Tracer.....What kind of equipment are you running, and what size tires on the truck? What kind of mileage are you getting out of your tires? I'd be interested in hearing about your experiences on this.

I created a post to see if I could find some information on 19.5 tires. It has been difficult to find some, and this thread is related. 22.5 tires have a production max speed rating of 75 mph. Take into consideration this, a full load, and operating in say AZ during the Summer and I'm amazed more tires don't fail. I can't remember exactly where I read this, but the article was making the point that the new aerodynamic truck shapes are reducing the airflow over the tires reducing the cooling, and that the heat from larger brakes (discs will likely alleviate much of this) was adding to the problem. It'll be interesting to see if we start seeing drive tire failures here pretty soon (2010) because of the heat stress. Well not so much so if you happen to be driving it at the time:).
