Murray tractor select model 30577x8a won't start. Had battery checked - it's fine.

Tractor had a bad tire- got the tire replaced with a new rim and tube, that's when the problem started.

Tractor does not turn over- nothing - silence...

Probably has to do with all the safety wiring and switches, (you must be in the seat, break or clutch pressed and blades disengaged) to start. Something disconnected in this wiring in process changing tire. Only logical thing it could be.
