I'd just say up to 175/14 and be done with it. You cannot list every tyre it will fit. If 175/14 is well in, you are covered.

C (for commercial/van tyres) rated tyres are not bigger in overall diameter per se, but may be a higher profile than other tyres, plus they don't always have the profile on the sidewall info or stated in spec., but are generally 80 profile.
You can calculate the overall tyre diameter fairly accurately if you know ALL the tyre figures including the profile from specification or sidewall markings.
Bit confusing because wheel diameters are in inches whilst tyre widths are millimetres, but simple conversion of 25.4mm to one inch makes number crunching fairly simple. The profile is the width to height ratio of the tyre, 70 profile is 70% as high as wide.
Overall Diameter = Wheel dia. plus ((tyre width x profile as a percentage) x 2)
Example: For a 14 in rim and 175/70 tyre
OD = 14 plus ((175/25.4)x0.7) x2) = 23.65 inches (or 600mm)
For a 14 in rim and 185/80 tyre
OD = 14 plus ((185/25.4)x0.8) x2) = 25.65 inches (or 651mm)
Why not simply go by Millenco description for your particular clamp

Google tyre size calculator & you will find charts that compare tyre size diameters.
