Carlisle Tires I don't agree with your hot-weather BS, yeah tires blow more often in heat, that's what causes them to FAIL 90% of the time, however, with a WELL made tire, the manufacturer takes into account the extremes to be encountered and builds a WELL made tire accordingly. Don't get me wrong, if you don't check your tire pressure daily while your towing, your an idiot asking for tire failure. I just had 2 Carlisle tire failures, due to faulty tires, not heat....it was raining and 48 degrees! We are the USA, we put people in space, we build tires that allow you to drive to where-ever, and when-ever you want, regardless of heat, time of day or what-not, I didn't have any blow-outs in Saudi in 90 and 91, and it gets plenty warm there.....and we really didn't have the option of driving when it was coolest in the morning....the Marine Corps has different ideas about that! ooo-rah!! Yes, it is a good suggestion, but by now means does it increase your odds "exponentially". Happy Campin ya'll!
