Higher Speed Rated Trailer Tire for 17-1/2 inch Diameter Wheel

Question

Question:

i am in the process of purchasing a 40 ft flatbed trailer and the dealership talked me into the beefer 17.5 tire upgrade, with a load rating of h. sounded good to me at the time, but....... from what i have found online, all of the st 17.5 tires have a j speed rating or slower, does that mean that i am limited to 62 miles per hour??? are j speed rated tires even worth having considering most highway speeds are70, 75 miles per hour? is it even allowed by dot? or should i have gone with a g load rated tire for otr trucking?? please help!!!!

We have the Provider 215/75R17.5 Radial Trailer Tire # TTWP15175 which has an 81 mph speed rating. This is a Load Range H and has a capacity of 4,805 lbs at 123 psi. Not every tire and Load Range will have the same speed rating though. You'll have to check the sidewall of your tire to see what the rating is listed as. Most of the other tires we offer in this size though are 62 mph.
