Cirrus SR20 pilot reported a main gear flat tire during landing roll out. Pilot notified ATC and aircraft was subsequently towed.

Narrative

Night landing. Tower closed. Landing fine but when slowing noticed hard to get to turn back to right. Assumed flat tire and shut down on runway. Tire was indeed flat and would not air up. Not a hard landing Tried to call ZZZ1 from radio but could not reach on ground. Called ATC on phone and they were awesome. Said they would monitor ctaf and could advise incoming traffic. Asked them about Notam to close runway and they started that process. They asked me to call back when clear. ZZZ turns class g at XA:00 from class d. ZZZ sent some help as I did not want to damage wheel towing or moving with flat and possible rubbing wheel. Cirrus has 24 hour tech support and worked with me and airport personnel to get a dolly under the main wheel so it can be towed. Excellent support by cirrus; ZZZ1 ATC; and ZZZ airport. As smooth a it could have gone. My takeaway was as I was concerned about an incoming aircraft not seeing plane on runway even though I had lights on. Reaching ATC on phone was right move and i think every pilot should keep an ATC number in their cell phone.
