Hey guys, im looking to replace my stock 16x7 wheels with 17x9 wheels. After doing quite a bit of research, i learned that alot of our trucks are hub centric, and most aftermarket wheels are lug centric, with a bigger center bore than the diameter of the hub. In the end, i decided i want to retain the hub centric setup, as doing otherwise risks shearing off the bolts, and i'll be towing a 36 foot 5th wheel.

Anyway, finding hub centric wheels for my truck is downright impossible. However, i think i found some that will work without hub centric rings, but im not sure. Hoping you guys can help.

The center hub on the truck measures 124.9mm and the wheels i found have a center bore of 125.20mm. Is the difference here negligible enough to mount the wheels or do i need to match the center hub diameter exactly?

Thanks in advance

 

.2mm is .008 thousands difference.

 

@Tugly just went through this a few months back.

I think you'll be fine with lug centric wheels as long as you torque the lug nuts properly. I've run a few sets of lug centric wheels (16x8 & 16x10) and haven't had a problem. I don't tow a 36 foot 5th wheel, but I've towed fully loaded peanut trailers which are anywhere from 10-12k pounds, and had no issues. Also, while running the wider wheels, the truck was 100% more stable than it is now with the stock wheels and 305/70/16 tires I'm running...

 

Hey thanks for the reply, do you have any vibration issues?

 

I appreciate the reply, however this does not address my question, in fact, im not sure your response is accurate. My math comes out to a .3 mm difference which is 0.011 inches.

 

My math is this. .1mm divided by 25.4. Which is .0039 and change. I rounded up the .0002.

But yes .3mm is right around .011...or .0055 per side. How close would you like them to fit? Like a close slip fit, or a press fit? What do you suppose the manufacturing tolerance is on the wheel hub?

.011 clearance I'd run them, but that's me.

 

There has been a couple good threads on this and myself, like you, wanted hub centric which is the reason I chose to go with the 2004 18x9 Lariat wheels. Offset and hub diameter is made for our trucks and they look great with a 275/70/18. They were only offered in the last part of 2004 as Lariat, Harley Davidson and SVT wheels. I got mine on Ebay and I am very happy with them

 

I did have a slight vibration issue when I had the 16x8 wheels on and was running 315/75/16 mud terrains. But that wasn’t a wheel issue, that was a tire balancing issue...as in I didn’t get the tires balanced. Two months later I was rotating the tires and got my buddy who works at a dealership to balance them. Ever since I got the tires balanced, the ride was smooth as silk...well as smooth as a 3/4 ton leaf spring truck can be lol.

 

My F-350 and my buddies F-250 both run lug centric wheels without issue. 37" tires on both, both have carried heavy loads, both have been off-roaded. My F-350 got some fairly hard core off-roading and towed 13k lbs. with about 1500 lbs. on the hitch.

 

I went lug-centric about 10 years ago with no issues. Just make sure you get lug nuts that are long enough.

I kept an OEM wheel as the spare so kept a set of hub-centric lug nuts to use in case I had to use it.

 

I just want a proper fit, i have no idea what the tolerance is on the stock wheels, i am having trouble finding that information. Hoping someone here might know...

 

Brian, do you do much towing?

 

I don't tow much. Heaviest I think I've done is a loaded closed box U-Haul pushing 8K lbs or so. I wouldn't hesitate to tow heavy with the lug-centric wheels though.

My lug-centric wheels were a perfect fit (8x170mm bolt pattern).

Each wheel was good for 3400 lbs load and I kept on par with stock geometry. I got 16x8" rims with a -6mm offset and my OEM wheels were 16x7" with a +6mm. My new rims were 1" wider with the offset moving 12mm (~1/2") keeping things pretty close. It moved the wheel out a tad but that kept me from having any clearance issues with the front springs.

You just need to make sure you get the right lug nuts and the center caps are what you need. The front ones need to be open to operate the hubs if you want and the rear ones need to be long enough to go over the axle housing. Ultra didn't carry the ones I needed but the tire shop had some extras laying around in the back and sold them to me for a few bucks and put them on.

 

I have decided i would like to stay hub centric. As mentioned before, i found some wheels that might work, but i cant find any information on the stock rim bore size or the tolerance. I even tried calling the dealership lol. Anyone know the stock bore size?
