Many tractor-trailers on the nation's roads are driven faster than the 75 m.p.h. their tires are designed to handle, a practice that has been linked to wrecks and blowouts but has largely escaped the attention of highway officials.
Posting this because all of our motorhomes are running on truck tires--not sure what rating is on them though. This may not apply to many of us, though, as RVers tend to drive slower than the speed limit...not faster.
Hopefully if Michigan adopts the 80mph speed limit, it will come with stiff fines for big trucks traveling that speed. Unfortunately, there are not many police out on the highways in this state enforcing the limits.
I usually keep my RV at 60mph or less, and the 3,000 miles we drove it last year, I think I passed a total of 3 other vehicles.
