As of February 2015, the Sam's Club website has a search tool that provides the type of tire that fits a specific vehicle. Once the year, make, model and tire size is imputed, it searches through the available tires for the vehicle.
There is a tab where the shopper can decide to view all items available online or just the ones available at a specific Sam's Club location. The search can be refined further by brand, price, shipping included and service description. The results are sorted by default by most relevant, but brand, member rating and price sorts are available.
