The "house" tires at certain retailers are often not really "different" from the mainline tire except for the name, and for slight differences in the tread pattern. A few examples:
Michelin's mainline passenger all season tire is the Harmony. They also make the Destiny for Discount Tire, the WeatherWise II for Sears, and the X Radial for warehouse clubs like Sam's and Costco. Internally, and with respect to the rubber compound, they're the same tire. There are some slight differences in the shape of the sipes and cuts of the tread pattern, but when you compare them side-by-side, you can see that the overall "template" is the same. When Consumer Reports tested passenger car tires back in 2005, they included three of this tire line: the Harmony, Agility [which is now called the WeatherWise II], and the X Radial. The X Radial actually scored the best of the three, and placed #2 overall in the test.
Goodyear's mainline passenger all season tire (or one of them) used to be the Regatta 2. They've had that tire for a while now, and it's showed up in various forms at Walmart and at Sam's Club. Walmart carried the Viva Touring, which was basically the Regatta 2 with a name change. Sams Club carried the Allegra. The Allegra was a heavily-siped tire which reportedly did EXCELLENT in the snow. Again, it was simply a Regatta 2 with a slight tread pattern modification.
More currently, Goodyear has the Viva Authority Fuel Max at Walmart. If you look closely at the tire, you can see that it's a near-clone of the Assurance Fuel Max sold at most other Goodyear retailers. Sam's Club now carries the Assurance Touring, which is based on the Goodyear Assurance.
As stated prior by somebody else, they do this so they don't have to price-match other retailers. This is common in many industries. You can often find the "same" printer at Best Buy, Staples, Target, Walmart, etc. They all have slightly different part numbers, and sometimes the plastic farings are shaped a bit different, but it's the same printer, taking the same ink, and using the same drivers and software. This way, Target can set its own price and not have to price-match directly with Walmart. Of course, prices still stay competitive, but they don't have to worry about missing somebody's President's Day sale or something like that.
I would caution against a judgement about tire quality at warehouse clubs (or any "house" tire at a retailer). They're often the same tire you can get at a mainline retailer, but without all the TV advertising. When's the last time you saw a Michelin ad for the X Radial on TV? (Hint: never. They're pushing their Energy Saver A/S and HydroEdge, etc.)
