Everyone knows that getting some rims for your Cadillac STS is the easiest and most effective way to make it stand out from the sea of stockers on the road. Whether you're plus-sizing to some large Cadillac STS rims or simply getting a different style of Cadillac STS rims, you can't lose! You can get lightweight Cadillac STS rims or cost-conscious replacement Cadillac STS rims depending on what you're looking for — it's all up to you!

Aluminum Cadillac STS rims tend to be lighter than their steel counterparts, but not all aluminum wheels are the same. They can be cast or made from billets, and some are even forged for extra strength!

Steel Cadillac STS rims are usually heavy, but they are also strong and relatively inexpensive. A lot of vintage style steel rims that were available in the past are becoming popular again, and wheel manufacturers are taking advantage of this by reintroducing styles that haven't been available new for years!

No matter the rim material itself, they are all generally available in various types of finishes, such as painted, powdercoated, polished, and even chrome. Of course, the end user may even choose to have their new rims refinished to a custom color to perfectly match their ride!

Q: How can I find out the size of wheels that are currently on my vehicle right now?
A: To find out the size of the wheels on your vehicle, you can actually look at your tires. There is a reading on your tire that looks like this: 225/45R15. The last two numbers (15 in this example) indicate the diameter of the wheels on your vehicle.

Q: Do the wheels listed on the Andy's website come with tires?
A: No they do not. Tires are sold separately in the 'Tires' category of our website. If you are buying wheels that are the same size as the wheels already on your vehicle, then it won't be necessary to get new tires anyway.

Q: Are the wheel prices listed on the Andy's website for four wheels, or for each individual wheel?
A: For every wheel we sell, the price is for each individual wheel. So in the likely event that you want four wheels, make sure to adjust the quantity to "4" in the shopping cart after you've added your wheel of choice to the shopping cart.

Q: How does Andy's know which wheels will fit my vehicle?
A: We set up some sophisticated database functions to compare fitment information against wheel product information. We take the factory wheel and vehicle specifications of a given vehicle, and use those to determine the range of sizes that would comfortably work for that vehicle. We then load the wheel product data from a given brand of wheels to our database, and within our database we built functions that automatically calculate which wheels meet the fitment criteria of a given vehicle. It’s all pretty scientific and mathematical, but by the time you open the Andy’s webpage showing the wheels we carry for your vehicle, all that computing has already been done for you and you can rest assured any wheel we list for your vehicle is guaranteed to fit!

Q: What is the best size of rims for me to buy for my vehicle?
A: This sometimes is the most daunting question that buyers face. On one hand you want rims that are big enough to give your vehicle a clearly custom look that differentiates your ride from others on the road. On the other hand, you don’t want the wheels to be so big that the only way to stuff them under your fender wells is to use ultra skinny tires and thereby affect your ride quality. In our experience, a safe rule of thumb is that you can comfortably increase the size of your wheels by up to 3 inches from the factory size without it impacting ride quality negatively. So if the factory wheels on your vehicle are 14 inches in diameter, you can comfortably get rims that are up to 17 inches in diameter without negatively affecting ride quality. Of course, you are welcome to go much bigger than that, but in doing so you might be making a sacrifice in ride comfort unless you modify your vehicle in other ways to 'handle' the big rims better.

Q: Do wheels come with valve stems and lug nuts?
A: Unless otherwise specified, neither lug nuts nor valve stems are included.
