I seem to have run myself into a bit of a conundrum. I bought the new schwalbe road cruiser green compound tires for my district, which is entirely used to ride on pavement and sidewalk (no place to ride on road surface on bell road unless I wish for death) and they seem to be flatting fairly frequently, as in once or more a week. I would like to move to a tire with more flat protection but schwalbe doesn't make anything in 32mm with a decent guard rating outside of the marathon plus. Thinking of moving to the marathon GT because this bike almost never sees off road but the smallest it comes in is 35mm. Would I lose much in the way of How nimble my bike feels moving up 3mm? They will still fit under my fenders, I have a good quarter inch at the lowest point.
