Tim McGraw and Kenny Chesney have been in the country music biz long enough to know what fans want – and what they don't.

"I tell you what we won't be doing on tour – love ballad duets!" Chesney, 44, tells PEOPLE Country's July issue. "That time of night, in a football stadium, they want it loud and fast. That's what we'll give them."

The friends and touring buddies also give country fans tons of insight into their 21-year friendship in the new issue, including what Chesney thinks of McGraw's wife, Faith Hill, what their moms have in common, and what they've enjoyed doing together over the years.
