Okay well it came to me that i have knobby tires and maybe that isnt the best for what i do. I have a HT bike with 26" tire. And the thing is i do a lot of everything, I ride to and from school and thats 8 miles/day plus anywhere else i want to go. And then usually on weekends I go on the trail and about once a month i go on some jumps. But i know knobbies are not the best for road travel so i hear, so what tire should i use?
