How wide (tires) can I go on the BMW 330 ZHP???

[ejhahn20]

Im looking to possibly move to a more aggressive wheel set up... I know zhp wheels are 8 wide in the front and 8.5 in the rear. I would like to do 8.5's in the front and 9.5's in the rear. Will this be to wide or is this doable? Help would be greatly appreciated.

Depends on how low your car is.

[ejhahn20]

my car is stock height as of now but lowering springs or possibly coils would come along with a new wheel setup.

[mimalmo]

Depends on how low your car is.

...and offsets and tires and camber. There's plenty of variables involved.


Here's my previous setup with 9.5" rears and 8.5" fronts.

Damn that looks good. How is that different from your current setup?

[mimalmo]

I sold that setup a couple months ago. Currently running OEM ZHP wheels with Blizzaks for the snow (though it hasn't seen any snow yet). Undecided for next year. Sadly, it may come down to a budget thing. While I'd love to splurge and get some baller wheels, I might not be able to with the way the economy is (still) going.

[pyreguy]

When I was buying my car I was already planning on getting a set of gunmetal V710's. But after having it and looking at the 135M's everyday, I don't think I would be happy going with anything else. Still thinking of powdercoating them a little darker, but I flip flop on that daily. I really like the stock wheels on this car. I don't believe I have ever felt that way about any other car I have ever owned.

[mimalmo]

I just wish they were lighter.

[ejhahn20]

Thats funny you say that Lance... I've though many time of powder coating my wheels a darker gray. I think it would look very good!

[danewilson77]

This is what matters...

http://www.tirerack.com/wheels/tech/techpage.jsp?techid=101

And also ride height.....

[ejhahn20]

So what offset would I need run to wheels those widths?

[danewilson77]

With stock ride height?

[danewilson77]

I. I frequently will use this to aide in deteriming offset....

II. Here is also a wheel offset calculator.....

http://www.1010tires.com/WheelOffsetCalculator.asp

III. Now that we know the above......say I am going to go from the rim I have now.....to a stock style 135. Lets just talk about the rears.

CURRENT: Enkei's are 18X8 with an ET +42 offset.

FUTURE: Style 135's are 18X8.5 (rear) with a ET +50 offset...

IV. Plugging the above values into the calculator in II, above.....it yields the following information:

Inner Clearance: >>>>>>> 14mm's less than my Enkei's. the inside of the wheel to the strut housing.

Outer Position: >>>>>>>>Retract by 2mm's (position of the outside edge of the wheel)

***So....what the above numbers are telling me (in IV, above) are.

I may need spacers, if I do not currently have 14mm's from the edge of the wheel to my strut brace.

Additionally...my tire will still be recessed 2mm's inside of my wheel well. Not very much clearance....and if I am lowered at all....I will probably end up rubbing....which can somewhat be taken care of through the use of a stretched tire, or by adjusting my camber.

There is by "the book" and then there is reality....


I am running V713s at 19x9.5 et33 all around on an e46 chassis with 235/35/19s and rolled fenders. My car is also very low.

[Marcus-SanDiego]

Damn, Casey. That shiznit is slammed!

[danewilson77]

Not slammed but lower than stock. Casey, what are you lowered on?

[C Withers Media]

Not slammed but lower than stock. Casey, what are you lowered on?

2 and half inches lower than stock, lol.

60 millimeters = 2.36220472 inches

[danewilson77]

Copy. Really looks good casey. Did they use the typical tool to roll the fenders?

[pyreguy]

Okay, that picture with the focus up top for the back and down below for the front was both brilliant and well-executed. And I love 'em low like that! Beautiful car!

[ejhahn20]

Thanks that definitely helps clear up my confusion.

What changed, you said previous set up? Why did you change? What dia are those? 19 offset?

[mimalmo]

I sold those wheels & tires a couple months ago. Currently on the OEM ZHP wheels. It was just time for a change and I didn't feel like storing them for the winter.

The full specs were:

VMR V710 in Hypersilver

19x8.5 ET35 front with a 235/35/19 tire
19x9.5 ET45 rear with a 255/30/19 tire
Tires were Dunlop SP Sport Maxx

I'm still on the same suspension setup - KW V2 coilovers

Fenders are lightly rolled.

