There are a couple of different size modern equivalents to the 78-14 tire size. But for an H78-14, you would need to use an ST215/75-14, see link. If you just want tires, we have bias tire # AM1ST90 and for a radial we have # AM10229. Make sure not to mix radial and bias tires for best performance and longest life of the tires. I have also included a link to our tire FAQ article for you.

If you need a tire and rim and you have a 5 on 4-1/2 inch bolt pattern rim you would want a Karrier Rim and Tire # AM32181.
