Certainly the makers have price as a major consideration. I found I liked the stock tires on the Silverado, Goodyear Wrangler SR/A which are M+S pattern but no mountain/snowflake logo. They're quiet and smooth on pavement, which I'm sure is the other factor the truck and car manufacturers insist on so their vehicles show well in test drives at the dealerships.
Everyone has their own needs for tires. My truck goes up the very steep twisty Apex road every weekend. There's typically a 10 degree temp change between the village and the valley bottom and those tires haven't struggled with the changing conditions yet. 165,000 km on the truck now and I haven't spent $800 on tires yet in that lifetime.
