I asked him about the RCs for these, and here is his reply:

Ok according to my book
6-12 OD = 23.0 inches
7-16 OD = 29.2 inches

That could be just the overall diameter and not the RC, though I'm not sure what use the overall diameter would be for a tire manufacturer to list in a book.

If that is, or is close to, the RC, that would give me a front/rear ratio of 0.787. How do I know how that compares to the stock tire ratio (which were the same "size")?

Is getting the same size tires close enough?

Thanks!
Nope not any where close to an RC # for those tires, and no that's not the ratio.

I'm hoping your dealer is more competent in getting you the RIGHT size tires than he is at giving you information!

Yes, getting the right size is Very Important, the front end parts for your tractor would run you some serious CAD to replace because of badly matched tires.

You're not kidding Wolfman. I'm taking this so seriously because it might be the end of the tractor if I ruin the drive gear. I'm going to go back at him for the RC number tomorrow. I've asked for the make/model of the tires as well, but he hasn't supplied that yet either. Thanks again!

You want to be somewhere close to:
6-12 RC 68
7-16 RC 87

I'm sorry I was wrong you did have the right ratio it will be in the .78 range.
So it does sound like they are giving you the right tires.
Not trying to worry you, just want you to get the right tires.;)
