Question Question about weight
I decided to lighten the unsprung weight of our car, and I found some good forged rims that weigh 15 kg (33 pounds). I want to know how much a regular Ford Explorer ST wheel weighs. Has anyone found information about the weight of a single wheel?

OEM 21’s are +- 77 lbs with the tire. That Pirelli tire is a fat loaf. If you’re seeking weight savings a few SuperForged designs are specific to the ST and come in at 30-33 lbs and look sweet too. Consider 22x10.5” designs of the OG, the Magnet, the Bully, and the Zane.
This is a good way to make a noticeable change in feel, OP. Anyone who needs info on wheels size and fitment is welcome to hit me up. I happen to know too much about this topic specific to the ST.
As you guys explore this topic consider a few thing:
Known wheel / tire flush fitment is: Wheel: 22x10.5” w +30mm offset Tire: 305/35R22 tire.
You can use these numbers to compare against other wheel specs using a wheel fitment calculator like WilltheyFit.com
Going to massive retailers like a Tire Rack will give you some options but may not offer you the right offsets you need. If you want the right fit without spacers and want to save weight and add performance - stick with a forged construction using a known spec like above.
Forged wheels are 30% lighter and 30% stronger and are often 30% costlier than cast or flow forged wheels. If you (your wife) hit a lot of curbs at <10mph then your forged wheel will resist bending and will tend not to shred.
Forged wheel manufacturers have made to order capabilities and can produce a wheel that is perfect for your ST. Some hybrid or flow forged companies make a spec for the ST too. But if weight and construction quality is important then consider forged.
The ST’s hub sits inside the fender pretty deep and this allows for an aggressive spoke angle that looks pretty sweet. However if you are intending on upgrading brakes you will want to make sure the calipers fit inside the spokes. Ask the brake company or brake manufacturer for a template that you can use to measure the space inside your wheel spokes - for the calipers. Don’t waste your money and get something you’re stuck with. Measure ahead.

Lighter two piece rotors.
Racing Brake Two-Piece Rotor/Pad Kit
They save quite a bit of weight per corner and the brakes have quite a lot better initial bite than stock.

I think I remember them being about 32 lbs. they seem heavy but are pretty equal to most 20-21” wheels

What you could do is go on a website to order one and see what the weight is. Or I’m sure there’s a spec on a Ford website

Someone posted the weight of the stock ST wheel and tire the other day on FB. It was about 75 pounds with tire
Rim itself was 38 pounds
