Pros
It depends on what region you are in. Some regional sales managers are better than others. Some are not very intelligent and not caught up on the times. It is a stable job with decent (but expensive) benefits. They do not like to fire employees, generally speaking.
Cons
The company as a whole has a very bad reputation in some parts of the country. They make a decent, sub top-tier commercial product, offered at a top-tier price. That will make it more difficult for you to sell. Very negative culture, where everyone will blame someone else. No teamwork; plenty of backstabbing. Some managers are stuck in their old school thinking ways, will shun new ideas, and play favorites. They do not value formal education in the slightest. They put on a facade with the fancy headquarters building, but do your research in to Akron, OH if you plan to go the corporate route. It's not a pretty place to be. Folks have a tendency to get complacent and stay with the company for an extended period of time. Sometimes their whole career. While this can be a good thing, it's often a con, as they rarely open up to fresh ideas. Managers are promoted purely on tenure, rather than merit, so oftentimes they have no business managing others. Expect a manager, not a leader. This type of culture breeds mediocrity - a fact represented by their stock price (down 65% in the last 1.5 years) and their decreasing market share to Bridgestone and Michelin. Corporate senior management is doing okay, but going back to the tenured promotions, they aren't necessarily the best or the brightest for the job.
