Nitto drag radial speed rating
#6
You should be fine. It's only at extended high speed runs where you might run into any problems. Besides, almost all drag radials/slicks have a very low speed rating, if any at all. The Nittos have the highest speed rating I have seen out of any of the drag radials. The BFG drag radials only have an R rating, and I don't even think MT advertises a rating for their DR. Take your car somewhere else to have tuned.
