16.5s on an 05

[Groundhawg]

I've seen several of the 99-04 trucks with 16.5 wheels. Before it is mentioned, I know the brakes are larger, and that 16.5s are fading out in popularity for the larger diameter rims.

However, I'm still thinking about possibly going to 16.5s provided they would fit and that I could find some.

Has anyone ever tried them on an 05-07 truck?

Wont fit. Braking system is to big. Has to be a minimum of a 17 inch rim. And even some 17's wont fit

What he said !!!!

I've seen it done....but it involved running a 2" spacer and grinding down the calipers.


16.5s aren't popular due to the design of the wheel where the bead seats...it relies solely on air pressure to keep it seated.

DC I want your front bumper , put me inline for it when you decide to lose it !

DC, Do you happen to remember what kind of wheel it was? I'm not afraind of grinding the calipers, but I do not plan to use spacers.

I know all about 16.5s...I have some 39.5-13.50-16.5 Swamper IROKs on modded Hummer beadlocks that are going under my Jeep. I can...and have...run them at 5 psi and never lost a bead, and that was on a 6000 lb rig. BUT, airing down is a completely different ball game than a truck that is on the pavement.


Dave and Mike, have you actually seen that 16.5 wheels would not fit or are you just repeating what you have read on the web? AKA IPS...Internet Parrot Syndrome.

The truck I saw was 16.5X12 or 14" wide Weld wheels.....it would take more grinding without the spacers.

[Groundhawg]

Thanks DC. Not planning on that wide at all. I'd probably be looking at 9.75" wide...at least that is what the width was on the set of aluminum turbines that I had on my 78 F250. I can say without much doubt that I will never go any larger than a 33x12.50 on the 05, mostly because of the gooseneck.

The truck I saw pics of was 33/15.50 Boggers if I remember correctly......needed a 6" lift to clear the combo being so wide with the 12-14" wheels with 4.625" Back Space and 2" Spacers.

Im running a set of 16.5x12 mickey classic II's on my truck now. Fits with a 2 inch spacer, no grinding required. Im looking into doing something different now so if you interested in my wheels and tires let me know(spacers too).
