This explains it. A bit of runway rash on the nacells too.

O.P.I.: System Safety
Narrative: The Air Canada Airbus A320-200, C-FMSX, was operating as flight ACA 547 from Las Vegas, NV (KLAS) to Calgary, AB. During the take off roll on Runway 25R, at about 100 knots, the flight crew heard two pops and experienced a pull to the left. The take-off was rejected and the aircraft was brought to a full stop on the runway. Both left main landing gear tires had failed resulting in the aircraft sliding on the rims, which were ground down to the axle by the time the aircraft stopped. The right main tires and right-hand nose gear tire deflated during the RTO. ARFF was requested and the passengers were deplaned via air stairs through the front left main cabin door. There were no injuries or fire. There was skin damage on the left engine nacelle, flap canoes, and lower wing skins from the failed tires and rims. There was also FOD damage to the left engine main fan blades, but the engine core was fine.
