Any pictures of Stepsides with Coys C5?

[CC69Rat]

I love the look of Keith's truck but I'm thinking 20's all the way around for mine. Does anyone have any pics of a stepper with Coys? I see a lot of fleetsides but I'm curious about tire sizes and backspacing on a stepper.

Keith's (Stella Mae truck) has a 22x9 on the rear with 5" BS. 265/40/22 with an early rear end. He said he had to trim a little off the outer edge of the rear fenders to make it work. That tire is 30.39in dia and 10.7" section width. So he is 4+ and 5- ..

I am looking at a 20x8.5 with 5.25" BS for the rear. 255/50/20. I like a little more tire. It will be 30.1in dia and 10.5 or so section width. that puts me at 3.25+ and 5.25- Worst case I can slip one of those disc type spacers behind it to make it perfect. Ideally I think 3.5+ and 5- would be right on it.

20x7 on the front. 245/45/20. My truck is going to be pretty low. That tire is 28.7in dia and 9.4" section width. I have dropped spindles and the 73+ swap. I think my track width might be a little wider but I'm not sure how much.

Running a 7 on the front I'll have .5 difference in the positive offset, so I think it will still have the 'big' look and I can run plenty of tire.

255/50 and 245/45 on this setup would make the sidewalls roll out almost exactly the same. Within .1". No chance of rubbing from lock to lock (?)

Your thoughts? Do you think it would work? I think I'm going to order them tomorrow.

My opinion.
Your tires are too big.
A 245/40 or 255/40 up front is the max height for a LOW truck,... unless you pull your inner fenders.
Those 255/50's on the back will also be huge!
I have a '70 stepside.
Those rear fenders are tiny.
Trying to stuff any size wheel under the fenders is very difficult,... unless you plan on mini-tubbing it.

Plus your backspace numbers are off.
a 20x8.5 wheels actually measure about 9.5" wide.
(the 8.5" width is taken fron the "bead surface" of the rim)
The backspace will be correct,... but you need to add 1" to the front side,... or your plus numbers.
(5.25- and 4.25+,... in the way you put it)

[CC69Rat]

So a wheel with 5.25 BS is measured from the mounting flange to the outer edge of the wheel?

I have my step fenders off, and laid flat on the ground. In this case the garage floor but you get the idea. If the floor was simulating the bed sides I have 11.25" to the edge of the wheel lip on the fender. Understanding I will need at least an inch of clearance from the edge of the tire to the bedside.

I'm concerned the 255/50 will be too big too. So 40 on the front. Got it.

8.5" bead-to-bead. (Inside where the tire meets the wheel). But 5.25 is measured to the outer edge of the wheel.

What are your plans for Ginger's tires and wheels?

This was kinda why I was asking for pics. You're right it's tough to stuff a stepside. I think it will look good.

Stella Mae has a 265/40/22. That tire is about 30.4, taller than what I was looking at..

Lolife99 - it just hit me man. You're exactly right. Overall width, etc. You are the man! Thanks. You probably just saved me on a costly mistake.

I like 40 series tires on 20's.
35's look too small to me.
Plus the rear sidewall has to be in proportional with the front side wall.

Tucking a 10" rim is different than just bolting on a set of 10's.
I think Stella's 22x9 is the max width wheel without mini-tubbing the bed.
The height is tall because they are 22's with a 40 series sidewall.
Anything shorter would look funny compared to the sidewall of the front 20" tires, which are also a 40 series.

[lolife99]

Here's a backspace chart.

[lolife99]

Since Ginger is going to lay frame,... the tire will have to be all the way up in the fender.
This limits the width of tire/wheel I can run due to the outside curve of the step fenders.
I think a 8.5" or 9" rim is the widest in a stock un-modified rear stepside fender.

[lolife99]

15x8 ralley wheel.
(4" backspace)
Narrower 67-69 rearend.
29" tall tire.

I'll be running 20's.
These are just for mock-up.
The fenders are setting on the tires.

Stepside bed?

[screaminchevypickup]

Yes a step side I had a 67 stepper that was lowered 7 in the back with a 20x10 coy c5 with no mods and never rubbed

This is a truck off of porterbuilts website.

Front:
20x8.5 with 5.25bs 255/40/20
Rear
22x9 with 5.00 bs 265/40/22

[Shane]

I believe that truck above is also running the narrower 67-69 rear-end housing

[CC69Rat]

With the 73+ K member swap on my truck and McGaughys HD 2.5 front drop spindle and rotor kit - Do you think I might have added a little to the track width? The factory springs were also cut one turn by the PO. .. and the iron headed big block of course

I'm tempted to just get the same setup Keith has on the Stella truck. I need to do a notch anyway. My axle tube is pretty close now and I have at least 5 maybe 6" drop springs in it. I'll get some pictures of it this weekend.

