Are you sure your tires are not "D" load rated, according to the tire chart that I have there is no "C" for an ST145/R12. The "D" rated load range requires 65 psi and with a max load capacity of 1220 lbs. It looks like if you want to go to a larger tire, the next step is a ST175/80R13, If this is the case then the rims will have to be changed. Check with your local tire dealer just to make sure.
