It is not a trailer tire in the 145 13 size. Try Coker tires. They stock them.

dvjoiner - 7/1/2018 8:26 PM have anyone use car tire on you hack having time finding trailer tire for my hack 145/R13/75t

75T is not part of your tire's size. 75 is the load rating and T is the speed rating. So you need to look for a 145R13, or a 145SR13, though that's an alphanumeric size which isn't used much anymore. The equivalent P-Metric size is a 145/80-13. With that info, you discover that Achilles is making a modern radial in that size called the Achilles 122. It has an excellent UTQG rating (400AA), it has the same 75T load and speed rating as your old tire, only costs $35 plus shipping, and is available online [ https://www.tires-easy.com/145-80-13/achilles-tires/122/tirecode/MAF148013 ] If you don't mind paying a little more, you can order one at Walmart.com and get it shipped to your local Walmart.