I'm afraid my exhaust is going to be a big problem too .. Ex. If I go low enough to run the Stella Mae setup and make it look right I really need to go low enough for bags, causing other potential problems. I want to be able to drive it and not bottom out or bend the crap out of a wheel if I hit a pothole or something. That's why I was looking at the 20x8.5 for the rear.

Thank you for this, GREAT information.

I also have a stepside ('68), and I'm trying to figure out the wheels and tires. I will have a 6" static drop in the rear, will be running a Watt's link to minimize any side-to-side movement during travel, and decided not to c-notch. I want to run a 10" wheel, and a 295/40/20 tire, but is that even possible?

From the picture you posted, it looks like I would need a 6" BS on a 10" wheel with the narrow rear-end to make it work (IF it's even possible), correct? If I'm looking at it right, that would put the outside of the wheel about 5" from the mounting surface, just like your 8" mock-up wheels, and should just clear the inside edge of the fender lip. With the wheel well width of 11.25", it will be very close on the inside as well.

I only ask because it seems like most of you guys want to go lower than I do, so I'm wondering if you think it will work with a static 6" drop in the rear?

[CC69Rat]

Portmod7 - I was really undecided about wheels when I posted this, and I went to Shades of the Past in Pigeon Forge TN back in the summer. Billet Specialties was there. They are now offering a wheel with a Billet hoop, but cast center. It gives you the options for custom offset (if that's really what you want to get into) but they are a little cheaper with the cast center. I was looking for the gray face wheels with more of a vintage look. Considering Coys C5 at the time but I personally just wanted something different. Something I hadn't seen before.

I bought a PErcy's Wheelrite from Summit. It is a really cool tool that will allow you to measure your truck (all trucks are slightly different) and get a true look at what wheel diameter you want, tire size, etc. You can really get close with it. Everyone has their own look and opinion they want .. but I'm kinda with you. I want to go as low as I can without bagging it or making the ride really bad.

I am running 2.5 McGaughys dropped spindles in the front and ~2" in the springs + my extra weight if the engine. In the rear I have 6" dropped springs. I have the earlier Rear end housing. If yours is the later rear, it is 57" plate to plate. The early one is 55.5" so you'll want to adjust accordingly.

My truck measured to:

Rear - (I'm running 20's, not sure what you're thinking .. 22" ?) To be 100% perfect 4 5/8 backspacing put it really comfortable. (I may go lower soon ) To squeeze everything I could out of the width. I ordered 4.75" backspacing.

I have 255/45/20's on the rear. Nitto 420s tires. I don't recall for sure, but I think the tire is 30.4" tall. You might check me on this.

I have a picture of it below. Remember, my truck is completely stripped down, no bumper, no wood in the bed, no gas in it.

Question - Are you ok with cutting your step fenders to get bigger tires to fit? Rolling the wheel lips? Trimming a little here and there? Me, .. No. I didn't want to risk any structural integrity of the fender or cause it to flop around or worse (my luck) mess up some rust free fenders I looked all over the place for)

I am really happy with mine. 255/45/20, 20x8.5" wheel, 4.75" BS.

In the front I have 255/40/20, 20x8.5" wheel, 5.5" BS. My truck has the 73+ swap, and HD rotors so I gained a little track width.

** If you're considering Coys. They have a 20x8.5 wheel with 4.75" BS for the rear, and a 20x8.5 with 5.25" BS for the front. This would be the PERFECT setup for a stepper. This will put you in the 255/45 or 265/50 absolute MAX, just My opinion

They also offer a 22x9" wheel with 5" BS. IF you're ok with a shorter sidewall (?) a 265/40/22 is freakin sweet, and Raul has 285/35/22 on his stepper if I'm not mistaken.

If you have a 6" static drop - In conclusion, 20x8.5 and 4.75" BS is the ticket. Just my opinion. If you're ok with cutting your fenders you may have another 3/4 or 1" wider you can go towards the outside. But, I wouldn't go more than 5" backspacing. Mine, you can put your finger between the widest point of the tire and the bedside. It's pretty close. On the outer edge it clears, but just barely. I could bag the truck and the tires wouldn't rub completely aired out. But, not more than 1/4" clearance .. if that.

Some guys run wider wheels but personally I like a little more tire. It just all depends on what you want. I'd rather have a tire that's wider than the wheel vs. the oposite. Just my taste.

Hope this helps.
Sorry for the novel .. just trying to explain. Maybe this will help my stepper friends. Let me know if you have questions.

[Portmod7]

Thank you for the reply!

