Was merging on to the Interstate today and see a truck and TT coming hard on the inside lane. This is a 3 lane wide section with a 60 speed limit. I merged on and backed off at 78 just to see how fast he was going. 78 wasn't keeping up. This was a Passport Ultra Lite single axle. Guess it takes all kinds. And no, I wasn't pulling mine today. Wonder if those were China bomb tires? Wouldn't want to find out myself.
