As a person who enjoys flying and a Delta loyalist tell her to keep all of her receipts. Send them an email, explain the issue, attach itemized receipts/invoices, include your address and other details, and ask if they can mail you a reimbursement check. If it's their fault (not the weather etc), they will likely send at least partial reimbursement (they have limits based on each city). Airport agents have nothing to do with this by the way, and don't call, send an email or use the written Contact Us link on the website because they will want copies of receipts. Side note, tires did exactly what they were designed to do. The brakes overheated due to an overweight, high-speed brake application and the thermal plugs in the tires melted. Thus allowing a controlled tire deflation. Seen this many times during my time in the Air Force. Glad she's safe!
