No doubt you could use them. It's not like they're expensive anyway. You really do want the wheel centered, not floating. Keep in mind the studs weren't intended to support the entire weight of the car, that's why the OEM wheel centerbore is the same as the hub centerbore. The other thing about conical lug nuts is the need for a decent torque wrench to install the wheels is much greater to ensure the load is evenly spread across all five studs. Tightening by hand and guessing at torque isn't recommended.

Q: Exactly, what does hub centric mean?
A: Hub centric wheels are manufactured so that when they are installed on a vehicle, the wheels are located directly off of the center flange of the brake drum or rotor. This is done to insure that the outer beads of the wheel are concentric with the wheel bearings. The result is a much truer, better balanced tire/wheel assembly. This is very important with modern high tech suspension systems.
Q: What about the phrase “Lug Centric”? Isn’t it just as good?
A: NO! Lug centric is a marketing phrase made up by the few manufacturers who don't offer hub centric wheels. Their theory is that if the wheels are drilled for conical seat lug nuts, then the wheels will self locate. Surveys have shown that most installers just hang the wheel/tire combination on the studs and put on the lug nuts expecting the angle of the conical seat to pull the wheel/tire combination into concentricity.
Recent tests by several major wheel manufacturers have shown that when the above mentioned mis-locating occurs the studs actually bend down slightly thus creating an artificial out-of-round condition by as much as .0025. Consequently the custom wheel often gets a bad rap
because of a poor installation job. Hub centric wheels or hub centric rings will correct this situation.

Go to America's/Discount tire and spend $15 for some hub rings. Most aftermarket wheels are made with a 73mm hub size so they can fit most any vehicle's hub, and your Lexus has a 60.1mm hub size. Verify the hub size with Work USA, or you can wait until you get your wheels and either measure the hub size yourself or have Discount tire/whatever shop you buy from measure it for you. Assuming Work makes their wheels with a 73mm hub size, you'll then need a 73-60.1mm hub ring. Get the plastic ones - they're cheaper and like Lance's link mentioned above, and they're actually better than the aluminum ones.Javier

You COULD go without hub centric rings. I know lots of folks who don't use them. At the same time, I don't think it hurts to get them. They're inexpensive and they give you peace of mind. I personally decided to buy them because I don't think it hurts to ensure that your wheels are more precisely centered. Just my opinion though.
