10" tires for 14" rim

[neverfinished]

i have rims that are 14 x 9 3/4, and so i need tires in the area of 275 or larger but i'm having trouble finding any for a 14 inch rim, my car is a street car and i dont really want something as soft as mickey thompsons, but its all i can find, does anyone know of any other options? aside from 15" rims, i cant afford new rims and tires
