Why forged? Forged wheels start out as a single piece of metal called a billet. Because mono-block billets are not heated to liquification and poured into a mold like cast wheels, they retain their grain refinement meaning they retain their innate strength. Forged wheels are shaped by pressure, heat and incredibly versatile CNC milling machines capable of the most intricate designs with tolerances as tight as 15 microns.
Put another way, forged wheels are the result of manufacturing by subtraction. The wheel, complete with concave design, spokes, bolt pattern and all the rest, exists inside that solid metal billet. All you have to do is remove all the stuff that isn’t the wheel. And that’s what CNC machines do. Forged wheels are not cheap, but then perfection rarely is.
Who makes them? Here is a list of the top 10 luxury forged wheels who have been mounted on Lamborghinis, Corvettes, Ferraris, Escalades, F-150 Raptors and every other hot luxury ride.
