Electric Windows Configuration.

[kvermeer]

If you order power windows, I would almost guarantee they will ship you the truck with crank windows, and you will just make the conversion yourself. The single config allows them to be more efficient.

They specifically say in the FAQ:

> You can choose to have the SUV kit installed prior to delivery or purchase the kit later on. If you choose to purchase it after delivery, it can easily be installed by your local Slate service provider or at home following our video tutorial.

and

> You can choose how and where your accessories get installed:

• DIY: easily install accessories at home with Slate University, our library of video tutorials and helpful how-to content.
• Before delivery: get select accessories installed at the Slate delivery partner.
• At a service partner: buy accessories after delivery and get them installed at your local Slate service location.

I'm not sure which accessories are "select", I read that to mean that the SUV kit/fastback kit is at least among of them. I'd wager it also includes a handful of other major items, like bumpers, wheels/tires, and suspension lifts/lowering kits. I'd also guess that window cranks are not among those select items.

IMO, you should be awarded credit back for returned stock parts if you get accessories installed prior to delivery. Otherwise they're going to have a ton of wasted 17" steelies and base-model bumpers and so on. It's still a little wasteful to receive a Slate with a window crank handle you never intend to use, but not nearly as bad as a whole bumper or something like that.

Also noticed for the first time that it says "installed at *THE* Slate delivery partner" not "installed at *A* Slate delivery partner." Another indicator of a Carvana/SilverRock partnership? That makes me believe it's not just a freight provider but some company that has automotive service centers. I know RepairPal service shops can install accessories after the fact, but they don't have a delivery network. If Carvana/SilverRock can also do repairs, that would be a huge expansion of the Slate repair network!

FWIW,, the JD power data on window systems rates power windows as more reliable overall, some manufacturers have had issues over the years, but the power has the better average. I saw it a couple years back.. almost no cars or trucks currently have manual windows.

I’ve never had to fix a crank window but I have replaced several power motors and regulators.

when you crash your car in a lake, manual windows are great.

All these extra parts could be beginning of spare parts. Those with steelies may be selling to others as a spare, maybe me.

I would buy a set of steelies to put winter tires on them.

That's my plan. Winter tires on the steelies and find a different wheel/tire combo for dry weather. I haven't seen anything on what the Slate lug pattern size is.

I haven't either, but I bet you could measure it with photogrammetry. The BSD of the 17" rims and OD of the tires are well known, there are several good high-resolution telephoto images of the tires from perpendicular to the truck, measure the ratio of pixels across the tire and the pixels through a circle across the lug nuts, and a bit of math later you could figure it out. I'm on my phone or I'd do it.

Makes you wonder if Slate might change this from prototype to production...

When I asked them a few months ago about the wheel specs they said they had not yet been finalized. They may have by now, you can either ask slate or maybe we will know in a few more days.

Ugh…will pray that any knocks to the head don’t preclude using cranks vs safety hammer at only the right level of submersion.

I’ve been driving since 1969, haven't run into a lake yet… of course I don’t drive drunk or drive like I have no sense.

I made a gameful effort of it with some of the photos of the fifteen52 wheels on some of the demo vehicles. The problem is that I kept getting a BCD of 116 to 117mm, which is halfway between the two common sizes of 5x114.3 and 5x120... I could massage my calibration up or down a bit to hit either of those two dimensions, but couldn't get precise enough to confirm which it is. 3mm is pretty tight to measure given that none of photos are 100% straight on, or completely free of distortion.

The fifteen52 wheel they listed is available stock in the 5x120 size, but 5x114 is common enough that most wheel manufacturers would be happy to make batches in that drilling pattern. https://fifteen52.com/products/analog-hd-asphalt-black?variant=41203780190274

And of course, you could do all the sleuthing perfectly and then find out they changed hub suppliers for the final version. I'll just sit tight and wait.

EDIT: I know there are also 5x115 and 5x118 and 5x120.6 out there, but I'd be surprised if Slate chose any of those as they are far less common.

If you're going from the lip of the rim, you have to add about 35mm (depends a little on the wheel) to your diameter - 17" is the bead seat diameter, not lip to lip.

I used the "Blank Slate - Cutlight Detail" from the press kit which was pretty square to the wheel:

and measured 1187 pixel diameter at the lip (1182 horizontal, 1192 vertical, average to 1187) with 305 pixel BCD at the lug nuts. That maths out to 119.944mm before any massaging, close enough to 120 for me to be pretty confident that's the nominal size.

I checked against this image from this thread:

The math on that one says 646 px lip diameter and 166 px BCD, which maths out to 119.951, again, close enough for me!

A few caveats: I don't think they'd change the hub pattern, but those are March and May 2025 images, not recent. And the first one is a BFG all-terrain tire, not a Kenda - BFG do make lots of 17" tires, including a 245/65R17. Most importantly, we don't know the offset, so we can't order rims yet! I suppose you could order wheel spacers for your widebody mod, but we don't know hub center bore diameter either. And, maybe most importantly, these are Slate-branded steel (steel appearance?) rims, not the aftermarket aluminum fifteen52 rims they've been using on the prototype trucks at events.

 

[phidauex]

Ah, nice, that is a better rim lip OD estimate than I was using. Your measurement combined with the stock size of 5x120 for the fifteen52 rims is pretty convincing that the size is 5x120, 17x8.0, 25mm offset, minimum counterbore no larger than 72.56mm.

Minimum counterbore could be smaller, with a spacer in there, and different widths could mean slightly different offsets, but it is a realistic place to start.

Wouldn’t place any orders until we have final specs of course!
