I have received two quotations for new winter tires and rims.
For identical tires (225/60R17 103T), one of them supplies a 7 inch wide rim, and the other a 6½ inch rim.
Why would the widths be different and what effect would that difference have?

I was looking at the problem backward, assuming that each tire had a specifically required rim size.
Cars already have rims and it is usually the tires that need replacing, not the rims.
So normally, the rim size is already known and one looks for replacement tires that will fit that size rim.
And rather than requiring a specific rim width, each tire is designed to fit a range of sizes.
In my case:
Specification … … Rim Width Min (in) 6.0 Rim Width Max (in) 8.0 Overall Diameter (in) 28.0 Width (mm) 225 Profile 60 … …
So these tires will easily fit either of the quoted 6½" and 7" rims (with 7" being the most "natural" fit). The dealers simply chose whatever suitable width rims they happened to have in stock.
