I found this set of tire chains with the packaging open already. I do not see any signs of installation or use on them. According to the bag they are for 18x8.50-8 size tires and the John Deere part number is TY15717. Please verify these will fit your exact tire size before ordering. I am not responsible if they do not fit for you and they will still be yours. Absolutely No Returns/No Refunds/No Excuses. Thanks for looking.