[Mtnman]

your setup in your pic is sic nasty. we have the same color, but u have a better setup. i have car envy.

[jjcools]

Did you roll your fenders? That set up looks perfect for me. I would like to find something lighter, 22lbs for cheap 19s isn't too bad.
Maybe these in gunmetal

Thanks. Just add some coilovers and some spacers to your stock setup and you too can get a similar look.

Good point. I'll edit my post above. Fenders were lightly rolled to accommodate my ride height/offset/width.

[jjcools]

Thanks Eli, good luck with the new wheels.

[Bimmerlifestyle]

next wheels im going with 10.5 or 11:)

[danewilson77]

I dont believe you...

+1... I once tried on a set of 17x9 +40 wearing 255/40/17 Toyo RA1s and didn't get 10 feet before the rubbing started on the right rear corner.

I run 18x8.5 +42 offset with 255/35/18 tires and some tires rub a little, others do not. My issue is up inside the rear fender well, not on the lip. Under full compression I'll get minor rubbing... like in an uphill corner on the throttle, or large dips. Casey's stretched tire is what allows him to run that setup for the same reason.

Man, I sure like the look of those V710's! I wish I had the coin for forged BBS wheels of similar design. I've warmed up to the SSR Comp-Hs, but they were not an immediate "oooh, ahhh" reaction from me when I bought them. I went with them cuz they were a great deal (used with new PS2s), light, easy to clean, and square. I miss the look of the 135s too, but not the cleaning hassle. Since getting my car new products have come out to make wheel cleaning easy though.

[Marcus-SanDiego]

Agree with Jeff.

There will be a ton of work in the wheel well to make a 10.5 or 11 work.

Jeff, as you'll recall (back in the day), many of us had to put M5 wheel liners on our 5-series vehicles to accommodate the wider rims we were putting on our cars. Beyond a 10-inch wheel, there were actual modifications that had to be done in the wheel well, too.

On my 5 series I had to roll the fender, pull the fender out, and swap wheel liners. True, I was running an aggressive offset, but that's a lot of work just to make a 10-inch width work.

I can only imagine the kind of work necessary to make a 10.5- or 11-inch width work.

[danewilson77]

Fortunately...his fenders are rolled AND pulled. My guess is that he'll be pulling them a bit more.....

[Marcus-SanDiego]

Yep. There is going to be some more work, too. I'm thinking the biggest worry is the rubbing that will occur in the interior part of the wheel well, toward the center of the car.

[Bimmerlifestyle]

the sky is the limit

[Marcus-SanDiego]

Be careful, Ernie.

He'll just add spacers to prevent that.

I too like the look of the V710's. A set of gunmetal ones would be sick on my car. I like that you can even get them with roundels.

The problem is that I have seen a few sets of them (though not in gunmetal) around town. My 135's are much more unique it seems... Thinking I will just make these gunmetal...

[jvr826]

Jeff, as you'll recall (back in the day), many of us had to put M5 wheel liners on our 5-series vehicles to accommodate the wider rims we were putting on our cars.

I can tell you on the E46 coupe there is no such luck. I had my suspension shop "work" the inside of my rear fenders a little and all they could get was at most an additional 1/4" of clearance, which didn't really help me. It's double-wall construction at that point with very little space between the inner and outer (visible side) of the rear fender.

I may be able to reduce the drop, increase the camber, but the problem for me is so minor that it isn't worth futzing up the handling I've worked so hard to dial in. With fat new tires on (Dunlop Star Spec or similar) it will rub for a little while until the fender modifies the tire. :-) Free!!

With the PS2 and the RE11, no rubbing at all. Their shoulders are more rounded. I had BFG KDW2's on there once, huge meats, lots of rubbing.

What's good about the 135's, and something I miss, is that they look like 19's because of how they're shaped.

[pyreguy]

^ I'm glad I'm not the only one that thought they looked bigger than 18". Some weird optical illusion..

[Marcus-SanDiego]

135s for the win. From my car:

[pyreguy]

Yeah, I will be hard pressed to ever change out these wheels since they are unique to this package.
