If the leaf spring stack is currently attached below the axle, which is what it sounds like, then you can use an over/under conversion kit. If the axle is 3 inches in diameter then you can use # K71-385-00. If the axle is 2-3/8 inches in diameter use # K71-384-00.

If you do not have a round axle or if the diameter is bigger than 3 inches or smaller than 2-3/8 inches then you can raise the height be welding new spring seats to the top of the axle.

I am not sure why they would have put car tires on a trailer. Car tires should not be used on a trailer because they are not constructed properly for trailer use. Trailer tires are built with a thicker sidewall to handle more vertical load. I have included a link to our help article on trailer tires for you.
