What type of tires do utility bikes usually have and how much pressure do they typically hold?
I ride a 7 speed cruiser with wide tires rated at 40psi that I use mostly for grocery shopping. It feels a bit "mushy" when I have a load of groceries in my rear baskets (two side baskets and a milk crate on top).
Does this matter? Will it reduce the life of the wheel or bike in some way?
Should I (can I) inflate the tires to a higher pressure than they are rated for? How much?
Should I get different tires? What psi?
