I have a set here which are as new with all parts intact. They measure 124” X 20”. I just wonder if anyone knows off-hand if these will fit the N series. Dave

Dave, it depends on the size of your rear tires (24" or 28" or ?) and the type of chain (ladder, duo-link, ring, ?). For 11.2 x 28 tires, 120" sounds a little short to me, but that is a guess. Why not try them on your 8N to know for sure?

Well Ed, the tractor which they are being purchased for has 13.6X 28” tires. I am trying to sell the chains. I had hoped there would be a chart somewhere which showed sizes and what they would fit. Dave

AFter reading Dean's response, I did a search and found a Laclede tractor chain catalog online. For your tires, you need a Duo260 and the specs are in the link below.

Went through this a few years ago and did find a chart but did not keep url.

IIRC, it is available on one of the large tire chain vendors website. Do not believe it is tirechains.com but could be.

Got it! Well, an 11.2x28 tractor tire is usually about 48–50 inches tall, giving an outside circumference of approximately 48–50" × 3.14 = 151–157". Your chains seem wide enough, but I don't think they are long enough.
