Saw these wheels, polished Saleen 18x10 6.38 backspacing and 22 mm offset. Shoudn't this move the wheel over an inch away from the rear shock and eliminate the need for spacers?

It will likely stick out slightly with 305 -35's , but that should not be an issue.

they will actually move out 53mm (a tad over 2 inches) that kinda seems like alot...

every inch counts! lol but yeah 2 inches also has to be considered for suspention travel and if fender is impeading the tires suspention travel range.

2 " would be a lot.
What am I missing here? The stock backspace and offset is about 7.5" and 50mm. I only see it moving 28 mm, the tire is the same width that people are running on the widened wheels.

What is the backspacing on a widened wheel? 9"? That may be what I am missing. I assumed the widened wheels were backspaced the same.

well here I'll try to explain. The widened wheel is no longer 50mm offset seeing as offset is meassured from the wheel center to where the hub connects.

whith those wheels you have there the hub connects at 22mm from the center (5") 22 mm is a little less than an inch (~25mm) to that leaves an outward space of a little over 4 inches.

now stock is 50mm (2 inches) from a center of 4 inches, hub to lip is then 2 inches so as you see the new wheels extend out 4 inches from the hub, where the old ones were 2.

with widened wheels the outward move is still only 2 inches because the hub hasn't moved, the wheel as just been extended inward, while the offset has now canged because the center is now 4.75 instead of 4 inches. But ya you get it now ya?

Juno, hey I have those exact rims on my wifes 03 Grand Marquis, only in gunmeatal. They actually make the car look more aggressive because its in a wider stance. Car handles well. She has hers on 35 series tires. Heres a pic, but no comments on the gap, eibachs are on the way.

OK, maybe it's just me, but the math doesn't seem to work with these numbers.
A 10" wide wheel, with 6.38" backspacing, should have a 35mm offset, no?
Or put another way, a 10" wide wheel with 22mm offset would have 5.87" backspace.

Or am I just math-challenged?

In my opinion the rear wheel well needs to be filled out to look good. These are my widened factory wheels, with the Nitto 305/45/18's. Sent them to Lidio for the widening service. IIRC, Trilogy makes their own custom wheel to fit the Nitto? I could be wrong. This is my MM...

It just doesn't look any more mean than that. No issues with spacers, no issues with the wheels sticking too far out. No rubbing. No issues at all. I love the way they look. People always ask me to roll down my window to ask me about them. Nice and easy, no hassle. Thats the way I like it.

Couldn't agree more. All the MMs I've seen with the widened factory wheels just look so... right.

You can take these wheels on and off all you like, and won't have any of your "sticking out too far" issues, while maintaining your OEM look while at the track. Unless you like the look of missmatched wheels. You can use these specifially for the track. There's nothing quite like a custom made part for our unique vehicle.

You're forgetting that a 10" rim is 10" wide on the bead, but is actually 11" wide; rim edge to rim edge.
11" centerline = 5.5" = 139.7mm
6.38" backspacing = 162mm
162mm - 139.7mm = 22.3mm offset

BTW: OEM 8" rims are +50mm offset = 6.5" backspacing...Widened rims (1-1/2" to the inside) are 8" backspacing = 82.6mm offset!

There is no question those are nice, but I can't put 305 -35 nitto's on them.

The 35's are a little shorter, right? Any reason for the 35's over the 45's? Just curious. Before I did this mod, I was considering suspension mods, cutting my springs, or replacing them for aftermarket ones etc. Well...once I got the 305/45's on, I liked the new rake of my car so much, I decided to leave suspension alone completely.

If you're talking dragstrip, then I'd say it's a good thing, for two reasons.

1, the smaller overall diameter will effectively lower the final rear ratio, and, 2, you're putting more rubber on the road, for better traction off the line.

I hope you're not offended, but I couldn't help noticing that she backed into the bird bath, although the poor Yucca plant seems none the worse for the event.

Never mind that backing into things is an common occurrence around these parts.;)

Yes, 2.4" shorter and gives me a 4.10 type ratio for the track.
That is the whole purpose of the thread, to talk about 10" Drag wheels that fit.

The birdbath was being repaired at that time. What are you doing, dissing my yard??? I live on 3 acres in a "back country" region of Florida. Mostly all farmland and horses. Also keep in mind that the picture was taken shortly after a category 3 hurricane passed through, so my yard wasnt up to par at the time.

Ill post more pics soon. Juno, you can come on by anytime to see the car in person.

I'm confused...

I believed that offset was the measurement from the mounting hub (where it contacts the axle), to the outside (front) of the wheel, and backspace was the measurement from the same mounting hub to the inside (back) of the wheel.

