The DMack 175/70/14 tires that I use are 23.42 inch Diameter. I like the additional tire height, perhaps it is not a valid reason dependent on sidewall construction and suspension specifications (not 12 inches of travel - just near stock travel).
Maxxis175/65R14 23.1 vs DMack 23.42 inches (595mm)
Maxxis185/65R14 23.8 vs DMack 23.54 inches (598mm)
I believe that I would prefer the wider/taller tire.
Do have a cost or information on the construction of the tires?
