No, you would have to work out the profile, as race tyres are done differently.
Race tyres will be the width x diameter. Road tyres are width x aspect ratio (in your example 40% of 195 would be 78mm, which is the sidewall height).
You would have to calculate the sidewall height of the 620mm tyre like this:
16 x 25.4mm = 406.4mm (the diameter of the wheel).
Subtract the wheel diameter from the tyre diameter to get the total tyre height: 620mm - 406.4mm = 213.6 / 2 = 106.8mm sidewall height.
As an aspect ratio that would work out as 200/53 x 16.
