A Vietnam Airlines plane’s tire was punctured as it tried to land at Ho Chi Minh City’s Tan Son Nhat airport last Sunday evening.
At 5.49pm, Flight VN503 departing from Guangzhou, carrying 136 passengers and 8 crew landed on the runway but did not stop until it had passed 50m from the end of the touchdown zone.
According to airport information, the runway was slippery due to heavy rain and a tire of the plane was blown off as the pilot was braking hard.
Vietnam Airlines said their crew carried out safety measures and managed to land at the end of the runway.
After the plane had stopped, Vietnam Airlines took more than an hour to repair and replace the tire at the site before they towed the jet back to the factory for technical tests.
The plane that encountered the problem was an Airbus A321-231, manufactured in February 2007 and in operation since. The plane’s last periodical maintenance was on April 27 this year.

Additional information from the local papers.
The over-run is reported as occurring at 1749 local (1049 UTC), which is after the significant weather highlighted in Sunnyjohn's post and according to the Metars, 07L would have had a slight tailwind component. The weather on Sunday afternoon was typical early-rainy-season with light scattered thunder showers, moving from west to east.
07L/25R is 10,000' long with 1000' stopways at either end, elevation 33'.

I have just noticed that the weather data in Sunnyjohn's post are TAFs, not Metars.
Here are the hourly reports (presumably Metar decodes) from Weather Underground:

4300 hours. 200 in training. 4000 reading the newspaper. 100 with both eyes blinking rapidly 
Another lucky break for them. Don't worry though. 100 cadets coming soon to save the day.
Captain with 4 years flight experience. F/O with one year. I wonder if the traveling public knows about this skill and experience level when they buy a SkyTeam ticket. Apparently the VN airports know since you can't find anyone dumb enough to sell TRAVEL INSURANCE there!!!

Rubbish; they are METARS. When did you ever see a Temperature and a Dew Point in a TAF?
Also, every TAF I have ever seen always gives the time group to which it refers, the quoted Weather reports are the actuals, ie METARS, at the standard 30 minute intervals.
When did you ever see a Temperature and a Dew Point in a TAF?
Because there are temperature forecasts in TAF also (TX for highs and TN for lows)
TX and TN are forecast high temperature and low temperature so that we can do some forward performance planning (among other things). No TAF ever contains the ACTUAL temperature and the ACTUAL Dew Point (or any other kind of dew point for that matter).
Furthermore, as Top Bunk also says, every TAF must contain the date/time group at the beginning of the forecast period and the date/time group at the end of the forecast period.

Was just privy to the DFDR decode…..
Aircraft touched down very smooth about 15 knots over Vapp in Heavy Rain.
Before Autobrake "low" was fully active, the right brake pedal was pushed thereby deactivating the Autobrake (it's been suggested that it was pushed by the F/O)
ELEVEN SECONDS later the brakes were pushed heavily and the aircraft vacated the runway. All main tires destroyed. Local A**bus rep say that they need to replace the landing gear. A/C is leased.
more as I hear it…..
