18" wheel weight?

[Alpine]

Has anyone weighed these wheels or wheel/tire combo?

Looking at tirerack, the 18 inch tires weigh 16 pounds less than the stock 20 inch tires. 40lb vs 56lbs. That's 64 pounds weight savings of the best kind, unsprung rotational weight.

Also if anyone knows the 20 inch wheel weights or wheel/tire combo weights.

I believe the 18" inch steelies and tires is similar or same weight to the Cyberwheels and tires.

Below are the vehicle weight in old user manual that listed RWD specifications:

Not sure the weight of the 18" wheels itself, but based on the table. AWD All season tires which is the core wheels compared to all terrains which come with Cyberwheels is 17-18 lbs difference at front/rear axles, therefore calculates to 8.5-9lbs difference each wheel/tire.

When RWD was available, the option wheels were the Cyberwheels with All terrains. Table shows same curb weight for the Long range RWD with either All seasons (standard 18") or All terrains (Cyberwheels).


According to tirerack they list weight as:

Goodyear Wrangler Territory HT 285/70/18 = 40lbs
Pirelli Scorpion ATR 285/65/20 = 45lbs
Goodyear Wrangler Territory RT 285/65/20 = 55lbs

Steel wheels are pretty heavy so very possible its 15lbs heavier than alloy, thus Tesla listed the same spec.

The overall diameter of the 18in wheels is most likely the same overall diameter of the 20in core wheels with AS tires, since the rated mileage is the same when you pick either wheel. The weight won’t make much difference on an EV, drag will make more of a difference. I probably have a few hundred pounds of stuff I carry in my truck at all times and it has made no difference on range or efficiency since it’s all stored in the bed and cab. A spare for my CT, a spare for my wife’s MY, 12 ton Jack, charger, cords, air compressor, tire repair kit, a bag of hand tools, frunk cooler, various cleaning supplies, hitch balls, shackles, straps, many tie down.. and that’s just what I can remember, but I’m sure there is more. My current efficiency is 366 with 9300 miles.
now if you get the 18s and get lower profile tires you would probably add range in 2 ways… easier to spin smaller overall diameter wheels and you would be lowering the vehicle some too so possibly less drag under the truck.
There was a guy on YouTube that tested range with weight and with a pallet of shingles in the bed it lost about 4%, which is the amount you loose for having the tonneau open, when he had open due to the pallet of shingles.

Here is the stock 20” core wheel and tire on the scale. Showing 78.4 lbs. now there are some variations from wheel to wheel but this gives us an idea. Now we need someone with the 18” set up do the same