I really like your project. I was looking at the build thread and had seen what you had decided on for wheels, they look great!

I am torn between the Coys C-5's and Eagle 225's. I'd like to get some BS wheels, or something similar, but the price of the Coys and Eagles has me won over. I'm not doing any body work on my truck, it's definitely just a driver as far as looks go, so I don't want to break the bank on a really sweet set of wheels. I was REALLY set on running a 10" wheel/tire setup in the back, you see them on the fleetsides all the time, so I hadn't really thought twice about it. Now it really sounds like I'm just not going to be able to do it with the bed in stock form. I wouldn't mind rolling my fenders a bit, but I definitely don't want them flopping around like you said.

You gave me a really good idea of what I'll need to do in the rear, thank you! I'm not sure at all what I'll be doing up front. I've got the Hotchkis TVS system with 73+ stock-height spindles and rotors. So I'm really not sure if I can work off of what most people on here are running, I haven't come across anyone who's got that setup on 20's yet. I'm not sure if the control arms change the track width, or the spindles I have, or the hubs, etc.

Thanks again for your help, I appreciate it! And nice work on your build, keep it up! I ought to put mine on here, but I'm not very good at getting pictures. I'll definitely put a before and after post up when I'm done though!

Looking at my earlier post, I feel a little dumb. I asked about running a 295 tire after you said the "wheel well" on a stepside was 11.25". So yeah, no way on the 295's, and I don't like the look of the wheel being wider than the tire either. Sounds like it's 8.5" wheels for me!

Awesome information for the stepside crew - CC69Rat

You clearly did you're research and referenced some of the top stepsides (StellaMae, Ginger, etc..)

Already had subscribed to you're build thread

Keep up the good work and great info

I'll be using it when it comes to ordering and measure time for my wheels.

Chaulk up another bookmark

[RdoubleU]

CC69Rat and lollife99 I need some of your expertise in the stepside area

Gonna pull a CC69Rat and may this a long one

I have a 68 stepside with 4.5/6 drop
Front:

• CPP 2.5" spindles
• Porterbuilt Arms 1" forward
• 2" Drop Springs

Rear:

• 2" Blocks
• 4" Springs

First Issue: I measured my axle to double check and I'm getting some conflicting measurements. Plate to plate is coming up as 57" (70-72 rearend) but my old 6 lug axle shafts measure 30.5" (65-69 rearend) and I also rebuilt the axle earlier this year and used Moser conversion axles part # Part #: A30-65GMT5 which also measure 30.5"...and im pretty sure this truck has never been touched before but just paranoid about the 57" measurement.

What plates are you measuring from? Im measuring from the mounting flange because i currently do not have any brake brackets installed..Trying to triple check measurements

Coy fitment: Reading the above and a few other threads and if I do indeed have the early rearend. It looks like I only have one option for 20" coys that will fit correct?
-20x8.5 wheel with 4.75" BS for the rear
-20x8.5 with 5.25" BS for the front

Coys doesn't offer any other 8.5" BS options so its kinda that or nothing or am i wrong?

I have the 1 1/4" rotors and have read off and on about fitment issues:

• Do I have to grind on the rotor any to get the wheel to bolt up? As in the center bore of the wheel wont be big enough?
• I do understand I will need a spacer to clear the dust cap
• But are the fitment issues people keep talking about just one of the above or both?

thoughts?

[big_al_71]

here are a few picts of a stepper with coys and no mods to the bed and there is no rubbing. The truck has 20's and 22's, there is a build thread for this truck and the members name is Raull maybe he can also give you some advice as to what he ordered..

[CC69Rat]

Pull a CC69Rat huh? .. . yes, Im a talker.

Who is this Raull guy again? You feelin better buddy?

Thanks Big Al...and I've been following yours and Raulls progress
Twin turbo 5.3 stepper is going to be beast
Also the shots of Raulls Coy's is what sold me on them

Haha I can't complain, I got some of my best info from the talking

I even measured my Wheel well and it matches the 11.25" you mentioned

Any idea on where I'm missing the plate to plate measurement on? With the stuff I said Im pretty sure its a early housing but im seeing 57" come up from mounting flange to mounting flange

[RdoubleU]

Here's some info I pulled together from above and others rides:

Again based on these specs , and wanting to go with 20's on a stepper it only looks like one option is possible with Coy's

I dont know what Raull ran for BS up front but I bet its 5.25"

[lolife99]

It's drum backing plate to drum backing plate.
Not the flange that the backing plate mounts to.

I would try bolting on a bare rim and taking measurements off that to be sure.
Or bolt the backing plates back on to use the numbers I posted.

Also make sure the rearend is centered in the frame.
