I have a used 2016 Scott Solace Premium on the way to me (got a good deal, couldn't resist). This will be used for casual road rides and commuting to work. Its an XXL and I'm a tall/big guy, so I'm wanting a big volume tire. From what I've read, I can fit 30s on it. My question is, are there any 30s that will give me any advantage over the more common 28s? I'll be on pavement 95%, but it might be rough pavement, and some pretty smooth gravel/dirt trails when they're dry.

Thanks in advance.
