I brought my Nissan Grand Livina, on November 2012 and got it on my birthday last year. for a few months noticed that rear right tire has been a bit flat, suspected that there was a bit of leak, every few weeks I had to fill it up. On 29 May 2013, It went totally flat, and I changed it for the first time. checked the stuff at the back and was impressed with the content, the tool bag was comprehensive, and there were two triangle reflectors. Just had fun and placed it a distance from the car while I changed the tires. I wonder if that is standard now a days, or is it just from nissan.
