +10 ~ +15 front and +20 rear.

The Tein S-Tech springs I sell drop the front 2" and rear 1.75" so if you want some, you should send a deposit as I usually sell out before they even arrive.

[TrizzyDizzy]

I appreciate it man. When do you usually get a shipment of springs in? I honestly might order a set within the next week or so.

[cullenj76]

Exactly how "flush" of a look are you going for with your wheels?

Must read the whole post to comprehend it. Maybe invest in a little thought and reflection also.

Stock Lexus wheels have bore centers that are too small.

[TrizzyDizzy]

As in flush... i mean with a slight bit of negative camber (basically what lowering springs would give me), i want the lip of the wheel to run down at an angle. Have the tire tucked underneath it (stretched).

I dont want stock lexus wheels, i was talkin about aftermarket wheels that were originally used (and sized) for lexus/toyota cars. But i figure id need atleast a 30mm spacer to mount on anything i see over at clublexus.com.

I understand that you were talking about aftermarket wheels that were on a Lexus, but could fit your car. The problem with that is you are not going to find the right fitment and you will also lose a lot of lip.

From what your saying I'd go with a 19 x 8.5 + 7~10 up front and a 19 x 9.5 +15. That will set you flush with the fenders and a very slight bit of camber. Tires are up to you. It really depends on how stretched you want. I'd recommend a 235/35 up front and a 265/30 out back, but you could as conservative as a 245/35 in front and 275/30 out back or as stretched as a 215/35 in front and 235/35 in back. I do not personally recommend going with that much of a stretch if this is your daily driver, some will agree with me and some won't, but that is just my advice. I'd say a 235/35 and a 265/30 will give you a conservative enough stretch to keep you happy when you look at the car AND when you are driving it.

[Falkdesigns]

Yeah, sometimes Brian (Maxnix) posts things like this when he's really got nothing to add. I think everyone but him knew you weren't talking about stock Lexus wheels.

Anyhow, I'd run 235 fronts on my 8' front rims if only someone made a 94 load rated 235/35-19 wheel. I like the way the 275 fits my rear 9.5" rim, but the front is a little too straight up for me. I'm not a fan of extreme stretch, but I do like a mild stretch. If I could, I'd have 19x9.5 front and 19x10.5 rears with 245 front and 275, to me that would be tit's.

[TrizzyDizzy]

yea, this whole stretched tire thing is entirely new to me. I was big into Subaru performance... and we were generally trying to fit the widest tire on the smallest (race-legal) width wheel possible, lol. Then trying to roll the fenders to compensate for a 255 on a 17x8.

Ill follow that advice of yours cullen and falk. Im not much of an extremist anymore, and the car is my daily driver, so your advice is as good as gold to me. thanks

Yeah I wanted 9.5 and 10.5 but AME only makes up to a 10" width Sounds like your "EXE" tastes are exactly like mine; a super clean look while still being realistic.

[kg03]

I have the opportunity to get a set of OEM 19's off of a G35 with a 19 x 8.0" in front and 19 x 8.5" in back and The tires are Bridgestone Potenza RE050A and measure 225/40/19 up front and 245/40/19 in back. Would these fit according to the standards and best practices mentioned above with respect to tire selection for a y33. I don't plan on lowering and I don't like the "camber" look. I don't want to have the fenders rolled either.

Any suggestions?

thanx in advance.

IIRC, they'll be fine, may be a little sunken for some tastes.

Check the tire load ratings, as I think they're below the manufacturers minimum for the Q, both Y33 & G50.

[kg03]

When u say "sunken" I take it you mean sunken from the fender (not flush). If so, how far are we talking about. I would like them to be as close to even as possible without ubbing scraping of the tire or any other modification to the fenders.

[Falkdesigns]

If you can find the offsets for the wheels we can let you know easily. Stock Q (Y33) wheels are about +40, which is really sunken in. And you'll definitely need to replace at least two of the tires (load rating on 225 is way under the min. 94 needed), the 245's on the rears are what you'll need for the front, you'll need 255, 265 or 275 for the rear.

Kevin, the wheels he referencing are 8" & 8.5" with 30 & 33, or something very close to that.

[cullenj76]

Y33 OEM offsets:(depending on which wheels you have)16 x 7 +40 (front and rear)17 x 7.5 +30 (front and rear)

Rays G35 offsets:19 x 8 +30 (front)19 x 8.5 +33 (rear)

Given those measurements, if you mounted the G35 wheels with no spacer on the Q it would give the following results:

If you already have the 17 x 7.5 +30 wheels:Front: extend an extra 6mm toward the fenderRear: extend an extra 10mm toward the fender

If you already have the 16 x 7 +40 wheels:Front: extend an extra 23mm toward the fenderRear: extend an extra 26mm toward the fender

Rear: Now, that will leave you about 26mm more sunken in than Falks car(see his sig pic) in the rear and about 32mm from actually being flush with the fender in the rear.

Front: That will leave you about 30-35 mm from being flush with the front fender and about 10mm more sunken in that Falks fronts (which are already to sunken in to begin with )

That being said, you could run a 30mm hub-centric spacer in the front and a 25mm spacer in the rear with the wheels. That will get you as close as possible without requiring any fender work.

[TrizzyDizzy]

wow, i honestly thing you guys explain the whole offset/width/tire thing much better than when i had to learn it for subarus, years ago, lol.

[kg03]

would the hub centric spacers affect the structural integrity of the suspension and hubs?

Not at all, so long it a nice quality hub-centric spacer like H&R.

Our sponsor, http://www.tirerack.com, sells H&R spacers.

Exactly.

In a perfect world spacers wouldn't be needed, but if they are, please PLEASE do nto use the $24.95 a set ebay ones .

Quality H&R or such should run you >$100 a pr.

[maxnix]

Well, it is an inert piece mechanically connected to neither the wheel nor the hub, so the bolts have more stress on them due to the increased leverage. And there is some added unsprung mass.

Personally, you are much better off getting the correct wheel.

[Falkdesigns]

Actually, it essentially becomes part of the hub as it is bolted to the stock studs, which are part of the hub. As I've said before, 8000hp Top Fuel dragsters can use them with no problem, and somehow certain folks on here think a car on the street puts more stress than that does. Forget that, they've been in use on the street and race track for decades, with no problems. This is not some new invention, it's tried, true and OLD technology that WORKS.

But yes, if you can find the wheels you want in the offset you want, that is the best solution.
