quick question about nittos

Maybe they weren't when they first came out, but have since been approved?
. He's saying that the 555R's (the drag radials) are DOT approved, while the RII's (auto-x tires) are NOT. BFG DR's and Mickey Thompson ET Streets (inc. Street Radials) are both DOT approved as well. There's no argument about that. The tires currently in question are the 555RII's (but the Nitto site says they're DOT approved, so maybe that's something that's recently changed?
).
yea i think both the 555R's and the R2's r both now DOT approved.... i plan on getting 555R's for summer DD use.... i want to be able to hook great on the street... if i get caught in a bad rain i will just take it easy i guess :/
Are you sure about that??

Still wonder what makes them legal/illegal.
I don't think it has "just" became DOT approved. The reason I say this is that I have had then on my Z for the last few years, and if they weren't DOT approved, I doubt they would put them on my car and let me drive off on the street without at least mentioning that they weren't street leagal.
AFAIK, they were DOT legal since the get go. they are pretty much the same tire as the 555R with a sidewall stiffener.
