I know, old post but I couldn't resist. What you care about is the tires load rating, as long as its at or above the factory rating it's as "reinforced" as it needs to be. Also, the "B" in a tire spec means BIAS PLY, you DO NOT want a "B" spec tire on the K16. You want a ZR rated tire with at least a 58W front and 75W rear load rating.Does anyone know if these will be a RE-INFORCED TIRE? How about a "B" rating to boot?
I know the PR2 and PR3 tires and the Battlax tires are not.
The answer is always "NO" unless you ask.
