The closest we have to what you're looking for is a 145/R12 size tire, Load Range E rated for up to 1,520 pounds at 80 psi, but its speed rating is only 65 mph. It's the only Load Range E tire we have at that size and we don't have any for a 13 inch rim.

Another option that may work for you is tire # TT53012C. It's a 5.30R12 size which is about a 1/2 inch skinnier and a 1/*4 inch larger in diameter. It does have an 81 mph speed rating however it's only rated for 1,050 pounds as a Load Range C. As long as the weight capacity is enough this is a good option for you.
