Can I use 22" Platinum wheels on my Lariat ER without making any adjustments on the truck?

[AJ Tuli]

Lariat has everything I need but i like 22" Platinum wheels. I was thinking to use 22" Platinum wheels for winter tires and 20" current wheels for summer tires.

Just want to make sure i can swap between these wheel sizes without changing anything on the truck.

I would do it opposite, but you do you. The range hit with the Platinum wheels, combined with lower winter driving efficiency, would be a double hit.

Yes. You can swap between them with no problems.

Yes.

Plus you can find 22" all season / "summer" tires reasonably priced, but 22" winters are a lot more expensive compared to 20" or even 18".

I bit the bullet and got new tires for both 22" (all season) and 20" (winter) and then sold the general crapper that came with the truck.

I run Lariat wheels in the winter and Platinum wheels in the summer. In theory the difference between Platinum range and Lariat range is about 0.1 m/kWh. I don't detect the difference.

Platinums have stiffer springs than the rest of lineup. That may or may not make a difference when going from 20" to 22" wheels. I haven't spent any time in a Lariat so I can't speak to the ride difference other than to note it.

The tires on the Platinum are 32.83" in diameter vs the 20's being 32.99". That .5% difference. I don't see how that's going to make the range drop from 320 to 300. Doing the math yields less than 2 miles of range difference.

Only if you want a significant drop in efficiency. Electrical vehicles should *never* have boat anchor wheels and those things are HEAVY, 50 pounds apiece.

You can get a better looking set of wheels that weigh almost half that, greatly improving your efficiency. I eecommenOnly if you want a significant drop in efficiency. Electrical vehicle should never have boat anchor wheels and those things are heavy, 50 pounds apiece.

It's not the circomference / diameter that does it, it's the weight and aerodynamics / drag.

Only if you want a significant drop in efficiency.

I suppose the significance is relative, going from Lariat 20" to non-aero Ford Performance - boat anchor, 22"s I lost less than 10%.

Plus I didn't think they ( Vorsteiner / Venomrex ) made 22"s if that's what OP has his heart set on.
Plus, you can buy a lot of kWs for the price difference between a set of Platinum take-offs and a new set of premium lightweight wheels and new tires.

Really? I'm not buying it. Has anyone actually proven this, or has Ford stated this as being the sole reason the Platinum's range being reduced?

the reduction in range is from weight and unsprung mass of 51lb wheels. Simple physics. Takes more power to spin 51lb wheels up to speed.

I switched to lightweight (28lbs) and have mileage/season confirmed 10% gain over 11,000 miles 2.1->2.3+

Interesting results!

I'm sure what you say about wheel weight is true and important. The physics are a bit more complicated, though, in that range will be affected by wheel mass, and aerodynamic drag, and rolling resistance. If you're driving in a hilly area and doing lots of acceleration and deceleration, weight should make a greater difference than if you're mostly cruising on level highways at a constant speed.

Is there any difference in the width of your lightweight wheels compared to previous ones? That should affect aerodynamic drag quite a bit. As for rolling resistance, estimating the effect of wheel changes on that is out of my wheelhouse, (sorry...couldn't resist) except that higher pressure is widely known to help.

I always welcome learning something new., so I did a little research. Didn't realize how much more this effected EV's more so than ICE vehicles. Sounds like Ford is overdue to redesign the Platinum's wheels.
