I have 28 slicks on it right now as I only ride roads, but I know it can accommodate 32, not sure about 35. When I say I only ride roads, I've literally never ridden anything but a road/concrete.

I live in Pittsburgh, so I don't really need to pack anything other than the basics I typically bring when I go on a road ride, i.e. spare tube, pump, multi-tool, two water bottles, wallet, money, and some small energy type snacks. I plan to stop on the trail to buy extra water/food. I can also plan this for a dry week and weekend so the trail will be solid.

My main question is tire. I don't mind buying a set of 32, but would prefer to not spend money for no good reason. If I do buy a set, should they have significant tread, or can I get away with something like the Schwalbe Marathon Supreme (won't let me link to make it easier for you to look - sorry). Also, is there a special consideration that I am overlooking with a ride like this? I'm treating it like any other road ride where I park and go. For example, does the difference between a trail and road make this ride harder than a century on roads?

I really appreciate your thoughts/input. Stay safe out there.
