How we price

Asking prices, not sold prices. We record what sellers ask on public listings. We do not know what the part finally sold for.

Typical range. The middle half of asking prices. A quarter of listings are below it and a quarter above.

At least 5 listings. We only show a number when 5 or more listings back it. From 20 listings, the highest and lowest 5% are dropped first.

Factory take-offs lead. For wheels and tires, the headline number uses factory sets only. Aftermarket sets are shown separately.

Deals. A deal is a listing priced below the typical range for its part. Listings under 40% of the median are not counted as deals, because at that price it is usually a single piece or a parts lot.

eBay. eBay listings are shown with the seller's photo, but they are not counted in any price yet. Many eBay results are small pieces of a part, so we only show the ones priced like the whole part.

What is left out. Stores selling new products, single wheels or tires, listings that fit several vehicles, and vehicles outside the years we cover.

Size matters. Wheel diameter and tire size are read from each listing, because they change the price more than anything else.
