I am in the process of purchasing a 40 ft flatbed trailer ( bigtex 22 gn) 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??
