OEM vs aftermarket alloy wheels
OEM wheels are made for your car. Aftermarket wheels offer more designs and sizes but need more checking. Here is how to weigh them.

What is an OEM wheel?
OEM means original equipment manufacturer: the wheel the car maker fitted at the factory, or an identical one. It is designed for your model, so bolt pattern, hub bore, offset and load rating are already right.
What is an aftermarket wheel?
An aftermarket wheel is made by a different company, usually for a range of cars. Choice of design, finish and size is much wider, and prices span a wide range.
Which is easier to fit?
OEM wheels are easier, because the fitment is built in. Aftermarket wheels need you to confirm the bolt pattern, hub bore, offset, width and load rating yourself, and sometimes add hub-centric rings.
How do I judge aftermarket quality?
Look for a known maker, a stamped load rating and the standards marks on the back. Be careful with unbranded wheels that have no markings. Cheap copies may be heavier and weaker.
Which should I choose?
Choose OEM for a like-for-like replacement. Choose aftermarket for a different look or size, and spend the time to check fitment. Both are available as used sets on WheelStop.
Does fitting aftermarket wheels affect my warranty or insurance?
It can. Rules differ by manufacturer and insurer, so ask your dealer and insurer before you change wheels, and keep the original set in case you need to refit it. Keep receipts and specifications for the new wheels. Larger or heavier wheels can also affect ride and braking feel, so test drive after fitting.
