Narrative:

On arrival at the aircraft; the first officer observed the #1 left outboard tire was low. Maintenance was called and the #1 and #2 tires were serviced with nitrogen. All other tires were checked and found to have proper inflation. There were no other preflight issues noted. Subsequent passenger loading was uneventful. All normal checklists were executed. Engine start and taxi were uneventful. Before takeoff and runway line up checklists were complete upon arrival at runway xx at ZZZ. We were cleared onto the runway and issued line up and wait instructions. After the landing aircraft cleared the runway we were issued clearance for takeoff. Take off speeds were V1 137; vr 144 and V2 145. At approximately 120 IAS a tire on the left side of the aircraft blew. I simultaneously announced the abort and executed the abort procedures. I instructed the first officer to notify the tower that we were aborting the takeoff. He advised them that we had blown a tire and requested that the emergency equipment be sent. Shortly after the first tire blew the second tire on the left side blew. We had no brakes or tires left on the left side and pieces of the tire were being thrown forward of the aircraft. Max braking was continuously applied but we only had braking from the right gear. They quickly overheated and braking action became negligible. Nose gear steering was engaged at approximately 80 knots.the aircraft departed the end of the runway and went approximately 25 feet into the grass at which point it came to a stop. While the first officer exited his seat I executed the evacuation procedures. The first officer opened the left forward boarding door and exited the aircraft carrying the fire extinguisher. He checked for fire indications and observed the right landing gear smoking. We started evacuating the passenger and patient and then observed a fire starting on the right landing gear. The first officer put the fire out with the fire extinguisher he took from the aircraft and then assisted me with the evacuation of the passenger; patient and medical team. We assembled the passenger; patient; and all crew members upwind and away from the aircraft. An airport operations vehicle arrived and all crew members; patient and passenger were transported to a location near the terminal. They were then transported back to the FBO to arrange for patient transfer. There were no observable injuries to any passenger; patient or crew.

Title: Learjet 35 flight crew reported a dual tire failure during takeoff resulting in reduced braking capability during the rejected takeoff which caused the aircraft to depart the end of the runway.
