Tinker, a three-star wide receiver from Pittsburgh, had a good trip out west last weekend.
"Everything went good," Tinker said of his visit to Colorado. "Everything was beautiful and the whole atmosphere was nice. The coaching staff was good and the players were pretty good too. It was all nice to me. Right now, (Colorado) is the leader."
Minnesota looks to get Tinker next on campus.
"Minnesota wants me to take my official visit on (September) 22nd or on the 29th," Tinker said. "Hopefully, one of those dates fits my schedule. I'm going to take a visit to Michigan State, Iowa and West Virginia. So those are other visits I'm going to take but I don't know when."
Though Tinker lists Colorado as his current leader, he told InsideTheVille.com that he probably won't make his decision until closer to signing day. And while he didn't mention Louisville on his potential visit list, he's still considering the Cardinals.
"I'm waiting for them to send me a letter because all the schools have sent me a letter showing me the days I could take my visit," Tinker said. "They're still on my list and everything. Hopefully they will send me a letter so I'll know which days I can take my official visit."
Louisville assistant Greg Nord is recruiting Tinker, who is a close friend of Louisville quarterback commit Tino Sunseri, who plays for Pittsburgh Central Catholic.
"He really wants me to go there with him so he has someone to throw the ball to," Tinker said. "He's a good guy and I have a real good relationship with him."
Asked which schools are recruiting him the hardest, Tinker said: "Probably Louisville, Minnesota and Iowa. Those are the three schools that have been sending me the most mail."
Three big factors will help Tinker make his college decision.
"I want to play my freshman year," Tinker said. "I want to have a good relationship with the coaches and the players and I want to feel comfortable with the whole environment."
