Rear tire clearance - The 1947 - Present Chevrolet & GMC Truck Message Board Network

vet57air · 02-12-2021, 08:01 PM

Was wondering how little tire clearance guys have gotten away with on the rear tire to fleetside box sheet metal? My tires are 31" tall and I have my truck very low. Being so due to the shape of the box side I want to get it as close as possible to the box as some of the slammed trucks I have seen look a little odd with a narrow track width back there.

For a fleetside. The tightest spot is where the seam runs down the box side horizontally. Normally stock tires are under this so there is no issue. My large diameter tire along with being so low it is.
I believe I could be as close as a 1/4" as I have a 4 bar suspension and really only have about 3 1/2" of total suspension travel. But would like to hear of others experience.

I don't remember.... Is the seam between the upper/lower bedside halves trimmed @ all or untouched on yours? 1/4" is pretty tight. If you leave it @ that gap, is the seam visually exposed within your bed set-up?

I plan to trim mine back 1/4" so the spot welds are still intact but allows the tire to be as far out as I can w/an extra 1/4" of clearance (mine measures out @ about an 1/8" gap w/the seam untouched). My seam in that area will be hidden by the tubs though.

I did trim my seam. There is about 1/2" remaining which I added material to for strength, then welded all along. It is hidden under the tubs. The long story is there are a set of the same wheels available cheap that have 1" less of backspace than mine. I just got the wheels in and have 1 1/16" of clearance to the seam with the present wheels. Thought I had more. When I measured for my wheels I had not cut the seam and had 1/2" of clearance. I like the wheels out as far as I can. I would be happy with 1/2" of clearance but to use the other wheels it looks like I would have to narrow my rearend. Or just leave it.

So this is my rear tire in place with the 1" clearance. To give some perspective the tire is 2 1/2" from the box wheel lip at the top center. They are 22" x 12" with a 325/35 tire. Is it to far in, should I leave it or.... OMG I going to give myself an ulser.

Give us a picture of a front 3/4 view, so we can see the "offset" in front AND in back.

From this view, I think it's perfect. But I need to see the wheel placement front AND back.

I have 2-inch bump stops front and rear so I can drive it just in case. Otherwise, the rear wheel tubs and the front inner fenders rest on top of the tires.

I think it works with the front. If you pull the rear wheels out more, the fronts will really look shoved in. The fronts still need to steer, so they kinda need to be where they are.

If you pull the rear wheels out more, it might be harder to remove a wheel, if you don't have enough droop travel.

I like it the way it is.