If I am still correct, wider MM wheels from Lidio still have a 50mm offset, which predicts the clearance available between the outside of the wheel/tire assembly, and the inside of the fender lip. Lidio's widened wheel does not relocate the mounting pad, the mod justs adds more width to the back of the wheel. Expanding the 8" wide wheel to 9.5" does change backspace.

I've experimented with a few different sizes, and IMHO, you can use any offset between 50mm and 35mm, and still clear the rear wheel well lip. Anything less that 35mm, and the tires will rub the wheel well, unless you select a shorter tire. You could prolly fiit an 18X10 wheel in the back, if it has less than a 50mm offset. Can't say the same for the front, 'cause I have 1 coil cut from my springs. I'm guessing the max fit would be 18X9, 40mm offset.

I'm also confused about the Nitto tire sizes mentioned here. I know the Nitto drag radial is 305/45-18, I didn't know they also offered another 305/? size. It that a racing tire also? Or, a road driving tire?

Just asking for some clarity, carry on gents.

For your (and everyone elses) information / reference ... BTW - Offset is the measurement from the middle of the rim to the mounting surface.

It's a drag Radial, but the lower profile requires a 10" rim. 305-35-18 is 26.4 " tall, It will add about two gear steps to your car over the stock or 305-45's. 3.55 = 3.90, 4.10 = 4.56. And it has a little more contact patch than the 305- 45's.
A nice option for those who chose so. I don't intend to use these anywhere but the track.

The other wheel option is an 18x10 FR500 wheel with 50mm offset and 7.5" backspace in chrome.

SergntMac

01-31-2006, 03:38 PM

This is why I get confused...

Here's a link to three pics of my Marauder from the side.

http://www.mercurymarauder.net/showcase/showimage.php?i=1296&c=3&userid=392

What's sticking out? Can anyone here look at these pics and tell me if I have stock 18X8, or, Lidio's 18X9.5 wheels on the back? Can you see any difference from these pics?

Anyone?

No, you cannot.

Thanks, Joe, and I apologize for my momentary misunderstanding of offset as it has been discussed in this thread. Seemed to go against what I learned at this site...

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

Because the same diagram you posted explaining offset is also used to explain backspace at this site...

http://customwheelsmarket.com/higperwheel1.html

And I thought they were different measurments...Goofy me, eh? I must have homogenized the two into one train of thought, because my Marauder looks like this...

http://www.mercurymarauder.net/showcase/showimage.php?i=1296&c=3&userid=392

Let me state my point another way?

I have a set of 18X8 OEM wheels, and a set of Lidio 18X9.5 wheels. When I mount either set on my MM, the outside edges of my tires, where they meet the pavement and where they meet my fender lips, do not change.

The added tire width is all on the inside, therefore, when you have Lidio's wider wheels, the outside of the wheel/tire does not change, the added playground is all inside, which is all I was trying to explain.

Offset vs. backspace...Whatever.

When y'all go wheel and tire shopping, bring a calculator?

I'm having a hard time understanding this one.

I have 305/45's, and 4.10's. Does this mean my overall rear gearing = 4.56 now?

I'm not arguing...just probably missing the point, or just not getting it. Can someone help me out on this?

Also, won't the width, or contact patch be the same on both? They are both 305's...I thought that was width.

Mac, thanks for settling the "backspace v.s. offset" for me.

BTW what's that big building to the left rear of the car? It looks to me like some sort of concrete structure, and Barb says it's a canvas/vinyl material stretched over metal supports; but whatever, it must be made out of tough stuff to withstand a category 3 hurricane.

How about some photos?

Mat, these are 35 series tires, so they are 2.4" shorter than the 305 45's.

try http://www.svtoa-atlanta.org/cgi-bin/trans.cgi It will let you compare gears and you can change tire size also to see how it affects RPMs. The 4r70w is at the top of the tranny selection list.

259 each.

With the correct wheels someone can drop their ratio a couple of notches for the track and still have whatever gear they prefer for the street.

I know, I was being sarcastic. The structure behind the car is pure steel and a concrete foundation. It holds all the Yard maintainance stuff and a tractor. Our grounds keeper stays in a living quarters inside. The thing is a fortress. I went to take an all around video today on my way to work and ny canera batteries went dead.

Yes they are Mike. I love the way they look. I'm so used to it now, that when I see a stock rear tire on another MM, they look skinny and weird to me. I get plenty of compliments from people on the road, and at car shows etc. They can't believe that a huge 4 door car like ours has drag radials that look as good as these do. I must say...that I have seen some of the BFG's on some MM's as well, and the BFG's look awesome also.

I missed that question.
According to the Nitto site, the 35's are about .35" wider than the 45's likely due to the wider wheel . If you mounted both on the same size wheel they should be very close.
