Another thread on how fast but from the drivers view. Have a drink.

Some folks insist that the "have" to drive at 70 to 80 while pulling 15,000 pounds of trailer on old, too small tires. I had to jump in with this reply.

My reply on forums like this one is from the viewpoint of trying to give the best answer from the point of extending the life of your tires.
Personally, as a retired professional race car driver, I don't buy the "Speed Kills" mantra. If that was true I would have died in the 70's when I started racing.
IMO it is inattention and the false belief that "I am the best driver around" that most people seem to believe. If you are listening to the radio you are not paying attention. Worse, if you drive and are having an extended conversation or listening to an audio book or the news, you are not paying full attention to the task at hand. Do you keep both hands on the steering or just a couple fingers from one hand? There are more but you should get the question.
Having only driven cross country 4 times I have a little experience but do not understand those who claim you have to drive the posted speed or "get run over". I set my cruse at 62 to 63 and do not recall anyone passing and honking their frustration. But then I keep to the right lane and keep an eye on the vehicles behind me so the occasions when I pass a slower vehicle I do not pull out in front of someone who feels they own the highway.

As a Tire Design Engineer, I know that tires have a finite life of cycles and tread wear is not the only limiting factor. The higher the load or lower the inflation or faster the speed or hotter the temperature or longer you park the tires in full sunlight, the sooner you will "consume" the finite life in any tire, no matter the brand. There are just too many variables to predict the moment when a tire will "give up the ghost". Also, tires do not always fail the instant you have done "fatal" damage to them. Sometimes it might take many miles or days or weeks to come apart and surprise you while you are drinking a coffee with one hand and steering with your knees.

This blog has over 300 posts on the numerous ways you can damage tires and shorten their life. I still get replies, almost every day, from those who think that because they haven't had a tire "Blow Out" or been surprised with a tire failure they know all there is about tire life and proper usage.

There is a saying a friend uses frequently. "You can lead a horse to water but you can't make them drink".  IMO this blog is  a large body of cool clean refreshing water, and it's free. Drink up.
