Most of the 16s still out there are for mid-80s Corvettes, Ferraris and Lambos. That's why you see the higher speed ratings for them. The best speed rating that you will probably find in 15's are H (130mph). I'm not sure what the Goodyear Blue Streak/Billboard bias ply tires are rated to, but there are several guys that can attest running well above a buck thirty with them.
