Street Radials. Speed ratings

When Montana ditched their “reasonable and prudent” speed limits, tire speed ratings over 100mph became pointless for 98% of drivers buying tires here in North America.

Speed ratings are almost like hp ratings. 112mph vs 118mph. 265hp vs 271hp. Almost entirely for marketing reasons. If you’re going to ‘feel’ better rolling around on 118mph tires, buy them but, as others have pointed out, you’re not going to be travelling at 115mph for sustained speeds to justify buying the 118mph tires over the 112mph tires.

Can you picture this classic scene?
Tommy: Chicken wings! Let's think about this for a sec, Ted, why would somebody put a guarantee on a box? Hmmm, very interesting.
Ted Nelson: Go on, I'm listening.
Tommy: Here's the way I see it, Ted. Guy puts a fancy guarantee on a box 'cause he wants you to fell all warm and toasty inside.
Ted Nelson: Yeah, makes a man feel good.
Tommy: 'Course it does. Why shouldn't it? Ya figure you put that little box under your pillow at night, the Guarantee Fairy might come by and leave a quarter, am I right, Ted?
Ted Nelson: What's your point?
Tommy: The point is, how do you know the fairy isn't a crazy glue sniffer? "Building model airplanes" says the little fairy, well, we're not buying it. He sneaks into your house once, that's all it takes. The next thing you know, there's money missing off the dresser and your daughter's knocked up, I seen it a hundred times.
Ted Nelson: But why do they put a guarantee on the box?
Tommy: Because they know all they sold ya was a guaranteed piece of ****. That's all it is, isn't it? Hey, if you want me to take a dump in a box and mark it guaranteed, I will. I got spare time. But for now, for your customer's sake, for your daughter's sake, ya might wanna think about buying a quality product from me
