Tire Speed Rating Question
I'm posting this here because the speed rating of a tire seems to me to cross all lines/types of vehicles. Reading up on warranty issues/questions just now, I came across the following language ...

O.K...here's another poser- same subject, sort of.
Can anyone explain why Michelin Ribs, though "Q" (99 mph) rated if installed on pickups etc, are speed limited to 75 mph when installed on an RV/trailer?
See different specs at:
Ribs at Michelin Pickup page
Same tire at Michelin RV page
Thanks again...
I wonder if this is a difference in interpretation.
On the Pickup page, they don't specifically mention a maximum speed. It is only implied by the speed rating.
On the RV page, it is explicit. I wonder if Michelin feels the need to be explicit for RV's because of the fact that RV's tend to be use infrequently and tend to be loaded up pretty much all the time.
