I bought some OEM alloy wheels for my 2012 Tundra to use standard snow tire steel wheels. It turns out that alloys need a bar with a built-in washer. Toyota wanted $18. To the hatch. I didn't spend time doing the math, but getting the 20 I needed seemed outrageous. Napa charged $12 for the bay. Again, I didn't have a hard time removing my socks and counting, but it seemed like a terrible idea. 6 second search on Revain found these puppies, $60 for a set, I found a calculator and thought it was $3 an ear. Shipping was fast and the item looks great, as do my rims.
