If it's 29er, the 2.5 Aggressor is almost 1000g, which is a bit excessive for a rear tire. Be sure you're running the 3C maxxterra DHF with the Aggressor.
I really like the 2.3 3C DHF with the 2.3 Aggressor for normal trail riding, but might try the 2.5 DHF 3C with it. Though I'm more likely to run the 2.5 DHF 3C with a 2.4 DHR2 DC for rugged trail riding, and take the rolling resistance hit.
