+Julievonne The Pontiac G6 hubcaps have black plastic lug nuts that screw onto the lug nuts on the wheel. This would be referred to as a screw-on hubcap rather than a bolt-on hubcap.

Thank you for your inquiry. Yes, you can switch from a bolt-on hubcap to a pop-on style hubcap. However, we wouldn't recommend switching if you have bolt-on because pop-on hubcaps tend to fly off if hitting a pothole or different conditions of driving. Bolt-on hubcaps are held on by the lug nuts, therefore, are more secure on the vehicle.

Hubcaps.com Thank you very much for your hasty reply.

These are absolutely a lot harder to steal then a pop on hubcap because it takes a lot more time to remove the bolts in order to take off the hubcap. They do tend to last a lot longer then pop-on hubcaps.

+SpiffyNico Yes, you are able to switch out to a pop-on hubcap. However, if the hubcap has 5 lug hole openings, it will be off since your vehicle only has 4 lug nuts. If the hubcap you are considering does not have open holes, but rather "fake" lug nuts (decorative), then it should be fine.

+Ana Maria Dan Generic hubcaps and center caps can usually be found on Ebay or Craigslist. Often times, after market or custom wheel brands discontinue their wheel and caps over a period of time, which makes finding replacements rather difficult. Since we only specialize in factory caps, we usually also recommend trying a company, centercapsdirect.com, as they do specialize in custom wheel caps.

+Mark Hamilton Typically, yes you can. However, not all steel wheels are the same. In some instances, the pop-on hubcap won't snap on because that specific steel wheel was not meant for pop-on styled hubcaps. What is the year, make and model of your vehicle, so we can better assist you?

+Denise Jackson Unfortunately, Toyota has yet to manufacture a bolt-on hubcap for their vehicles. All of Toyota hubcaps are a pop-on style hubcap.
