Problems buying RE-11 due to weight???

280z/300zx

So I got a nail in my tire today and decided while I was having it repaired I might as well just order my tires that I've been holding off on. Still on the stock tires for my 2010 NISMO with 6 32nds in front and 5-6 32nds in the rear. Anyway, I tell the guy I want RE-11's and he says no problem. Then as we get to the checkout part he says the computer won't let him. He stated that the front tire on the RE-11 is only rated at 94W while stock requires 98W. He said that not only is it a danger for the tire separating from its self but that they wouldn't even be able to mount it if I wanted to disregard the warning.

So how are so many other people running this tire??

On a side note I noticed that the PSS are now available in NISMO sizing. Out new is the 285/35/19. Told the guy to just order me these but of course this tire is on back order. Still, I might wait it out since I still have some tread left to spare. I originally wanted the PSS but it didn't come in the 285's, but now it does
