It's an industry thing. When a consumer provides their vehicle for replacement tires the tire installers are going to compare the consumer's replacement request with the vehicle certification information. To follow industry standards they can't use tires with a different size designation without vehicle manufacturer approval, it constitutes a misapplication of the replacement tires. Normally they will consult their computer files to see if their are recommendations from the vehicle manufacturer. If not they may contact them for verification.
When a consumer walks in with their wheels in hand it frees the tire installer from performing a misapplication. All they have to do is verify the wheels and valve stems can withstand the load and pressure ratings of the replacement tires and that the tires are appropriate for the wheels. The bill of sale is not going to show any vehicle identification or VIN numbers.
