Tire Question/Help

[Cub-Bud]

I recently purchased two new rims with tires mounted on them to use on my '45 B Farmall. One of the tires is in great shape and the other has some dry rotting/cracking. The tire pictured below is a Safemark Multi Track and is the tire I intend on using. However, Safemark was purchased by General Tire several years ago and General has since stopped making farm tires. Therefore, I have no good source to go to for a perfect match. I am posting a picture in hopes that someone knows of a tire brand currently in production that is a close/perfect match to the Safemark.
