Can a wall support 2 hanging tire racks on the same studs?

[Accel Junky]

I'm curious...I've got small wall in my garage that is basically dead space and I'd like to mount my two tire racks on it. One right on top of the other. So there would be something like 4 or 6 studs with about 500 lbs hanging at least mid to higher up on them. The other side of the wall is just the pantry. Above is a stairway foyer and closet. Think this is safe to try? The racks are the common square tubed metal pieces that have side load rubber pads that go against the wall.

Would look something like this:

\...ceiling...\

\ [RACK] \

\ [RACK] \



\ ...floor... \

If you are using 4 or 6 studs I would offset the tire racks so they weren't sharing the same studs but could still be on the same wall. So with 4 studs; tire rack #1 would use studs 1 & 3 and tire rack #2 would use studs 2 & 4. That way you're not as likely to affect the integrity of the wood and the loads would still be "spread" over 4-6 studs.

Get it?

Why not make a support from the outermost part from the rack that would support from the floor, halving the load on the wall. If you don't want them sticking out, make them angle back towards the wall meeting the wall at the floor. wall | |leg or wall| /angled leg.

Thats a really good idea but I am not sure it would be any better. I don't material properties of a 2x4 though.
Bear with me as I work this out; Given 2 600lb racks across 6 studs. Each rack is mounted at the top and bottom so each rack has 2 load points/stud.

I am going to assume equal forces from all mounting points even though I know its not true due to top and bottom forces being different. Also with an offset pattern the end rack is holding more beyond the mount.

For offsetting the racks, so rack 1 on studs 1,3,5 and rack 2 on studs 2,4,6
Wouldn't 600lbs across studs 1,3,5 be 200lbs/stud or 100lbs/mounting point (Top and bottom on each stud)
This seems like the same as racks 1 and 2 on all studs, so 1200lbs/6 studs = 200 lbs / stud. But then we have 4 mounting points ((1)top rack 1, (2)bottom rack 1, (3)top rack 2, (4)bottom rack 2) so it would actually be 200lbs/4 points or 50lbs per point.
This also gives better weight distribution at the cost of more screws going into the 2x4.

OP - I would say you have absolutely no issue as it would be downward force and any side force is much smaller and the top of the wall will be able to hold that just fine. I am trying to think of much heavier things hung off walls, but am drawing a blank, but you are fine. Just build it right, and the wall will be fine.

Don't worry about it. Not worth over thinking it. ~3-400 lbs of tire isn't that much load.

If there is a strength issue, the lag bolts will pull out before the studs break. The studs are going to share load through the exterior sheeting and the interior drywall.

If you are worried about the loads, run a wire from the outside corners of the racks to an eye bolt hanging from the ceiling truss or the rim joist.

Thanks for the responses. It would be about 600lbs total between the two racks (not 600 per). I will give it a shot because this wall is relatively out of the way from the others. Would rather keep the good space for bigger and better things.

The floor support idea is good but I want to keep that floor space available for whatever may go there. Maybe my push mower since I don't want it taking up the good space over where my tool chest, bench etc... are.

Yeah - just mount it up. If you see the wall flex when you load it up, then just bolt up a sheet of 3/4 ply to share load with multiple studs or something like that. (or wire hangers or something.)

 

[Accel Junky]

Ok guys...I went for it. So far so good. Nothing seemed to flex so we'll see how it goes.

There are actually 5 studs used with the middle stud having two lag bolts per rack. So each stud is getting about 110lbs of weight per. Seems pretty reasonably to me.

I wanted to make use of a small little section of wall near the ugly water heater and leave my bigger sections of walls for cabinets or automotive art or whatever.
