These are Titan rims.  The first rim has very little cracking and would defiantly be useable if you use the solid ring on the bolts like on most new combines. This is the rim on the right looking at the page I will point out it has one small crack on 10 o'clock hole.  These were on a  R75 with 1800 engine hours. Mine had the round spacers on the individual bolts.  I think this is most of the problem on these rims.  I luckily found 2 rims on a tire dealer closeout and got a big break on 2 of them, so I just replaced both of them (I added the solid rings). I would have only bought one and re-used the good one if I would have had to pay full price. 

I want 250.00 for the good one and zero for the other. although the solid ring might save it too.  here is the catch I want them to both leave together.

These rims are $2300-2500.00 new 

The new style gleaner two-part solid rings are 200 for a side.

Case IH guys these are the same thing on 2188-2588 even some 7088 combines.
