I know... another rim thread...

I've searched and searched and searched this site, google and other places... so I'll stop users right here from commenting on using the search function - I've used it and come up blank.

Anyone able to comment on the fitment of a 16" 1994-2004 Dodge 2500 rim on our dentsides to replace the 16.5" rims? I took some measurements last night and losing a 0.5" in total actually looks like it might make the caliper rub on the rim... not to mention if backspacing is an issue, then the caliper will REALLY rub on the rim.

Anyone have any thoughts or experiences on this?

I've seen plenty of 16" wheels go onto dents without problems and am just upgrading mine to Sunraysia type steel wheels. Of course this may vary between trucks so I'd definitely try and get some measurements of the actual wheel...

...are you running aftermarket brakes? Factory discs? Or stock drums?

in reading through some old threads, I don't think you'll have any issues. I think they'll look good on your rig.


Although that price seems a bit high, but I am sure that is more driven by the region you live in.

 

Yes, 16" rims will work but will clear the calipers by < 0.5." A very close clearance. I know because a while back, I had to use some 16 inchers in a pinch.

 

The only thing I'm certain you will find is the dodges use 9/16" studs rather than 1/2". The wheels I'm using that you had asked about were also 9/16". The 10.25" rear I have has 9/16" but my d44 still has 1/2". There's lug nuts out there made just for that. I don't know where I got them but they were like $1 a piece. There's another $20 I forgot I spent whoops.

 

Can't help with the Dodge rims but I'm running 235/85-16 tires on 16" white spoke rims on my '74 F250. They did rub on the fenders until I rebuilt the front end, except for springs.

 

Here are mine: These are 16x8 LT315/75R16 BFG All-Terrain T/A KO2's.

The axle is a Dana 44 from a 78/79 F250 so it is basically the same as yours. Not sure about the Dodge offset and backspacing, but the wheels I am using have no clearance issues.

 

I know that the two wheel drive 78 f250 Ranger that Dad bought new had 16" wheels, also the 76 Custom high boy that his friend bought new had them.

Most of the Fords that I remember from that era had 16" Lock Ring wheels stock.

IIRC the standard 7.50-16 tire was about an inch taller than most of the 16.5 tires.

As to whether those Dodge wheels will fit, the only thing I can suggest is to jack up the front end and try one. You don't need much clearance for the brake caliper, but you do need some.

Just like Lasermike I have 16" steel wagon wheels on my 75 f250 2wd and no clearance issues. Some aluminum wheels might be a problem due to back spacing. Didnt the tire sizing chart help, It's of no use for duallies so I dont use it.

 

Forgot to mention I have dual piston calipers if that makes a difference.

 

Had to step up to 17's on mine. 16in rims hit the calipers.

 

Sorry fellas, late response because it was a very busy weekend.

I've also seen 16" rims go on our trucks, but I chose to pass on these ones. They wouldn't have cleared the calipers.

I'm running front factory dual piston calipers.

Price was high, and I didn't want to take the chance of hitting the calipers, so I passed on them.

Love those rims. Wish I had the $$$ to shell out for a set just like them right now.

If those rims were ordered for a Ford, then they'll have approximately 0mm or even a negative offset to help clear the calipers and assist with rubbing when turned full chock. Positive offset is what keeps killing us Ford lovers...

Dodge offset is approximately between +40mm to +60mm, whereas almost all of Ford's stuff up to 98 (which fits our trucks) was 0mm offset.

The dodge backspacing is a bit too great for our trucks I believe, unless you don't care about rubbing on the leafs/springs.

Yup! It certainly does!

I noticed a couple of small pieces protruding out from the caliper surface that would have likely created clearance issues if a rock got lodged between the inside of the rim and the caliper... which I wasn't really a fan of even though I won't be doing off-roading.

I'm going to try 17" rims as well... 16's just seem much too close for my comfort.




Thanks for the responses everyone.

In the end, I passed on the rims in the ad. $300 for potential clearance issues is a lot of money to shell out to only have to re-sell again.

I did some measuring with the rims on the truck and it appears that FORD gave us approximately 1" total clearance with the 16.5" rims on an F250 with dual piston front calipers. That means that there's actually only 0.5" clearance (half because 1" is the diameter measurement) between the inside of the rim and the caliper.

Using a 16" caliper would reduce that clearance to close to 1/4" which is simply too close for comfort for me... not to mention that all of the reading I've done on the threads says that backspacing is a bigger issue.

The backspacing for our trucks is meant to be a MAXIMUM of 4.5" in order to have ZERO issues with rubbing on the leafs/springs when the wheels/tires are turned to their maximum (chock to chock).



Those dodge rims I looked at were 7.5" wide, but had a +43mm backspacing... Using some quick math from another thread...

Backspacing = 1/2 x Rim Width + Offset + 1/2" (for clearance/errors in measurement)

Backspacing = 3.75" (95.25mm) + 1.7" (43mm) + 0.5" (12.7mm)
Backspacing = 6" (150.95mm)!!!

There's no way that those rims would have properly cleared my front calipers with a 6" backspacing. The inside lip of my current 16.5" rims already looks like it would rub on the caliper IF it had a positive offset of about 15mm (1/2"), and the backspacing on those rims is approximately 4".

So now I'm looking at newer dodge wheels since they're generally 17" rims and have the 8x165 bolt pattern we desire.

However, backspacing, again, will be the main issue.

Is anyone running wheel spacers to help accommodate the limited backspacing we have on our trucks?

 

I just looked up my wheels again to get the specs for reference in case somebody in the future is looking for 16" wheels :

Pro Comp Alloy Wheels - Series 1069, 16x8 with 8 on 6.5 Bolt Pattern - Polished | 4WheelParts.com

They are zero offset, 4.25" backspacing 3420lb rating. I have dual piston calipers as well. I'll need to measure the clearance, but visually I didn't notice any problems when installing.

 

I'm also running those Pro Comp 1069's with 315/75r16's KO2's, but in a 16x10. Don't have a pic, but the dual piston calipers clear the rim by about 1/8". Tight, but work just fine.
