Used, but newer combine tires with checking/cracking

I was needing a pair of 23.1 by 26 combine tires and a farmer nearby has a pair that he says travelled only several hundred feet into the field before the combine gave out permanently. You can tell they are nearly new as they still have some of the thin rubber pieces hanging on them from the tire mold. The problem is on one section of one tire there is a bunch of checking / cracking. Cracks randomly here and there - up to 1/4" deep. Slight width - some up to 1/32". Not on the side wall, but in between the lugs. Maybe covers 12" to 16". Cracks sort of follow an imprint left by the tire mold. Possibly was stored in the sun and this area got the blunt. They are Titan tires. 10 ply. Am I ok to go ahead and buy them since they are 10 ply and the sidewalls are like new??? Just never seen that new of tire get checks. Will use on either a JD 4420 or 6620. Wrong rims - will have to change them to mine. Might get the pair bought for $400. What are they worth???
 
400.00 is cheap , as the sell for about double that for a pair and more. your call but i would take the chance as not the most popular tire at a good price. if you get a couple years out of them nothing lost.and factor changeover price also.
 
I would take a chance on them. Keep them aired up so they don't flex and heat up and they will last a long time.

However, combine tires... Are you straddling rows, or are you running on soybean and corn rows? Soybean stubble is going to like poking into those cracks.

Sounds like stubble damage to me. Another reason to combine soybean rows at an angle- spreads possible damage across the entire face of the tire, instead of concentrating it over the rows.
 
$400 is a good price for tires that are worth 4+ times that, new. Is the cracking across the tread, through the cleat and all? If so, it might be de-laminating at the seam. If they have several years on them, they will be harder than new tires, might actually last longer than new tires. I've read that several large farms buy tires and let them age, to harden up, prior to mounting on combines that straddle corn rows. All my tires are hard with age, too cheap to buy new, and the devil dances in empty pockets, if you know what I mean...
 
Go buy them now! Cracks in the tread area don't bother much. A 10 ply should carry a 4420 or 6620 without any problems unless the 6620 has a huge grain tank and is run down the road a lot with a full tank. A front combine tire will blow out just above the bead, I've seen more than I care to see do that, but these were on bigger combines at $6000 a tire. Jim
 
If it only covers a small part of the tire, it was from the ground where the combine sat. I would run them, OR "they're junk- don't buy them" and tell me where they are!
