Craig, The newer Maxxis tires may have the speed rating on the sides, however the 8008 tires I just received from Discount Tire Direct did not, but they were built 6 months ago also. Here is the response I received directly from Maxxis on their tire speed rating;

David,
The Maxxis M8008 ST Radial is "Q" speed rated. However, according to the Tire and Rim Association, the U.S. tire industry specification authority, inflation pressures and load specifications in general for any ST Radial trailer tires, without a service description, regardless of the manufacturer, are designed and rated at 65 MPH. If the speed is higher than 65 MPH, the pressure and load need to be adjusted according to the following guidelines:
From 66 to 75 MPH – the tire inflation pressure needs to increase 10 PSI (not to exceed the maximum PSI the tire is rated for) but requires no load adjustment.
From 76 to 85 MPH – the tire inflation pressure needs to increase 10 PSI (not to exceed the maximum PSI the tire is rated for) and load should be reduced by 10%.
We hope this information is helpful. Thanks for your inquiry and interest in Maxxis Tires.
Best Regards,
Your Maxxis Support Team

So, Maxxis says the tires have the ability to handle higher speeds depending on load. Refer to their load chart to verify. Here is the chart;

Thanks David,

I was thinking it was restricted to 65mph since it is not on the tire but I can see the difference when looking at the load/inflation chart.
