Nearly all truck tires have been built for a maximum sustained speed of 75 mph since the middle of last decade, when drivers across the vast majority of the U.S. were allowed to go no faster than 65 or 70 mph.

Nearly all truck tires have been built for a maximum sustained speed of 75 mph since the middle of last decade, when drivers across the vast majority of the U.S. were allowed to go no faster than 65 or 70 mph.

But 14 states, mainly west of the Mississippi River, now have speed limits of 75, 80, even 85 mph in part of Texas.

The practice of driving at or above the limit the tires can handle has been linked to wrecks and blowouts.

Here is a look at the top speed limits for cars in trucks in all 50 states and Washington, D.C.
