So we bought our LC from a dealer in April. The tire pressure has always shown to be much higher on the spare - which I have always thought was odd. I have occasionally noticed pictures of others' tire pressure displays showing the spare the same as the rest... So is my spare crazy high and should I lower the pressure? Or should the spare be kept at a higher pressure for some reason? I just have the stock Michelins on the stock 18"s and we live at about 5,000 ft above sea level..
